Animal science is one of the largest majors on campus and the largest within the College of Agricultural and Natural Resources. Animal science is the science and business of domestic animals, including companion animals and livestock species (horses, beef and dairy cattle, sheep, goats, swine and poultry). Within our animal science major, a student can study health, production, merchandising, biotechnology, education, operations, communications, or business.

Our department offers an excellent pre-vet option and directs the pre-professional course preparation for veterinary medicine. We also have degree plans available for students interested in pre-professional health, nursing, and law.

Our department has prominent judging teams. Together, they have earned more national championships than any other university in the country.  We also have fully-functioning farms and hands-on teaching facilities encompassing 13,000 acres, which many other universities cannot provide.
