For Ranch Wives Everywhere

“For ranch wives everywhere”

This time of year, when the cattle are being worked and shipped, is usually a time of high stress on ranch marriages – not unlike calving, lambing, planting, haying, combining, feeding, and all of the other seasons of ranch wife life.
Julie Carter of Carrizozo, New Mexico, whose ‘Cowgirl Sass’ articles sometimes appear in Agri-News, wrote these Ranch Wife 101 Guidelines, which seem very appropriate to share during shipping season. She is obviously a genius because these are good enough to hang on the refrigerator!

Never – and I repeat never – ever believe the phrase, ‘We’ll be right back,’ when he has asked you to help him do something on the ranch. The echoing words, ‘This will only take a little while,’ have tricked generations of ranch wives and still today should invoke sincere distrust in the woman who hears them.
Always know there is no romantic intention when he pleadingly asks you to take a ride in the pickup with him around the ranch while he checks water and cattle. What that sweet request really means is that he wants someone to open the gates.

He will always expect you to be able to quickly find one stray in a four-section brush-covered pasture, but he will never be able to find the mayonnaise jar in a four-square-foot refrigerator.
Always load your horse last in the trailer so it is the first one unloaded. By the time he gets his horse unloaded, you will have your cinch pulled and be mounted up – lessening the chance of him riding off without you while your horse tries to follow with you hopping along beside it, still trying to get your foot in the stirrup.

Count everything you see – cattle especially, but also horses, deer, quail or whatever moves. Count it in the gate, or on the horizon. The first time you don’t count is when he will have expected that you did. That blank eyelash-batting look you give him when he asks, ‘How many?’ will not be acceptable.

Know that you will never be able to ride a horse or drive a pickup to suit him. Given the choice of jobs, choose throwing the feed off the back of the truck to avoid the opportunity for constant criticism of your speed, ability, and eyesight. ( How in the $@*!&* could you NOT see that hole?’)

Never allow yourself to be on foot in the alley when he is sorting cattle on horseback. When he has shoved 20 head of running, bucking, kicking yearlings at you and hollers, ‘Hold ‘em, hold ‘em!’ at the top of his lungs, don’t think that you really can do that without loss of life or limb. Contrary to what he will lead you to believe, walking back to the house is always an option that has been exercised throughout time.

Don’t expect him to correctly close snap-on tops on plastic refrigerator containers, but know he will expect you to always close every gate. His reasoning is that the cows will get out, but the food cannot.
Always praise him lavishly when he helps in the kitchen – the very same way he does when you help him with ranch work – OR NOT!

Finally, know that when you step out of the house, you move from ‘wife’ to ‘hired hand’ status. Although the word ‘hired’ indicates there will be a paycheck (that you will never see), rest assured that you have job security. The price is just right, and you will always be ‘the best help he has’ – mainly because you are the ONLY help he has!”

MHBA ANIMAL HEALTH SERIES: Bulls, babes and breeding

By Peggy Joseph-Potter RN, BSN, MHA

Springtime means new beginnings, whether you decide to calve in the winter or spring it is time to start planning for the next calf crop. Developing a timetable and getting cattle bred and rebred on schedule is an important component of herd management. Taking the time to analyze your herd and to choose a bull with traits that accentuate your program can be the difference between success and failure.
Whether you utilize your own bull, AI, or rent one, cattle condition, soundness and health must be considered. Reproductive disease can be carried either by natural or artificial means. Maintenance of a comprehensive vaccination program is essential for a quality-breeding program. Testing for diseases such as Tuberculosis (unless herd has been certified TB-Free), trichomoniasis, BVDV also helps to ensure a healthy outcome.
For those interested in obtaining calves through the AI process, semen is readily available from a number of breeders. It is best to obtain semen from a breeder who is known to meet the generally established health standards in caring for their herd. AI success requires timing, good record keeping and a competent inseminator. Whether you utilize your ranch veterinarian, a reproductive veterinarian or an AI service references and success rates should be a factor in your decision.
In 1970s, Certified Semen Services, Inc., CSS, was formed to qualify and monitor the production of “health certified semen.” Semen obtained through this method must meet very strict standards, including quarantine and the donors must undergo multiple health related tests during their internment. A number of qualified facilities are available throughout the United States; these services perform the required housing, testing, and monitoring of the prospective bulls. Only semen meeting these tough standards is allowed to use the CSS logo. The CSS international qualification can meet the requirements for the export of semen however, each country has its own set of standards; therefore, it is best to involve them early as these organizations have a wealth of knowledge and can walk you through the procedure.

Tuberculosis (TB)
While TB is not a reproductive, disease it can rapidly spread to your herd through the introduction of infected animals or contact with wild or domestic ruminate mammals. The Mycobactium bovis. M bovis, is transmitted by aerosol, ingestion, or breaks in the skin. Like leptospirosis and Brucellosis, humans can develop the disease through contact with a sick animal or ingestion of infected milk. Testing must be performed by a veterinarian and is required for the movement of animals in states not deemed as TB Free.

Trichomoniasis
Infected bulls spread trichomoniasis, a true venereal disease. It can cause abortion in the pregnant cow, usually within the first trimester; however-late term abortions have been known to occur. The best defense against this disease is to utilize a virgin bull or one known to be tested by a veterinarian and deemed disease free. Semen is generally safer than live breeding as the freezing and dilution process reduces the effectiveness of the organism. A vaccine is now available to be use prior to the breeding season.

Bovine Brucellosis-Bangs Disease
Brucellosis, while rare, can have significant implications for livestock due to the threat of abortions; it is noteworthy if the cattle breeder also raises swine, sheep or goats. It was because of this great economic importance and the ability of the disease to cause undulant fever in humans, the United States government stepped in with vigorous elimination programs and now requires RB51 vaccine to be given to all female cattle between the ages of 4-8 months. Breeders who live near wilderness areas where their herds may encounter wild game need to be especially diligent in the protection of their livestock.

Bovine Leptospirosis
Leptospirosis is the most common cause of infectious abortions in cattle. It enters the cow through breaks in the skin and is spread by the urine of sick and carrier animals contaminating feed and water. About 70 percent of infected cows show little outward signs of illness, and they will continue to shed the bacteria in their urine for several months after recovery. Cows can abort even if they do not appear sick. Vaccinating with a product that covers the five most common types of lepto is your best defense against this disease.

Bovine Viral Diarrhea Virus (BVDV)
BVDV is a viral disease that can cause abortion, diseased calves and those with suppressed immune systems. BVD is the most prevalent bovine viral disease. It can be carried by affected animals, on clothing and vehicles. The virus can cause abortion at any stage of gestation, if the fetus survives it may continue to shed the virus as carrier or the state of BVD PI, remaining persistently infected throughout its life. Modified live vaccines are available and should be imperative for any herd health program.

Bluetongue
Buetongue is a disease affecting cattle, goats and sheep. It is seasonal and is most prevalent in the southern and western United States. The disease is caused by a specific midge biting insect, Culiconides varipennis. Infected livestock can develop ulcers and erosion of the lips, tongue and dental pad; abortion of a pregnant animal is not uncommon. Livestock are known to carry it however, sheep are the most susceptible. Vaccine is available for sheep, but not cattle or goats. Bluetongue testing is required by some states for the sale of breeding bulls and for the export of semen. CCS and major sheep producing countries such as Australia require a negative titer.

Have a safe and productive breeding season!

Animal Health Series: Calf Health Part 2

MHBA ANIMAL HEALTH SERIES

Calf Health Part 2

By Peggy Joseph-Potter RN, BSN, MHA

Raising healthy calves is the mainstay of our industry. Early intervention from birth through weaning makes all the difference in outcomes. Keeping your calf healthy and disease-free takes planning, early intervention and consistency. Calves are born without immunity therefore protection from opportunistic organisms and conditions requires daily observation and diligence to what Sheila McGuirk DMV, PhD calls the 5 C’s: Colostrum, Calories, Cleanliness, Comfort and Consistency.

Newborn Calf Protocol: Clean hands, arms and equipment (see calving supply list) if assisting the calving. Remove mucus from the calf’s mouth and nose. (We drain calves with large amounts of mucous by gently turning them upside down for a few seconds.) Rub the calf vigorously if stimulation is necessary. (Use warmed towels or blankets in cold weather.) Examine the navel and place a tie if it continues to bleed. Apply disinfectant to a clean navel. Iodine solutions (1, 2 and 7%) or chlorhexidine (0.5%) may be effective. Dipping is more effective than a spray as it also acts as an astringent that aids in drying out the cord. Feed 1 quart of prepared or thawed, warm colostrum if unable to nurse within the first two hours. (Some breeders supplement immediately after birth even if the calf is able to nurse.) Use either a bottle or esophageal feeder for those calves too weak to suck.

