Environment & Sustainability

Animal Science major, explained.

Study animal biology, health, nutrition, behavior, and human care.

Animal Science explores how anatomy, physiology, nutrition, genetics, behavior, welfare, reproduction, and management shape domestic and agricultural animals. Students commonly study Animal physiology, Nutrition, Genetics and breeding, Animal behavior and welfare, and Health and management. Programs vary by college, but the field generally combines foundational ideas with applied work so students can investigate meaningful questions, make informed decisions, and communicate what they discover.

What can you do with this major?

One major. More than one direction.

These are example connections, not guaranteed outcomes. Many careers welcome more than one major, and some require additional education or licensure.

Animal Care Program Coordinator

Supports health, welfare, records, staff practices, and daily animal-care operations.

Animal Nutrition Associate

Helps evaluate feed ingredients, nutritional needs, product information, and feeding programs.

Livestock Production Specialist

Supports animal health, reproduction, welfare, facilities, and production management.

Veterinary Research Assistant

Supports studies of animal health, disease, behavior, treatment, or biological systems.

Veterinary medicine requires a professional veterinary degree and licensure. Animal science can provide relevant preparation, but students must complete specific veterinary-school prerequisites.
