Content last reviewed: August 2026

Animal science studies the biology, nutrition, breeding, and management of livestock and other animals, combining biological science with hands-on animal care and agricultural production knowledge. Many programs let students focus on a species area (dairy, poultry, equine) or a functional area (nutrition, reproduction).

Hands-on work with live animals is central, on university farms, at partner operations, or through internships, giving direct experience with animal handling and husbandry alongside the biology coursework.

Typical courses you might take

  • Animal Biology & Physiology
  • Animal Nutrition
  • Animal Breeding & Genetics
  • Animal Reproduction
  • Livestock Management
  • Animal Health & Disease
  • Feeds & Feeding
  • Applied Animal Science Practicum