Colostrom: Good quality colostrom is essential to the survival of a newborn calf. A newborn should be up and nursing soon after birth or at least within the first couple of hours without assistance. After two hours, the calf may need additional support to stand and find the teat. First calf-heifers may need to be tied or even milked to ensure adequate and timely immunity for the newborn. As time progresses without nursing, so does the loss of immunity. A supplemental feeding maybe required to ensure the calf receives vital antibodies against disease and adequate nutrition, energy and calories to keep them warm. Good quality colostrum is thick and creamy in appearance. It is rich in calories and a concentrated source of nutrients for the calf. Healthy cows in good condition that have been vaccinated against rotavirus, coronavirus and bacteria are more likely to produce good-quality colostrum that contains antibodies required in the first few months of life. Inferior colostrum can result when cows are not in good body condition, from illness or inadequate nutrition, or when animals are first-calf heifers. Thin or watery colostrum should not be fed if there is a source of good quality colostrum available, either frozen or fresh. A lamb’s nipple and soda bottle make an ideal substitute for a calf unable or unwilling to nurse its mother. Colostrom comes either dried or frozen and should be kept on hand during calving season or whenever a birth is likely to occur.

Calories: Cattle require five main groups of nutrients for life and growth: energy, protein, vitamins, minerals and water. Mother’s milk and colostrum are the main source of calories and energy for the newborn calf. Calves need about 5-10 percent of their body weight or 1 quart for a 40-pound calf at birth and again in another 6 hours. Beef cattle should be allowed to nurse at-will as cows usually only produce enough milk to fulfill the needs of their calves; therefore over-feeding should not be a concern.

At 1 week of age, calves will begin to eat a little hay and grain. Consumption will be insignificant at first but it will gradually increase to become a major part of the diet by the end of a month. Calf developer products are specifically made to meet the nutritional needs of calves and medicated products assist with the development of good quality rumen and digestion. Providing the growing calf with adequate calories and nutrition leads to less weight loss and illness during the stress of weaning. Good nutrition is maximized by ensuring an adequate intake of minerals including salt and plenty of good clean water. (The injectable source of vitamin supplement we use is Multimin 90 by Nova Tech, other products are also available.)

Cleanliness: Calves should be born in a clean, dry place. Keeping the calving environment clean is important as newborns are exposed to large amounts of pathogens after birth. Maternity areas must be kept very clean and as free of manure as possible. A cow should never give birth in a dirty pen. Use lots of clean bedding to reduce the risk of illness or infection. Fresh bedding reduces exposure even before the dam has a chance to lick off the calf. Newborn calves should never nurse a cow with a dirty or mature-laden udder, as passage of E coli is too great for their immune defenses.

If weather is severely cold, you can get by without cleaning stalls if you put clean bedding on top for each new cow. The build-up of bedding can keep barns warmer in sub-zero temperatures. Using good sanitation principles and basic hygiene aids in the prevention of sickness and possible mortality due to organisms such as E coli, Mycobacterium or Salmonella.

Comfort: Newborn calves need to be kept comfortable and provided with plenty of dry bedding and shelter from drafts and wind in cold weather. This factor is especially important during severe weather as it stresses the body by requiring energy for heat production. Below 20 degrees F, ears and tails may freeze and the calf’s mouth may become too cold to nurse. The increased demand for energy can keep a calf from gaining weight during these months unless they are protected. Simple windbreaks can be adequate for calves that are not yet ready to venture into the pasture. Calf coats can help maintain a calf’s body heat by providing protection from the wind and cold. Weaned calves do not need additional care however breeders must ensure the presence of adequate feed and an ice-free water supply.

Consistency: Consistency of newborn protocols and daily calf management is important. Calves should be provided with regular supplemental feedings in the form of grain and hay. (Hay should be dry and not first cutting or pure alfalfa to prevent digestive upset.) The same person who performs routine feedings and care should observe calves at the same times every day. Changes in the routine will stress calves, and animals that are stressed are more likely to get sick. Healthy calves correspond to happy breeders. More importantly, a quality product is worthy of economic value and a source of pride for a job well done. Happy Calving!

Exactly What is a Miniature Hereford?

EXACTLY WHAT IS A MINIATURE HEREFORD

There’s a lot of misunderstanding being perpetrated regarding the classification of Miniature Herefords, making them out to be a separate breed, which they are not. This is causing unnecessary confusion among new owners and potential breeders. Quite simply the animal is a Hereford first by breed and a miniature second by size. A look at some of the terminology which has been used incorrectly will show this.

Firstly, there is no such thing as a “purebred” Miniature Hereford. The description should be “full-blood Hereford” without any reference to the miniature size. A full-blood animal is one which has no other breed in its background going back many generations. In the case of Herefords this goes back several hundred years. A Hereford bred to another Hereford, regardless of size is still a full-blood Hereford. The only differentiations which can be made with Herefords are whether they are horned or polled or of different sizes e.g. standard, classic or miniature but those are just varieties of the same breed.

“Purebred” is the result of successive back breeding from original crossbreeding or interbreeding and this applies to using two or more entirely separate breeds. In this way we now have recognised breeds such as Belgian Blue, which was developed from native Belgian cattle crossed with Shorthorn and Charolais. The Australian Belmont Red is another example of crossing or interbreeding, in this case Africander bulls over Hereford and Shorthorn cows. Purebred usually means a minimum 31/32 cattle which have been produced through a “grading up” process from the original breeds used.

“Crossbreeding” or “interbreeding” is exactly that – the mixing of different breeds. You cannot crossbreed or interbreed within the same breed. Therefore, the practice of referring to a Miniature Hereford with Classic or Standard Hereford in its pedigree as a crossbreed is totally untrue. All Miniature Herefords have this mixture of sizes (not breeds) in their pedigrees. A Brahman crossed with a Hereford produces a crossbreed known as a Braford – two separate breeds. Likewise a Brahman crossed with an Angus produces a Brangus. The popular Murray Grey is a result of crossing an Angus with a Shorthorn and refining the breed over many generations. Another interesting combination of breeds leads to the Mandalong Special which has Brahman, Shorthorn, Charolais, British White and Chianina in its background.

“Grading up” again applies to using more than one breed to combine particular genetics. It starts with using a bull from one breed with a cow of another breed. The first offspring is half-bred and heifers from this are then bred back to the original bull breed. The next offspring will be three-quarter bred and the procedure is repeated using part-bred heifers back to the original bull breed until offspring which are of 31/32 breeding are then classified as “purebred.” They are not full blood of either breed used. The “grading up” being used within the Hereford breed to produce a so-called fifth generation miniature is not justifiable as it is simply using two animals of different varieties of the same breed and the final outcome may not necessarily fall within miniature status as the frame score size could well be over the limit. The original process of acquiring miniatures was to breed the smallest Herefords possible to other small Herefords and continue from there to reduce the size, not to establish so many generations of breeding. Frame score can be heritable and changed mainly through using selected sires. Therefore, it is more important to know the frame score background of the animals being bred than their pedigrees.

“Inbreeding” along with “linebreeding” is now prevalent among Miniature Hereford herds in both Australia and New Zealand owing to the lack of new bloodlines. Although one advantage is the early exposure of a defect, providing measures are taken to eradicate that, the main outcome is a loss of fertility along with detrimental effects on production efficiency. Inbreeding is computed as a percentage of chances for two alleles to be identical by descent. This percentage is called “inbreeding co-efficient.” Alleles are alternative forms of genes and part of the DNA coding which determines distinct traits which are passed on from parents to offspring. Progeny can have a 1 in 2 risk of inheriting identical alleles from both parents which greatly increases any negative effects. Linebreeding is a milder form of inbreeding through breeding of cousins. Anyone claiming to have “five generations” of “miniature” in an animal should properly examine its breeding; it is most likely the product of straight inbreeding or very close linebreeding, neither of which is desirable. For this reason conscientious breeders in other parts of the world occasionally introduce new bloodlines using mainly the smaller Classic Herefords which are of FS 2 or FS 3. This is known as “outbreeding” but it is still within the same breed.

In Australia and New Zealand there are Classic sized animals among the standard Hereford herds that are not actually classified as such. A miniature bull (FS 1 or less) over a Classic cow should produce progeny not much bigger than themselves.

Much has been made of a “foundation herd” and a claim that all Miniature Herefords in Australia and any animals coming to New Zealand from Australia must be linked to this. The foundation herd is nothing more than a collection of original imports from the USA most of which had a Classic Hereford in the immediate parentage. There is at least one animal classed as “miniature” which had Classics for both parents. How did the classification of “miniature” arise then? It could only have been on frame score as most of the Classics were FS 2 or 3. Was FS 2 considered “miniature”? It certainly wasn’t in the States. To restrict the classification as “miniature” to only particular animals whose pedigree traces back to chosen “ancestors” is not only irrelevant, it drastically narrows the gene pool and constitutes restrictive trading practice for other breeders who have animals which qualify by size, the only criteria needed. These latter animals are likely to have superior genetics through a widened gene pool and as such strengthen the overall breeding of Miniature Herefords.

