Studying the biology of domesticated animals helps us better understand their health. The major addresses important issues related to animal health and welfare, biomedical advancements, food safety, precision livestock farming, and land and water stewardship.

Students in the Animal and Veterinary Biosciences major learn about cattle, swine, sheep, horses, poultry, and goats, as well as companion animals such as cats and dogs. They also examine recent discoveries connecting human and animal health.

The Department of Animal and Dairy Sciences is home to the undergraduate program in Animal and Veterinary Biosciences. The department produces skilled leaders in animal agriculture and sustainable food systems while embracing innovation and technology. A 10:1 student-faculty ratio and small classes allow for meaningful connections among students and instructors.

Students can take courses on an assortment of topics including animal breeding, veterinary genetics, animal health and welfare, physiology, and animal nutrition utilizing various animals as a vehicle for learning. The major offers a science-focused path for students interested in veterinary medicine, animal science, bioscience, or other graduate programs.

Learn through hands-on, real world experiences

The program emphasizes hands-on learning, and students choose from more than a dozen lab courses covering animal handling, reproductive biology, veterinary genetics, animal welfare, meat science and biologics, and more. Field courses look at international agriculture and sustainability. The department encourages Animal and Veterinary Biosciences majors to get involved with internships and research with faculty and staff.

Build community and networks

Animal and Veterinary Biosciences majors find a welcoming community where professors know their students and can provide guidance based on their specific goals. Outside of the classroom, students can join several student organizations including the Pre-Veterinary Association, Saddle and Sirloin Club, Poultry Club, Badger Dairy Club, and Badger Meat Science Club.

Customize a path of study

Students can choose from a variety of breadth and depth courses to explore their interests within the major, customizing their coursework to fit their career goals. Course flexibility allows students to complete several pre-veterinary requirements, a certificate, or double major within the curriculum. Students can elect to complete Honors in Animal and Veterinary Biosciences.

Make a strong start

The department offers an introductory seminar course that helps students maximize their education, develop professional skills, and make informed decisions about their classes, internships, and career path. Multiple Animal Sciences courses are open to first-year students offering additional opportunities to establish connections to the major.

Gain global perspective

Students are encouraged to study abroad; the department offers globally focused courses that look at livestock production, health, animal agriculture, and sustainable development. Students can explore studying abroad as an Animal and Veterinary Biosciences major utilizing the Animal and Veterinary Biosciences Major Advising Page. Students work with their advisor and the CALS study abroad office to identify appropriate programs.

To declare this major, students must be admitted to UW–Madison and the College of Agricultural and Life Sciences (CALS). For information about becoming a CALS first-year or transfer student, see Entering the College.

Students who attend Student Orientation, Advising, and Registration (SOAR) with the College of Agricultural and Life Sciences have the option to declare this major at SOAR.  Students may otherwise declare after they have begun their undergraduate studies. For more information, contact the advisor listed in the Contact Box for the major.

Each student receives one-on-one guidance from their professional advisor. Academic advisors will help students build an individualized, four-year plan. Many Animal and Veterinary Biosciences majors complete certificates or double majors. Customary examples include Life Sciences Communication, Genetics and Genomics, Global Health, CALS Business Management, and opportunities outside of CALS such as foreign languages, depending on the students’ interests.

Career Opportunities

All students have a faculty mentor to assist with their career planning.

Students graduating with a degree in Animal and Veterinary Biosciences can enter a number of career fields. These include nutrition and genetics, health and welfare, animal management and monitoring technology, meat science and biologics, food and animal research, and teaching.  Many students go on to pursue professional education in veterinary medicine, graduate programs in animal science, or human medicine.

Animal and Veterinary Biosciences majors take part in a number of internships around campus and beyond. Past students interned at veterinary clinics and hospitals, genetics companies, animal feed companies, Extension, food companies, farms, animal pharmaceutical companies, animal councils, humane societies, and more.

On campus opportunities at department animal care facilities, UW veterinary school, and at Bucky’s Varsity Meats, give students hands-on experience each semester.

Research experience

There are numerous opportunities to conduct research with faculty and staff in the department. Around 75 percent of Animal and Veterinary Biosciences majors have completed independent study projects. Several research stipends are available and some students also take part in research as part of an honors thesis.

Student organizations

By joining a student organization, Animal and Veterinary Biosciences majors connect with other students and build relationships with faculty and staff. Organizations of particular interest to Animal and Veterinary Biosciences students include Pre Vet Association, Saddle and Sirloin Club, Poultry Club, Badger Dairy Club, and Badger Meat Science Club.

There are additional opportunities for students to get involved in animal or agriculture related organizations on campus such as Hoofer Riding Club, Association of Women in Agriculture, Babcock House, and Collegiate FFA.

Global engagement

The department encourages students to study abroad and offers globally focused courses that look at animal health, animal agriculture, and sustainable development. Students can find more information on the International Academic Programs website and the CALS study abroad advising page.

Community engagement and volunteering

Animal and Veterinary Biosciences students engage in a number of volunteer opportunities including working at the Livestock Lab, the Poultry Research Lab, the Dairy Cattle Center, Bucky’s Varsity Meats, and Animal Farm Units. Students also participate in undergraduate student recruitment events, 4-H and Extension events, Dane County Humane Society, and spay/neuter clinics.

On campus, the Morgridge Center for Public Service provides resources to help students connect with volunteer opportunities based on their interests and goals.

The Animal and Veterinary Biosciences program awards $25,000 – 35,000 in annual scholarships. Students in the College of Agricultural and Life Sciences receive more than $1.25 million in scholarships annually. Learn more about college scholarships here.

Campus facilities offering students hands-on experiences:
