Animal Science major

Why major in animal science?

Be part of solving one of humanity’s most critical grand challenges – the global demand for food and fiber. With the population expected to grow by 2.3 billion by 2050, feeding the world will require raising overall food production by 70 percent. You will become knowledgeable in animal nutrition, health, behavior, reproduction, physiology, genetics and animal management. You will play an important role in education and the conservation of non-domesticated animals housed in zoos, aquariums and sanctuaries. You will also contribute to a greater understanding of the complex relationships between domestic animals (livestock and pets), wild animals, humans and our shared environment.


In your first semester, you will work with horses, cows, sheep and yes, blue hens, on our 350-acre farm. Step out of our back door and into the horse barn where you will learn to assess equine gaits. In the classroom, study lactational physiology and milk the cows in the dairy cattle milking parlor. From the farm, our milk is processed and returned to our own UDairy Creamery, where you will experience both the science and business of making ice cream. You can even raise and train a service dog in your residence hall! Through our study abroad program in New Zealand, gain a truly global perspective of the world food import and export economy. Develop a greater understanding of the importance of sustainable animal production. Our combination of courses in the basic sciences and hands-on experience with animals makes our program truly distinctive.

Course highlights

Instructors introduce how domestic food animals function, genetics, nutrition, reproductive physiology, behavior and animal health. The course begins with a dialogue about the human-animal bond and the role of animals in society, and ends with the discussion of how agricultural animals are managed to produce safe and healthy food.

Instructors introduce the concept of One Health — the integration of human, animal and environmental health. The ultimate goal of One Health is prevention and early intervention, moving upstream of a health problem. Class discussion covers worldwide animal production practices, habitat destruction and other human activities, environmental changes, and the incidence of zoonotic outbreaks. Students focus on bacterial, viral and fungal zoonotic and emerging diseases like COVID-19, agriculture and the use and misuse of antibiotics in animal and human health.

Instructors cover the relationship between form and function in domestic farm animals. Students conduct comparative examination of body systems in order to better understand the various management practices employed in animal agriculture.

Modern technologies heighten the inexorable links between the animals and their environments, making environmental management more important. Instructors discuss the principles of animal environment management related to companion, farm and research animals. Course laboratories reinforce development of hands-on skills.

Instructors teach the fundamentals of physiology and lactation involved in initiation, maintenance and cessation of lactation, neuroendocrine control of lactation, nutrient absorption and processing by mammary gland and control of milk composition. Topics include mammals of commercial dairy importance as well as rodents, horses and humans.