Finally, to state that animals must be classified as “miniature” by only one particular group is an insult to the majority of breeders. The integrity of the breeder in noting the size of an animal goes hand in hand with the integrity of the breeder in stating the correct parentage. If the intending purchaser has any concerns, a request can be made for a DNA profile, the registration checked and the measurement process observed or done independently to confirm what has been stated. As it stands now, no group is the authoritative body for classification of Miniature Herefords. ly one particular group is an insult to the majority of breeders. The integrity of the breeder in noting the si

Beef Talk: Simple Bull Rankings in the Pen

Report Card for 8 Red Angus Bulls

Does the data support keeping them, or are there better bulls on the market that will meet your production goals?
By Kris Ringwall, Beef Specialist

NDSU Extension Service

The Dickinson Research Extension Center utilizes many bulls and always evaluates bulls at the time of purchase and periodically throughout their life span. Perhaps the most challenging evaluation is to ask if the bulls meet the current objectives of the breeding program or expected market for the calves.

Many good beef programs remain as words only if the right genetics is not in the bull pen to get the desired calf crop.

For the center, the heifer development program is being scaled back, which means the current inventory of calving-ease heifer bulls was reduced. In terms of future programs, the center has two different needs.

The first is for bulls that will sire heavy-muscled calves with a reduced frame and a slightly slower growth rate. These calves obviously will end up on a grass program and are projected to go to an older yearling market.

The second group of bulls will need to sire calves for the traditional fast-gaining, high-lean calf- fed market. These calves will be age and sourced for the less than 20 month of age calf market.

However, before either of these criteria can be discussed, the older bulls need to be evaluated based on soundness. Unsound bulls are not kept because putting more resources into a bull that more than likely will have limited breeding capacity is impractical.

Producers should evaluate their bulls periodically, especially when the bulls are penned where they can be observed closely. That slow-moving, standoffish bull may be covering up latent pasture injuries or fresh injuries due to the rough crowd in the bull pen.

The harsh reality is that small problems tend to become big problems. Even minor structural problems often will develop into movement problems during future breeding seasons.

The pecking order also can get severe enough that some bulls simply won’t breed. The old saying that “an ounce of prevention is worth a pound of cure” applies now because the time to be thinking about next spring’s breeding soundness exams is now.

With the cold weather setting in, the best prevention for bull infertility is a well-bedded bull pen with limited exposure to the wind. Bulls need to be bedded and protected from severe cold to prevent scrotal frostbite.

After the review, only 10 bulls made the cut for next season. Two are Lowline bulls, while the others are Red Angus. All of the Red Angus bulls are registered with the American Red Angus Association and the registrations and data are current. Everyone is busy, so keeping up on the bull pen is not easy, but all the bulls are in good physical condition.

The bottom line is that the remaining bulls have a purpose, which is to fill the weaning pens in the fall of 2011 with the calves that the center desires. Seems like a long way off, but the calves will get here soon enough.

All the bulls were rated for some of the expected progeny differences (EPD) available from the Red Angus Association. The challenge with data is information overload. The information available on sale day was impressive enough to buy on sale day or the bulls were simply affordable. The question is, “Are they still good enough to stay or are there better bulls?” To make the process simple, the bulls are ranked and scored based on the desired EPDs.

If the bull scores in the upper 25 percentile within the breed for a specific EPD trait, the bull received an A. If the EPD value is in the upper 50 percentile, but less than the 25 percentile, the bull received a B grade. If the bull’s EPD value was in the lower 50 percentile, the bull received a C grade.

Having gone through the exercise, eight bulls passed the center’s needs, while the rest did not. In summation, the bull pen has eight good, meaty Red Angus bulls that vary in frame size. With the bull-buying season starting early next year, the center can better evaluate how many bulls are needed and, like any producer, can develop a budget to work with.

The process may seem cumbersome, but the take-home point is to gather some data and rank the bulls. Does the data support keeping them, or are there better bulls on the market that will meet your production goals? These are your cattle, so you need to become comfortable working the numbers and incorporating data into your decisions to ultimately meet your goal.

Happy bull sorting and turkey eating.

May you find all your ear tags.

Bulls Eye: A Winning Calf

Danielle Riley from Cedar, Kansas
received Reserve Champion in her
class at the 2010 Smith County
Fair with an Angus/Mini Hereford cross
steer.
Bulls Eye was born on 3/17/09. His
momma was a big black Angus cow that
calved late the year before. We used Hugo, a Miniature Hereford bull, on
all of our late calvers and for clean-up at the end of the breeding season,
so we had about half a dozen Angus/Mini Hereford crosses. Bulls Eye has
a crazy freeze brand looking mark on his left front shoulder that Dani
wished would have been on his “show side.” He was an average size calf
when he was born and was pretty square and boxy looking from day 1.
The girls immediately took a liking to him.
At weigh-in on July 16, 2010 he weighed 1188 pounds and was the
lightest calf in his class, but was definitely the most finished. Hugo’s mini
features really popped in Bulls Eye in the last 60 days, from his nice wide
frame to his full brisket. The combination of that and his momma’s tall
and long lines were perfect to receive Reserve Champion in his class. We
fed him Honor Show Chow from Pro Ag in Kensington, Kansas. Bulls
Eye sold for the maximum price at the premium auction, $1,042.00 over
market price.
This is Danielle’s 4th year in 4-H and 4th year in the beef project. She
already has a mini Hereford/Angus cross calf picked out for next year. Dani
and little sister Matti both like the same calf, so hopefully there will be a
couple Angus/Mini Hereford cross calves at next year’s Smith County Fair.

MHBA Animal Health Series

Bang’s disease or Brucellosis is caused by the organism brucella abortus and is spread from the vaginal discharge of an infected cow or from an aborted fetus. Brucellosis or “contagious abortion” causes abortion and premature births in cattle usually between the fifth and eight month of gestation. The infection is concentrated in the reproductive organs of the animal where it localizes in the uterus, udder and placenta of the female and testicles of the male. The disease can cause “undulant fever” in humans through the intake of infected milk. While the occurrence has been drastically reduced in modern times due to aggressive vaccination programs, failure to meet the window of opportunity can have devastating consequences for a uniformed or unsuspecting buyer. Bangs vaccinations are required by most states but not all as most are able to maintain the status designated as “Brucellosis Free.” Although state and federal regulations have helped to control the disease, there is still a threat.
Humans can become infected with the bacteria by either eating or drinking something contaminated with Brucella, breathing in the organism or having the the organism enter through a skin wound. While ingestion is the most common source of the contamination, hunters and butchers may be infected through skin wounds or by accidental ingestion of the bacteria after cleaning deer, Elk, Moose, or wild pigs. Encounters with infected herds of wild game remain the primary reason for continuation of a regulated vaccination program.
States having the vaccination requirement also have established timeframes for delivery. Most including, California mandate the vaccination be provided to females between the ages of 4-12 months. This vaccination must be given by a licensed veterinary and appropriate documentation including a numbered ear tattoo is required.

Symptoms and Transmission:
• Abortions, retained placenta, weak calves and infertility frequently occurs
• Milk produced by an infected cow may also be contaminated with the organism
• The organism is usually transmitted orally but can penetrate unbroken skin or drainage from an infected eye
• Breeding bulls which are infected, can transmit the disease to cows at the time of service by infected semen
• Infected animals are slaughtered, infected herds quarantined, and carrier animals identified and traced back to their place or origin.

Recovery, Testing and Infected Animals:
• There is no treatment for Brucellosis
• Diagnosis is made by a blood test of the dam and examination of the fetus
• Some degree of immunity as animals that abort can conceive again and carry the fetuses to term, although the disease remains in a latent form and the infected animal remains a source of infection for others
• Infected animals are slaughtered, infected herds quarantined, and carrier animals identified and traced back to their place of origin
• Buy replacement animals only from a clean herd, have aborted fetuses checked.

As there is no treatment for Brucellosis, the main source of prevention is accomplished by official calf hood vaccinations of heifer calves. An accredited veterinarian must provide these vaccinations at calf ages of two-four months with standard dosage vaccine, or from four to twelve months using reduced dosage vaccine. Each calf must be identified by an official vaccination in compliance with state and federal regulations. Quarantines are imposed on infected herds by state and federal authorities until the heard has been proven free of the disease.
When it comes to the Bang’s vaccination, it is Breeder and Buyer beware. Never buy a heifer without an appropriate state regulated vaccination, documentation and accompanying ear tag. Breeders should never sell a female without providing proof of Bang’s vaccination. In our state, females over the age of 12 months can never be vaccinated; therefore, they can never be exposed to other animals through shows or sales. Animals vaccinated after this age usually test positive thus requiring the whole herd to be quarantined; therefore be a responsible breeder and vaccinate your animals prior to their first birthday.

