Admission to Degree Program

All degree programs in the Department of Animal Science are open enrollment.

The Discipline

Agribusiness-Production provides both breadth and depth in science and business for farm and ranch management and related agribusiness vocations, e.g., sales, banking institutions, state and federal government agencies, etc.

Veterinary Technology combines science and technology to prepare students for careers at veterinary clinics, research laboratories, etc.

Science-Preveterinary Medicine and Molecular Biology are the emphases for students needing a strong science background as they prepare for professional schools and advanced degrees.

Career Opportunities

The various curricula in the Department of Animal Science offer specialization and employment opportunities for the following: (1) livestock management and production; (2) meat, dairy, and food processing; (3) sales consulting and representing agricultural businesses; (4) animal health technology, assisting the veterinary practice and related fields; (5) advanced study to graduate and veterinary schools; and (6) working with federal and state agencies (extension, meat grading and inspection, etc.).
