Generally, the Miniature Hereford cow is a very capable mother and can raise her calf without much interference. The calf should be properly identified and marked early on, and watched closely as he grows. Vaccinations should be administered as recommended by a trusted veterinarian, keeping your local requirements in mind. Calves are weaned from 4-6 months of age, depending on breeding practices and the theories of the individual breeder. Weaning can be a stressful time, so use it to treat the calf well with good hay, mineral, and extra supplementation as he learns to survive without milk.