Smaller-framed Cows

Smaller-framed Cows May Help Contain Input Costs
By SUE ROESLER, for The Prairie Star, reprinted with permission.
Sunday, August 1, 2010 3:25 PM MDT

Cows and their calves are different sizes here in Mandan, ND but ARS research is aiming for a smaller-framed cow herd.
“Grazing as long as possible in the Winter and having a smaller-framed cow herd that eats less are some of the ways that may help keep input costs low and ranches profitable,” says Dr. Scott Kronberg, an ARS research range scientist with an animal focus. “A lot of us think it will cost more to feed cattle in the future,” Kronberg said as he explained that oil has a trickle down effect and other prices tend to be tied in with oil. “As oil prices rise, other costs such as fertilizer and fuel to run farm equipment, also rises. When it comes to a choice between driving their cars or paying high prices for beef, consumers are more likely to buy cheaper cuts of beef and continue to drive,” Kronberg said. For some, beef may even be a luxury if it is unaffordable.

So for producers to stay profitable in the future, they have to be able to break-even and continue to have an efficient operation when cattle prices are low. “Then they can be really profitable when prices are high,” he said.

Kronberg was one of several speakers on the crop tour at the USDA-ARS Northern Great Plains Research Laboratory’s annual Friends and Neighbors Day in Mandan, ND. “There are a lot of ways to cut the cost of livestock production and still be productive,” Kronberg said. “We’re looking at grazing more and feeding less. If I could graze all year I would,” he said.

Kronberg said even in heavy snow, cows will eat the grass sticking up through the snow. They grew Altai wild rye, which grows very tall, and allowed the cow herd to graze well into January. If the snow is just too high, they can supplement when needed. He said he is just building a smaller-framed cow herd to base his research on, and wants cows to be smaller and thicker, in the 1,100 pound range producing calves who are 500 to 600 pounds by the end of October.

“It might seem a little different to raise smaller cows. It is probably not what your neighbors are doing. But these smaller-framed cows are really efficient and live a long time,” Kronberg said. In addition, he wants cows that will produce a “nice calf” for 20 years. At the ARS ranch, they calve in May instead of March. The reason is so the calves will not become bigger cows who could end up in their last trimester in the Winter and need a higher-quality feed for good nutrition.

“A lot of producers really don’t know how much their cows weigh because they don’t weigh them,” he said. Instead, an average of the cattle is usually obtained when cattle are weighed in bulks of about 10 at a feedlot. He challenged the crowd to guess the weight of three Angus cows who gathered in front of an electric fence with their Spring calves. “There really isn’t a cow here who is one I’m looking for yet,” he said.

Cow #1 was the largest of the three and weighed 1,483. “She is a pretty common size for cattle in many regions up here,” Kronberg said. Last year, the cow weaned a heifer calf that was 472 lbs. on April 20. This year, her calf was 76 lbs. at birth. Cow #2 was 1,280 lbs. and weaned a bull calf that was 520 lbs. in October. This year, she gave birth to a 86-pound calf on May 12. Cow #3 weighed 1,005. The calf size was not given.

While Kronberg does not know for sure that smaller-framed cows will eat less and still be efficient, his research is focusing on that. “If you have a cow that has to be culled in year eight because of no calf, that is not efficient to your cattle production because it costs a lot to bring her into the herd,” he said.

Range scientists in Miles City, MT have devised a new method of determining exactly how much forage grazing calves are consuming. It does not involve inserting a cannula into the calf. “We can’t look at production efficiencies until we know what goes into the feeding expense everyday,” he said.

Winter feeding is usually the most expensive feed for producers if cattle are kept in a feedlot or in the yard. In addition, if cows are in their third trimester, feeding a lot of hay is expensive. Smaller cows that calve in late Spring or Summer would not run into that problem. “If we can graze well into the Winter, the costs go way down,” he said.

Vern Anderson, livestock specialist at Carrington, ND Research Extension Center, asked how land prices fit into the schematic. Kronberg agreed that if a producer owns his own land, costs can be contained better.

Minis 101: Selecting Your First Purchase

Minis 101: Selecting Your First Purchase

There are many variables to consider when you consider purchasing your first Miniature Hereford. First, you need to decide for what purpose you wish to raise Minis. Secondly, you need to determine the size and quality needed for that purpose. Then you will spend many hours researching various options for acquiring the type of animal you’ve selected, and finally you’ll realize your dream by hauling that special animal or group of animals home.

So why do you want to raise Miniature Herefords? For the kids? Grandkids? For cute lawnmowers in that enormous back yard you’re sick of mowing and fertilizing every summer? What about agricultural tax breaks in your area? Do you want the option of healthy beef for your family? Or maybe you want to shoot for that coveted Grand Champion buckle? Answering these questions will help determine what type of Miniature Hereford would best suit your needs.

If you’re looking for an animal that will do well with youngsters, you might want to consider one that is already halterbroken, and is known to be gentle around children. In this instance, and finances aside, the smallest animal you can find who still meets the temperament requirements would be your best choice, for the sake of safety. Depending on whether or not you wish to encourage your kids to show in 4H, FFA or in the Open shows – you might consider leaning toward a show-quality purchase versus pet-quality.

However, if you’re merely looking for a lawncare replacement, size is most likely not your primary concern; you would research calving ease of the animals and units-per-acre in your area to determine the number of head needed to properly “mow and fertilize” your property with as little intervention as possible.

Agricultural tax breaks are a common reason for investing in Miniature Herefords. In some areas of the country, the cost of purchasing the cattle is more than repaid within a few short years. These laws vary from state to state and county to county so be sure to check the regulations for your area.

Another common reason to invest in Miniature Herefords is for the beef. Miniature cattle do not fit the model for today’s beef production system, so do not expect to sell your cattle the “normal” way for any profit. Instead, you have the option of raising organic, grass-fed or natural beef for your family, friends or community members. The simplest method would be to raise beef for your family alone. Have it processed locally or process it yourself and you can provide for your family great-tasting beef that is far superior to even the highest grade grocery store beef. If you choose to label your beef and sell it, be sure to study the rules and regulations regarding the sale of meats, and the special labeling required.

If you wish to raise Miniature Herefords specifically for the show ring, be sure to obtain the best that money can buy and care for them extra specially well. Of course, we can’t all purchase last year’s grand champion in the hopes she’ll win again this year! So purchase the best animal you can find, remembering that price doesn’t always indicate quality. A well conditioned animal, exquisitely fitted and properly shown will still provide an excellent chance at that banner or buckle, and at the very least you’ll have lots of fun in the process.

Once you’ve determined what your purpose is, or which combination of goals you wish to pursue in the Miniature Hereford adventure, you’ll be able to rule out types of animals that are less likely to suit your agenda. The smaller the frame score (size) of the animal, or the more 0’s they’re said to have, the more expensive they will be. This is because 0000 is the smallest anyone has in any quantity. Try looking for a 00000 animal and you’re going to be searching for a while. You’d better be prepared to write a lot of 0’s on that check if you choose to purchase that animal, if you find him. On the other hand, there are many mid-sized Minis in the frame score 0 to 1 range and you’ll have a far wider selection of type and quality. What size and quality you eventually choose is up to you, your goals, your pocket book, and what is available when you’re ready to buy.

So you’ve now decided on the type of animal that will best suit your needs. How far are you willing to to travel to find this animal? Begin by locating breeders in your area, and if possible, go to see their breeding program in operation. Expand your search as necessary. Whatever you do, be sure you’re working with a reputable breeder when you finally choose to purchase. Common pitfalls are paying show-quality price for a pet-quality animal (so study up on your conformation points, visit shows and don’t hesitate to quiz breeders or your Regional Director) or paying top dollar for a small framed animal only to discover she’s not genetically small framed and won’t produce in kind (so study up on those pedigrees, sire/dam frame scores, and obtain references on prospective breeder-sellers). The more you’ve studied, the better your chances of arriving home with your dream cow.

Remember while shopping that somehow you’ll have to cart your acquisition home. If you have a trailer, no worries. If you don’t, ask the seller if they’ll deliver. And if they can’t or won’t, call your Regional Director to find out if there are any breeders currently hauling who might be able to help you out. Definitely solve the transportation logistics before handing over that down payment.

Whatever your path to first-time ownership, there is nothing quite like opening your trailer door and watching your new red white-face hop out of the trailer and trot down the fence line examining her new surroundings.

Welcome to the world of Miniature Herefords!

