Studying the biology and management of dairy cows can lead to improvements in dairy production, animal welfare, human nutrition, and environmental protections. Students in the dairy science major learn all of these principles while embracing innovation and technology to meet needs in the dairy industry. The Department of Animal and Dairy Sciences, home of the undergraduate program in dairy science, produces skilled leaders who address the challenges of animal health and welfare, land and water stewardship, precision livestock farming, food safety, and biomedical advancements.

A 10:1 student-faculty ratio and small classes allow for meaningful connections. Out-of-classroom learning opportunities, such as internships on farms or with agribusiness, give students the training they need for successful 21st-century careers. Students can also gain valuable experience in research labs or in the student-operated Dairy Cattle Center.

Students majoring in dairy science are working toward a variety of careers that require a strong background in animal biology including agribusiness, dairy farm management, technical services and consulting, research, and teaching. Students also prepare for veterinary medicine or graduate school.

Learn through hands-on, real-world experiences

 UW–Madison has cows on campus. The Dairy Cattle Center is located near classrooms giving students access to cows during lab sessions. But dairy science isn’t just about milking cows—it includes genetics, nutrition, lactation, and biological and digital technologies that are relevant to the dairy industry and beyond. Out-of-the-classroom experiences are the norm for dairy science students, with 100 percent of students completing an internship or field experience.

Field courses include dairy nutrition and dairy cattle judging. Lab courses cover dairy herd management, lactation, reproduction, and dairy cattle improvement. Students solve problems through field trips to working commercial dairy operations.

Build community and networks

Madison is an ideal location for the study of dairy science. It is a vibrant city—home to many large agribusinesses—that’s also located close to dairy farms. Students volunteer in a variety of activities directed by the Badger Dairy Club. The largest effort is their work at the World Dairy Expo, an international dairy event held in Madison.

Customize a path of study

Dairy science students can customize their coursework to fit their career goals with a large variety of classes in the department. The major can be combined with other majors such as agricultural business management, genetics and genomics, life science communications, or agronomy. Students can also pursue Honors in Dairy Science.

Make a strong start

Students can take an introductory seminar course that helps them develop an individualized four-year course plan, learn about internships and job opportunities, and discuss leadership development opportunities.

Gain global perspective

Dairy science majors are encouraged to go on study abroad programs, where they can immerse themselves in research or field experiences. In recent years, a program to central Mexico has focused on global agricultural, rural development, and the relationship between the U.S. and Mexican dairy industries, and many students have completed a semester abroad in The Netherlands. Students can explore studying abroad as a Dairy Science major by utilizing the Dairy Science 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.

 In the dairy science program, 100 percent of students complete an internship or field experience. The department offers an internship course under the guidance of a faculty or staff member.

 UW–Madison’s proximity to farms, agribusinesses, and events—such as World Dairy Expo—provide undergraduates with unique networking experiences and valuable hands-on learning. 

Research experience

More than half of the students complete a research project under mentorship from a faculty member. Dairy science researchers are internationally recognized specialists in nutrition, genetics, lactation, reproduction, animal welfare, herd management, and more. Students can take on research projects with faculty members for either course credit or pay, depending on the opportunity.

Student organizations

 The Badger Dairy Club is a large, motivated student organization on campus with more than 75 members of various majors who share a passion for the dairy industry. Students are involved in dairy industry events that provide leadership and networking opportunities. Highlights of the club’s activities include work at the World Dairy Expo, hosting the Badger Invitational Sale, volunteering at the Wisconsin 4-H Dairy Bowl and FFA Dairy Judging Contests, and club trips.

There are other opportunities for students to get involved in agriculture-related organizations on campus such as Collegiate FFA, Association of Women in Agriculture, Babcock House, and Alpha Gamma Rho.

Competitive teams

 Students can join competitive teams that take part in Intercollegiate Dairy Judging, the North American Intercollegiate Dairy Challenge, and the Animal Welfare Assessment Contest.

Global engagement

 Dairy science students are encouraged to study abroad; the department offers globally focused courses that look at livestock production, health, animal agriculture, and sustainable development, including a summer field study program focused on animal agriculture. Students can find more information on the International Academic Programs website and the CALS study abroad advising page.

In addition to study abroad programs, the dairy science major offers several courses that cover animal systems and their improvement in developing countries, the world role of U.S. animal agriculture, and food production related to human and environmental health, land use, and social justice.

Community engagement and volunteering

 Students volunteer at a number of activities directed by the Badger Dairy Club. The largest effort is their work at the World Dairy Expo, an international dairy event held in Madison. There students have the unique opportunity to be directly involved in the event working behind the scenes before, during, and after the show.

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


 The department offers more than 30 scholarships and awards more than $170,000 annually.

 Students across the College of Agricultural and Life Sciences receive more than $1.25 million in scholarships annually. Learn more about college scholarships here.

 UW–Madison has specialized facilities offering students hands-on dairy science experiences, including:

  • The Dairy Cattle Center is home to more than 80 dairy cows on campus in a tie-stall barn.
  • A network of off-campus Agricultural Research Stations serve as living laboratories for dairy research to enhance research taking place on campus.
  • The Babcock Dairy Plant is a fully operational dairy plant with a retail store selling dairy products. Students can find part-time work and experience in a wide range of dairy processing jobs.
