About the Department

The Department of Animal Science at Penn State has one of the oldest and best programs in the country.

Penn State Animal Science is a national leader for animal science teaching, research, and extension programs. Our small-school atmosphere facilitates a warm, welcoming, intellectually stimulating, and professional environment.

We’re industry focused and connected. We boast state-of-the-art facilities and world-class faculty with years of working experience in their fields. The best faculty in their respective disciplines are recruited from around the globe to push students to excel and move the needle on critical research. Our facilities are best in class and uniquely close to the heart of the Penn State experience. Barns, research plots, and laboratories are just steps away, including the new Animal, Veterinary, and Biomedical Sciences Building.

Student success drives the department. Our undergraduate programs offer students hands-on science with real-world applications, excellent internship experiences, robust scholarship opportunities, and high job placement.

Our graduate programs offer master of science and doctoral degrees. Graduate students receive in-depth training in core science and management disciplines, conduct groundbreaking research, and teach classes.

Student success and cutting-edge, well-funded research are the lead departmental drivers. Students are encouraged to participate in meaningful research from the first semester of their freshman year.

Current Animal Science research areas include animal products and human health, dairy, deer, equine, livestock, meat science and muscle biology, nutrient management and environmental stewardship, poultry, quality and safety of animal foods, and reproductive biology and fertility.