Heat Stress

HEAT STRESS CAN REDUCE PREGNANCY RATES
audio/video clip of this topic
The effects of heat stress on reproductive performance of beef cows has been discussed by many animal scientists in a variety of ways. After reviewing the scientific literature available up to 1979, one scientist wrote that the most serious seasonal variation in reproductive performance was associated with high ambient temperatures and humidity. He further pointed out that pregnancy rates and subsequent calving rates were reduced from 10% to 25% in cows bred in July through September.
Typical Oklahoma summer weather can fit the description of potential heat stress, where many days in a row can exceed 95 degrees and night time lows are often close to 80 degrees. Many hours of the day can be quite hot and cause the slightest rise in body temperature of cattle. Research conducted several years ago at OSU illustrated the possible impact of heat stress of beef cows on their reproductive capability. These cows were exposed to bulls as one group (while in a thermoneutral environment) and one week later exposed to the environmental treatments listed below in Table 1.

Table 1. Effects of Imposed Heat Stress on Reproduction in Beef Cows
(Biggers, 1986;OSU)
Treatment group/ Control/ Moderate Stress /Severe Stress
Daytime temp (F)/ 71/ 97/ 98
Nighttime temp (F)/ 71/ 91/ 91
Relative Humiditiy %/ 25/ 27/ 40
Rectal temp (F) /102.0/ 102.7 /103.6
Pregnancy %/ 83/ 64/ 50
Conceptus Weight (g) 0.158 0.111 0.073
They found that heat stress of beef cows from day 8 through 16 affected the weights of the conceptus (embryo, fluids, and membranes) and the increased body temperature may have formed an unfavorable environment for embryo survival. As noted in table 1, the percentage of pregnancies maintained throughout the week of severe heat stress was considerably reduced.

Florida scientists studying dairy cows reported that for high conception rates the temperature at insemination and the day after insemination was critical to success. They stated that the optimal temperature range was between 50 degrees F. and 73 degrees F. Marked declines in conception occurred when temperatures did not fall in this range.

Beef producers conducting Artificial Insemination or Embryo Transfer may want to take heed of this information. Make certain that cows are allowed access to shade and adequate air movement, at breeding, and immediately following breeding. Of course, adequate cool water is important anytime during the summer months. Avoid forcing recently inseminated cows to stand in treeless, drylot situations where relief from the Oklahoma heat is impossible.

Minis for the Whole Family

My interest in miniature Hereford cattle started a long time ago. My husband and I stopped at a sale barn in Macon Missouri in April of 1998. Just to see what they had, and what a sale. There were elk, Watusi, Zebu, Dexter and even Miniature Herefords. We watched for a while and then out walked a couple with a pair of miniature Herefords. A bull and a heifer. I thought they were the neatest things I had ever seen. I don’t recall ever seeing miniature cattle before. I have always liked the Hereford breed. Come to find out later, it was Ken and Ali Peterson who had the pair.
Then in 2005 there was an article in the Farm World magazine about a girl showing her miniature Hereford steer at the Indiana State Fair. She had to show against the big ones, because there was no class for the miniatures. She said the judge just kept telling her it was too small. Even though it was fed out. Judges just didn’t understand at that time. But Indiana has never had a class for miniatures as of now .
My husband passed away in 2006. After that I had more time on my hands and I started to look for some miniatures. I went on line and printed out a list of owners. Then
I just started calling. I was looking for some polled heifers and a steer. I found some right here in Indiana and went to see them. I purchased two heifers and a steer in Dec.2007. My son was with me and he purchased a heifer too. His heifer went to the Denver Show and was named the reserve champion fall Jr. miniature Hereford.
Then my grandson got interested and he purchased two heifers from Illinois. That gave us a total of five which was enough to make a class at our county fair. My grandchildren showed all five in 2008. We were really busy, having done this for the first time. My idea was to get the miniatures started on the local level, then maybe it would get started on the state level.
I had to wait until I was 73 years old to get to show cattle. I had always wanted to.
We have shown some at the Farm World Show in Lebanon, the NAILE in
Louisville twice, Iowa St. fair and again in our county 4-H fair.
We now have a total of sixteen including a bull that I purchased. The herd is expanding pretty fast. This spring we had four heifers and one bull calf. Pretty lucky I think.
I don’t have any fancy buildings or anything like that. My barn for the cattle is an old
Garage that we had moved to make room for a new garage. But it works.
I really love my miniatures. I like working with them, they are so gentle. I would rather be working with them as anything else.
I have met a lot of really nice people in this organization. They are my inspiration.

MHBA ANIMAL HEALTH SERIES
Summertime in Cattle Country

By Peggy Joseph-Potter RN, BSN, MHA

Summer, a time fun, family, fairs and if you raise cattle the challenge brought on by heat, flies, pinkeye and parasites. While we may live in different climates with varying levels of humidity, the stress brought to cattle by this warm weather onslaught is universal.

Heat stress can cause reduced productivity in cattle, the more severe the stress the more detrimental the effects are on performance. Reduction in reproductive ability, daily weight gain and reduced milk production are the main outcomes of this form of stress. Cattle are more sensitive to heat than humans are. Heat stress is a combination of temperature, relative humidity and wind speed. Other factors such as age, hair coat length, hair coat color and nutritional status all play a role in determining the severity of heat stress on your herd. Breeders need to watch their cattle, the environment and be familiar with the signs of heat stress.
Signs of Heat Stress:
•Restlessness and crowding under shade or at water tanks.
•Open-mouthed breathing (panting), and increased salivating.
•Increased respiration rates, (Moderate heat stress: 80 to 120 breaths per minute, Strong heat stress: 120 to 160 breaths per minute. Severe heat stress: over 160.)
•Gasping and lethargic.
The symptoms of heat stress may often present in the same manner as respiratory disease. Cattle do not sweat; therefore, they must use their respiratory system to eliminate excess heat from their bodies.
Heat stress interventions:
Provide ample water. Cattle may need more than 2 gallons of water per 100 pounds of body weight. Provide enough tanks for cattle to be able to get the water they need. If possible, water should be cooled and placed in a shaded area; tanks should be cleaned weekly to encourage water consumption.
Avoid handling cattle. Handling cattle can elevate their body temperature by as much as 3.5 degrees F. If cattle must be worked on hot days, try to do the work before 8:00 AM and keep the maximum time in the holding facilities to no more than 30 minutes
Change feeding schedules. On hot days, shift your feeding times toward the evening hours. Try to deliver 70% of the daily scheduled feed two to four hours after the peak air temperature. Providing only small amounts of feed during the heat of the day, will decrease the metabolic heat of digestion.
Provide shade and improve airflow. Shade can come in the form of trees or it can be constructed. Solid, reflective covering is preferable to slats or other more open forms of overhead roofing. When possible, two shaded areas are recommended, one over the feed area to increase feeding time, and another away from the feed area to encourage the cattle to rest. Water should be made available under both shaded areas, to increase the water consumption during heat stress period. Consider where the cattle are located and if there is any restriction to air flow. Box or barn fans provide increased circulation and when combined with a mister can decrease temperatures in barns and stalls.
Provide water mist. Providing a spray of water will help to cool the animals down. However, it is important to place misters over a clean, preferably concrete area. Misters should not be over dirt or allowed to create pooling or mud puddles, which increases the incidence of bacteria and flies. When possible, use a timer, this will allow cooling without getting the cattle wet
Fly Control:
The control of breeding flies is necessary to assure adequate animal health, rate of gain and to maintain weaning weights. There are two major species of flies that cause the most serious decreased in beef production and require the most control efforts, they are the horn fly and the face fly. Horn flies cause the economic loss for cattle breeders through blood loss and irritation. The reduction in weight gain can be as much as 10-14%
The adult horn fly, which is about one-half the size of a housefly, has piercing/ sucking mouthparts and feeds on blood and tissue fluids of cattle. They spend most of their adult life on cattle and feed 20 to 40 times a day. They are normally found on the animal’s back, but may migrate to the sides and the belly as the temperatures increase. The fact that they spend the majority of their time on the animal’s body makes them much easier to control.
The face fly is about the size of a housefly. They are non-biting, feed on secretions from the eyes, and muzzle. They avoid entering dark places, such as a barn, while on the animal. The female lays eggs on freshly deposited manure like the horn fly; however, unlike the horn fly they are present on cattle only about 10 percent of the time and may be found resting on fence posts, trees, bushes and other objects the other 90 percent of the time. Because they spend so little time on the animal and do not feed on blood, they are much harder to control than horn flies.
There are several methods of fly control, such as insecticide sprays dusts, pour-ons, oilers, dust bags, ear tags, oral larvicides in minerals and blocks and controlled release boluses. All of these methods are effective and have a place in the control program; however, the best fly control can most likely be obtained through an integrated fly control program.
Back rubbers and dust bags are effective and can be placed at gate openings. Insecticide-impregnated ear tags are easy and should be placed at the beginning of the season and removed in the fall. Make sure you fully protect your weaing calves with a pour-on and ear tags for the best coverage. Remember to rotate your insecticides to prevent the development of resistance and an overall decrease the program effectiveness. Organophosphates and pyrethroids are normally alternated based on their effectiveness against flies specific for that region.
Parasites:
Summer is the time to step up your parasite control program. Many of the products and methods used for fly control are also effective against internal and external parasites. Insectide tags, oral lavicides added to mineral blocks and mixes aid in the elimination of parasites from surfaces and manure. Dust bags and sprays are good for control only if used regularly. As with fly control, the best coverage is gained by a combination of methods and products.
Remember the accumulation of water or manure is a prime breeding ground for flies and other parasites. Consult you ranch veterinarian or local Ag extension for the products most effective in your region.
Pink Eye-Moraxella bovis:
Pink eye (moraxella bovis bacterial infection of the eye) in cattle can result in serious economic losses, through poor weight gain, eye damage and even blindness, if left untreated. It is highly contagious and is spread by face flies as they feed on the secretions from the eyes. Early treatment is most effective, the use of ointments, sprays and powders must be performed twice per day and this requires the eye to be protected against sunlight or further irritation from flies, dust and foreign objects with an eye shield. The administration of 1 ml Penicillin given under the eyelid in two places is usually effective enough for one treatment.
Symptoms of Pinkeye vary from watering and drainage of the eye in the early stages to a cloudy discoloratation or even ulcerations of the cornea in the latent phase. Early treatment is necessary to prevent advancement of the disease and prevent permanent damage.
Newer treatments such as the use of Veterycin VF TM are also very effective if started at the onset of symptoms. It is much less caustic, painful, and irritating to the animal than other treatments. Our personal experience with this product has been very good and we use it as a first line drug in the treatment of any bacterial, fungal, viral or spore forming infection. Its non-irritating formula makes it a great all purpose as a wound cleanser as well.
Summer is a great time to enjoy your animals so keep them healthy by being prepared. Purchase your ear tags, dust bags and sprays early. Combine these activities with pour-ons, vaccinations and other possible heat producing events early in the day. Diminish pest breeding grounds by ensuring your pens are free of standing water and accumulate manure. Healthy Herefords make for happy breeders, so be prepared and start early to assure your programs effectiveness.

