 Livestock Herd Health and Reproduction Service

Welcome to the Livestock Herd Health and Reproduction Service at the UC Davis Veterinary Medical Teaching Hospital, where we treat dairy cattle, beef cattle, sheep, goats and swine.

The Livestock Herd Health and Reproduction Service is multi-faceted, providing both in-house and ambulatory services to dairies, ranches and breeding operations within the greater Davis area. A team of specialists and residents is available for appointments and consultations in a variety of areas.

The health of each individual animal is extremely important, as is the collective health of all animals in the herd. Healthy individuals lead to a healthy herd, and vice versa. The Livestock Herd Health and Reproduction Service can work with you on all aspects of preventative medicine including vaccination and parasite control, mineral and nutrition analysis, records analysis and regulatory services. In the unfortunate event that you are dealing with disease in your herd, this service can help to re-establish disease monitoring parameters, treatment protocols and eventually a healthy population.

An essential component of any commercial livestock operation or hobby farm is a solid basis in reproduction. Males and females both contribute to a successful program, but both can also experience infertility for a variety of reasons. The Livestock Herd Health and Reproduction Service can work with you to diagnose pregnancy in females, perform breeding soundness exams on males, test for venereal diseases, and diagnose infertility and abortions. With a reproductively healthy herd, more advanced reproductive procedures may be explored to improve genetics and production.