Invest in Fly Control

MT. VERNON, Mo. — Think how much aggravation 200 flies biting and flying around you would create. No wonder research shows that blood-sucking horn flies can reduce calf weaning weights by up to 20 pounds and reduce gains on stocker cattle by 25 pounds per head when flies are not controlled.

The threshold level for economical fly control begins around 200 flies per animal according to Eldon Cole, a livestock specialist with University of Missouri Extension.

“Counting flies isn’t easy so most of the estimates are made using the assumption that if there’s an area of flies on the animal the size of the palm of your hand that’s roughly 50 flies,” said Cole. “I’ve assisted with a field trial that involved using binoculars and actually counting flies early in the season when they weren’t too numerous and it is easy to get 200 flies per animal.”

In addition to horn flies, horse flies, stable flies and face flies may create problems for cattle as the summer goes on. Each of these creates a unique problem for animals and are difficult to control according to Cole.

“The routine control measures for horn flies will only have limited success with the other fly species,” said Cole.

Sprays, insecticidal ear tags, dust bags, back rubbers, pour-ons and oral larvacides are the controls used on horn flies.

“There is even research supporting biological control with fly predators, but they work mainly in densely populated cattle areas such as feedlots,” said Cole.

Another interesting point in cattle fly control is that some animals seem to be less susceptible to flies than others. Researchers are looking at this from the cattle’s genetic resistance standpoint. It could involve hair density, hair color, sex of the animal, hide thickness, etc.

“As you work with your herd you may observe that some cattle attract more or significantly fewer flies than others,” said Cole. “Most of the fly control methods for horn flies do work. However, cost, convenience and length of control must be considered.”

For more information on fly control in beef cattle, check out the Missouri Beef Resource web site at http://agebb.missouri.edu/beef/index.htm. Three MU Extension livestock specialists are also available in southwest Missouri and can be reached by telephone: Eldon Cole in Mt. Vernon, (417) 466-3102, Gary Naylor in Dallas County, (417) 345-7551, and Dona Geode, in Cedar County, (417) 276-3313.

SIDEBAR:

Deciding Which Horn Fly Control Measure is Best for you

Eldon Cole, a livestock specialist with University of Missouri Extension, says there are several things to keep in mind when deciding which horn fly control measure it best. Keep the following items in mind:

* Resistance to pesticides can develop so rotating each year or so between the pyrethroids and the organophosphates will help slow down the resistance buildup.
* Remove old fly tags at the end of their useful life. Leaving them in aids in fly resistance buildup.
* Many fly tags are still effective, but frequently are put in too early in the season. Rotate the active ingredient used in the tag from year-to-year.
* Backrubbers or dust bags are highly effective and economical, but they require regular management to make sure cattle use them.
* If you’re fortunate enough to have a supply of wire and burlap bags you can make your own rubber at a significant savings. Old flannel material will work in place of burlap.
* Feed-throughs offer convenience, but cost more per day or month. They are most effective when consumed by all cattle in a fairly large area. The additive interrupts the life cycle of the horn fly in the manure pat.
* Combining horn fly control tactics may be helpful to give the cattle maximum relief. Remember you’ll never have totally fly-free cattle.
* Face flies are generally not resistant to pesticides and insecticidal ear tags and other control methods for horn flies are effective against them.
* Treatment costs per head per day can vary from a couple of cents up to 8 to 10 cents depending on method and expected length of effectiveness.

For persons not wanting to use pesticides, University of Missouri Extension does have plans for a walk-through fly trap (that reduces flies up to 70 percent) that can be located where cattle pass through it daily. Ask the nearest MU Extension Center for guide sheet 1195 or find it online at extension.missouri.edu.

“Ag Exempt” Status

These days it seems that taxes of every kind are on the rise, regardless of where you live, so it is not surprising that people are looking for ways to reduce their tax liabilities. While tax codes vary greatly from state to state and even county to county, here in Texas, many people are looking at Miniature Herefords as a way to gain or maintain an “Ag Exemption” on their property. These tax exemptions have become especially important as the sprawling ranches and farm lands are replaced with urban development and smaller acreage “ranchettes”. This “Ag Exemption” may result in a significantly lower property tax bill each year based on certain land use requirements but there are some factors one must consider (and stiff penalties!).

DOES MY PROPERTY QUALIFY?
The most common “Ag Exemption” in Texas is actually not an agricultural exemption per say, but rather an exemption based on the ‘Open-space Appraisal 1-d-1’. This land appraisal method has three primary requirements:
the land must be primarily dedicated to agricultural use consistent with generally accepted practices in the area (relatively broad)
during 5 of the preceding 7 years, the land has been dedicated to agricultural, timber or forest production
the necessary form(s) must be provided to the appraisal office prior to May 1 for evaluation
The key word in the “Open-space Appraisal” method is agricultural USE. This can be defined as crop planting/production, raising livestock or exotic animals, wildlife management or land devoted to horticulture type use. With this type of exemption, the landowner’s primary business or occupation is not a factor, as the primary purpose of the exemption to preserve open space.

In Montgomery County, Texas, the minimum acreage requirements can vary based on the use, density, etc but when it comes to raising livestock, 20 acres is the minimum required for an exemption. The number of livestock head required varies (depending on type, breed, etc) and should be determined with your appraiser. However, one of the many attractions to raising Miniature Herefords is their efficiency (and easy keeping!) makes this type of exemption extremely viable on smaller acreage.

While commonly referred to as an “ag exemption”, the open-space appraisal differs greatly from a true “agricultural exemption” which is known as ‘Agricultural Use Appraisal 1-d’. This method requires that the primary occupation and income of the landowner be based on agricultural production. The land must be devoted to agriculture as the value of the land, and subsequent tax assessment, is based on the revenue associated with the property and its ability to produce agricultural products. Market value is not a consideration. An agricultural exemption must be applied for annually, whereas an open-space exemption remains in place until the use or category changes.

PENALTIES AND ROLLBACK TAXES….BEWARE
In either case, a landowner should contact their local county appraisal office for the specific regulations and requirements within their county (and state). A landowner should also be aware of the penalties associated with incorrect reporting and “rollback taxes”. Rollback taxes are applied when a change of use occurs on property previously under either ag related type exemption and include the past 3-5+ years of taxes at present market value. Rollback taxes can be quite substantial (and punitive at times), so if it important to be knowledgeable if you are considering purchasing property or a change of use.

While tax codes are rarely simple or straightforward, when it comes to “ag exemptions” it definitely pays to do your research and Miniature Herefords may just be the answer you are looking for!

Mini Herefords: Good for Health

Ranching and Neuroscience: going hand in hand.

Well, I was going to write an in depth piece on the way manual labor enhances our well being and helps to insulate the brain from depression, backed up by some pretty interesting new research, but decided to keep this one on the relative light side.
We all have our miniature Herefords for a variety of reasons; the investment and return value is but a small factor. There certainly has to be more involved than the wallet to be really successful in any endeavor, be it cattle or baking cakes; there has to be the passion. And reward. Those who succeed do so because they believe in what they are doing is good for something or someone. They have a passion and can see real, tangible results from their efforts…these are the successful people we see in all walks of life, raising really good (anything)… miniature Herefords being just one example.
Working with ones hands gives immediate results and therefore gratification. These results, whether building a fence or helping a newborn calf to its feet, engage a part of the brain that is responsible for a sense of well being and gratification, taking our minds off the bigger issues in our lives that maybe mentally weighing us down. This may explain why so many folks with high powered – high stress occupations such as doctors, lawyers and others find farming and ranching as a way to relax and detox from their everyday lives. New research indicates for the first time that the simplicity and repetition (think sewing, ranching, gardening, etc!) of working with the hands, engaging the problem solving area of the brain, and seeing real, tangible results is the feel- good reward we all crave and, apparently need to protect against depression.
There is no place I would rather be than out working with my cattle. Building fence or hanging a gate, feeding and watching the animals eat, working with the vet. For many years I (and my family especially) thought there must be something seriously wrong with me. But now I finally understand the draw and desire that raising cattle has for me personally; immediate and tangible rewards from my mental and physical time invested. Is there anything more relaxing than leaning on a gate watching your animals as they move through a new pasture or kick up their heels in sheer delight for the life you have had a hand in providing?
For me, not much. Aside from watching my own children as they mature towards responsible adulthood, my cattle keep me sane. What more can I say. Crazy? If not for my small farm and my small herd of small cattle, I probably, quite seriously, would be.
So go ahead, take some time to enjoy the fruits of your labors. Go “kill some time” “puttering” (do we dare even do that these days?) around your place and with your animals. It may very well be the best therapy there is. .

Cattle Parasites Prevalent, Not always Controlled

Source: CattleNetwork.com

New data from the USDA’s National Animal Health Monitoring System (NAHMS) show widespread prevalence of internal parasites in cow-calf operations, and suggest control measures fall short on many operations. Bert Stromberg, PhD, a professor of veterinary pathobiology and associate dean at the University of Minnesota presented the NAHMS results today to the Academy of Veterinary Consultants in Denver.

Parasite control is one of the most costeffective investments a rancher can make. Research from Iowa State University, for example, shows that eliminating dewormers
in a cow-calf operation impacts breakeven prices by 34 percent, at an added cost of $165 per head, due primarily to lower weaning rates and weaning weights. The news
NAHMS study shows, however, that many producers are missing some of the benefits of a good parasite-control program. The NAHMS researchers surveyed producers from 24 states representing 88 percent of U.S. beef cows regarding their parasitecontrol practices, and asked them to voluntarily collect fecal samples from their herds.

The study shows that for operations with unweaned calves or weaned stocker calves, over half dewormed these animals at least once per year. About 70 percent deworm
replacement heifers once or more per year and just over 80 percent deworm cows at least once per year. Of those who deworm their cattle, 85 percent use a regular schedule to determine when the treatments take place.

In this study, only 5.7 percent of producers had performed fecal testing to evaluate parasite burdens during the past three years. For Phase 1 of the study, participants
send fecal samples from 20 randomly selected weaned beef calves six to 18 months of age, that were on pasture for at least four weeks and had not been dewormed
for at least 45 days. Laboratory testing of samples from 99 operations showed 85.6 percent positive for strongyle-type eggs, 18 percent positive for nematatodirus, and
60 percent positive for coccidia oocytes. For Phase 2, the researchers asked participants to deworm their calves with whatever product they typically use, according to label directions, then submit a second set of fecal samples. Laboratories connducted “fecal egg count reduction” (FECR) tests to determine the efficacy of the deworming treatments.

Among participating operations, Stromberg says, 31 percent achieved efficacy rates below 80 percent for strongyle-type egg counts, and 44 percent had efficacy rates below 90 percent. Results below 90 percent efficacy, he adds, indicate the presence of anthelmintic resistance among parasite populations. For nomatatodirus, 62 percent of the operations had less then 90 percent reduction and 57 percent had less than 80 percent efficacy.

Stromberg says improper or incomplete treatment probably accounts for some lack of treatment success, such as when producers miss some cattle or misjudge their weights and apply the wrong dose. The data also suggest, however, that worm populations are developing resistance to some dewormers, resulting in a decline in efficacy.
The researchers acknowledge that more study will be needed to determine the extent of resistance to anthelmintics among parasite populations and to develop recommendations for ensuring the continued effectiveness of these products. In the meantime, Stromberg reminds producers to work with their veterinarians to develop
strategic deworming programs to treat parasites in their animals and reduce shedding of parasite eggs that contaminate pastures.

Nitrate Poisoning

Source: Texas & Southwestern Cattle Raisers Association

Watch out for nitrate poisoning in forages and forbes.

This year’s Fall weather– rain and clouds following a drought – and its effect on forages can be a recipe for nitrate poisoning of livestock, said a Texas AgriLife Extension Service expert. Under these conditions, cattle don’t have to consume improved forages to be at risk, as many weeds also can build up high levels of nitrate, said Dr. Vanessa Corriher, AgriLife Extension forage specialist.

“In a recent incident, a Sabine County producer turned some cattle into a dry lot,” she said. “Though he supplied hay, the cattle apparently died of nitrate poisoning from eating pigweed in the lot.”

Corriher noted that livestock generally won’t consume weeds when they have quality hay available, but in this instance they did and several cattle died as a result. Forages and small grains that are susceptible to building up high levels of nitrate include sudangrass, sorghum-sudan hybrids, pearl millet, corn, wheat and oats. Weeds prone to build up high nitrate levels include Canada thistle, pigweed, smartweed, ragweed, lambsquarter, goldenrod, nightshades, bindweed, Russian thistle and stinging nettle.

Another risk factor is hay cut during or just after a drought period.

“This is especially risky if nitrogen was applied just prior to the hay harvest,” Corriher said.

Though the high nitrate levels are associated with weather conditions, once the levels are built up in hay, the risk is not lessened over time.

Nitrates are present in all forages, Corriher said. Strictly speaking, the nitrate poisoning should be called “nitrite” poisoning. With normal levels of nitrates, the range animal’s rumen converts the nitrate (NO3) into nitrite (NO2), which in turn is converted to ammonia, then into amino acids and then into proteins.
But when nitrate levels are high in forages, the process becomes subverted, and high levels of nitrites are absorbed directly into the bloodstream through the rumen wall. The nitrite converts the hemoglobin in the blood into a form that cannot transport oxygen. The blood turns from a bright red to a chocolate color, and the animal essentially dies of asphyxiation.

Corriher recommended producers regularly take forage samples from pastures and have them analyzed for nitrates, including samples of forages and weeds at various growth stages.
“Be sure to specify that you want nitrate analysis,” she said. “Standard nutritional analysis usually does not test for nitrates.”

Hay samples should be collected with a probe. Samples from several bales can be combined. Unlike prussic acid poisoning, the risk of nitrate poisoning is not decreased over time. Hay harvested months ago could still contain the same high levels of nitrates it did when baled.

“Though the risk of nitrate poisoning is higher after a drought or an extended period of cool, wet weather, it’s something producers should be aware of year round,” Corriher explained.

An Ounce of Prevention May Lead to More Pounds of Live Calves from Heifers

Source: The Samuel Roberts Noble Foundation www.noble.org, Written by Billy Cook

With the current price of replacement cattle, we must maximize the number of heifers that become productive cows. I am making the big assumption that at this stage in the game everything has gone right (the heifers weighed at least 65 percent of mature weight at breeding, they were bred to proven low-birth-weight bulls, they were culled
on poor structure and small pelvic area, they were provided with adequate nutrition up to this point, etc.). But your job as a manager and caretaker of these heifers is still far from done. Heifer performance from this point forward will be determined by how well the heifer is managed up to and after the time she has her first calf.

These spring-calving bred heifers grazing native pasture have done well through the summer, but they need a good supplement plan be prepared to calve in February.
A common statement we livestock specialists hear this time of year is, “I don’t want to over-supplement these heifers or their calves will be too big, and I will have increased calving difficulty.”

A University of Wyoming study (L. R. Corah, et al., Univ. of Wyoming. 1975. J. Anim. Sci. 41:819) illustrated the effects of level of nutrition on the calving performance of first-calf heifers. Heifers were divided into two groups 100 days prior to calving. One group received a ration meeting National Research Council (NRC) requirements for energy (TDN), and the other group received 65 percent of NRC requirements for TDN. Both rations were formulated to meet protein requirements. After calving, both groups received TDN and protein that met the NRC requirements. In the low-level TDN group, birth weights were reduced by about 5 pounds, but there was no reduction
in calving difficulty (Table 1). Calf losses at birth were higher in the low TDN group. Weaning weight was 28 pounds heavier for the calves out of the heifers fed the higher energy ration. The take-home message here in terms of calf production is obvious: There are more live calves with higher weaning weights produced from the heifers fed the higher TDN ration. This in itself should make the decision to supplement your heifers at an adequate energy rate an easy one to make.

However, in addition to the increase in calf production, when the researchers examined the return to estrus after calving, those firstcalf heifers receiving adequate energy prior to calving also came into heat sooner, allowing them the opportunity to breed earlier in the calving season. Evan Whitley, in his April 2001 NF Ag News and Views article Spring Clean Your Breeding Program, illustrated the importance of heifers and cows calving early in the breeding season.

To further illustrate the importance of nutritional status of the bred two-year-old heifer in the last trimester of pregnancy, consider that the heifer must continue to grow and gain body weight during this 90-day period. The weight of the fetus, fetal fluids, membranes, etc., will increase almost one pound per day. Therefore, to sustain her
growth and the growth of the fetus she is carrying, the heifer needs to gain about 1 to 1.5 lbs. per day. The typical heifer will lose 100 to 125 lbs. when she calves (weight of the calf, fetal membranes and fluids). This weight represents about 10 to 14 percent of her body weight; therefore, she must be prepared nutritionally to handle this stress. She also must be managed differently and separately from the mature cow herd. Heifers that calve late typically breed back late. To ensure them a chance to rebreed in a timely manner and remain in your herd, separate them and feed them additional supplement as compared to your mature cow herd, or provide them with the highest-quality pasture you have available.

MHBA ANIMAL HEALTH SERIES: Bovine Viral Diarrhea Virus-BVDV

It is that time of year again and as many of us prepare to make the trek to Denver for the National Miniature Hereford Show, some may wonder about the importance of BVD-PI testing for all show and sale animals. The following information is intended to provide a simplified overview of the disease, transmission and herd eradication. For specific information related to your animals’ exposure contact your ranch veterinarian.
What is BVDV?
Bovine Viral Diarrhea Virus (BVDV) is a virus known to infect domestic livestock and some wild animals. For cattle producers the virus causes economic losses through decreased weight gains, decreased milk production, reproductive losses (abortions), and animal death. There are two categories of BVD infections.
1- Transient (acute) infection (“TI”)
• Short term (weeks)
• Acquired after birth
• TI cattle become immune and clear virus
• Greater than 95% of BVD infections are TI
• TI cattle are a minor source of virus spread in herd
2- Persistent (chronic) infection (“PI”)
• Life long persistent infection acquired while in the uterus therefore only fetal infections results in BVD-PI
• PI cattle can never become immune
•Less than 5% of BVD infection are PI
• PI cattle in herds are the major source of virus spread
Over 90% of BVD-PI calves are born from normal dams (no prior BVDV exposure)

Development of BVD PI

Persistently infected (PI) BVD cattle are created when the dam and her fetus become infected with BVD virus between 45 to 125 days after conception. During this period of development, the immune system of the fetus has not yet developed and the BVD infection is not recognized. The fetus is not capable of recognizing the virus and does not develop antibodies against the BVD. Fetuses infected during this period survive and are permanently infected with the BVD virus, shedding the virus throughout their lifetime.

Signs and symptoms of BVD-PI

Most BVDV infection problems in cattle herds go unnoticed since 70-90% of BVD infections do not result in observable signs of disease. When present, the most common disease caused by BVD virus infection in cattle herds is poor reproductive performance including, abortions, poor conception rates, stillbirths, and weak calves. The BVD virus infection can causes suppression of the bovine immune system resulting in increased susceptibility to other infectious diseases such as scours, pneumonia and poor weaning weights.

How is BVDV transmitted?

The main source of BVDV in cattle herds is BVDPI animals. Virus in BVD-PI animals is shed in all body secretions including nasal discharge, saliva, tears, milk, feces, urine and semen. Transmission occurs via ingestion, inhalation, and even such things as boots and vehicles. The most common ways that BVDV can enter a herd are as follows:
• By purchasing replacement cattle at auctions
• By purchasing a pregnant animal with PI calf
• Introducing replacements or show stock without quarantine
• Failure to maintain a BVD vaccination program
• Failure to test replacements for BVD PI
• Contaminated semen or embryos
• Borrowed or unknown bulls

Why test and remove BVD-PI animals from a cattle herd?

Persistently infected (PI) cattle are the major source of BVD infection and disease in cattle because they shed huge amount of BVD virus throughout their lives. The major economic loss associated with BVD in cattle operations is loss of income due to loss of calves either before birth (abortion), at birth (weak calves) or between birth and weaning, or from diseases associated with immunosuppression such as scours and pneumonia.

Can BVDV infection be eradicated from a herd with vaccination?

No, BVD vaccination alone (with either modified-live or killed vaccines) cannot keep a cattle herd free of BVD-PI cattle nor completely control BVD infection according to the Academy of Veterinary Consultants and American Association of Bovine Practitioners. Both groups promote a threepronged approach to BVD control, a combination
of BVD-PI testing and removal, vaccination and biosecurity, (good herdsmanship, sanitation, record keeping, and an active MLV vaccination program).

Ethics-Do the right thing!

Do not knowingly share your BVDV problem with unsuspecting buyers. BVD-PI is a serious problem that if kept unchecked could create devastating losses for a breeder. It is unethical to pass animals with known or suspected BVDV infections on to another breeder.

Inve$ting in Minis

By Diane Alu

Ok, I confess, there is more to my owning registered miniature Herefords than meets the eye. Yeah, they’re the cute, fuzzy half-size renditions of the full size beef machine, and make excellent pasture mowers, conversation pieces, moveable lawn ornaments, ag tax exemption enablers. Wonderful for the grandkids, 4H, local fairs and national
shows. Stress relief, therapy, bragging rites and grass fed beef for my family…..but, I confess, aside from all the above reasons and probably a few I omitted, the tipping point for my investing in the registered miniature Hereford was just that….investment.

When trying to decide what to stock our small farm with, I wanted something that, quite frankly, would give me a good return on my initial investment. Many factors needed to be considered when one has a certain amount of cash to invest, and what kind of return one desires. But I think the most important factor, in my eyes, was the ability to control the desired outcome that livestock provides.

You get out what you put in. Meaning, start with quality stock, breed for quality stock, take care of your investment, and you can pretty much design your own “portfolio” and returns as you wish.

I grew up with the old time notion that there were no pets on a working farm (or very few), everyone had to pay their way. If an animal did not earn its keep, it didn’t stay.
With 10 or 12 acres to get the maximum return on, I had to choose an animal that I thought there would be demand for, not only for beef, but for registered breeding stock as well. It had to be docile, easy to handle, easy to fence, care for, feed and house. I wanted an animal with a pedigree, a history, a connection with our country. It had to be hardy, fertile, and efficient. And, most importantly, it had to produce a product that would be sought after. If not for breeding, it could produce excellent beef. And people always need food. How many animals fit that bill? In fact, almost every animal I sell and breed is sold for breeding stock to someone that desires to start a herd of their own, or add to an existing one. Those that don’t will become healthy, safe, grass fed beef. And with all the bad press and recalls the beef industry is getting these days, it is no surprise that people are looking for locally produced food for their families.

The registered miniature Hereford, as I have said before, is a safe place for my money. Why would I send my hard earned cash to some broker and wonder where my money went and what kind of return I will get, if any? I see my investment in my front pasture, I work it as much or as little as I want or need to, and, with the animals being half the size of conventional beef animals, I am able to get double the stocking rate per acre and therefore twice the yearly return per acre with a calf, that, if done correctly, will be worth at least as much or more than what I paid for its dam. And the Hereford will do it typically at 2 years of age, and every year thereafter with minimal input.

You may call that calf cute, pet, show stock or dinner; I call it my little dividend. Two years later that one calf will be having her own calf, and its dam will have had another calf as well. You get the idea.I’m sure you can think of at least one well known, famous, or wealthy person who owns a ranch or farm and livestock. Think about why they do. If you’re still not sure, pick up a Newsweek or Time magazine, New York Times or Wall Street Journal. Smart investors are informed and involved in their investments.

Isn’t it time you took control of your finances and investments? Consider the registered miniature Hereford today. You will not be disappointed.
