Animal Science: courses, careers, and where to study

Animal Science studies the breeding, nutrition, and husbandry of agricultural animals and the production and processing of animal products.

Animal Science focuses on the scientific principles behind raising agricultural animals and turning their output into food and other products. Students study how cattle, swine, poultry, sheep, and other livestock grow, reproduce, and respond to feed, and they learn the genetics and breeding decisions that shape herds and flocks over generations. Coursework joins core biology and chemistry with applied subjects such as animal nutrition, physiology, reproduction, meat and dairy science, and the husbandry practices that keep animals healthy and productive. This agricultural focus is what sets the field apart from its neighbors. Biology examines living systems broadly, Zoology centers on wild and non-domesticated animals, and Veterinary Technology trains people for clinical care under a veterinarian, while Animal Science keeps its attention on the production, processing, and distribution of agricultural animal products.

Most students enter through a bachelor's program, which is the typical preparation for working as an animal scientist, and the degree blends classroom science with hands-on learning. Expect laboratory work in nutrition and genetics, time at university farms or teaching herds, and practicums or internships on commercial operations, in feed and breeding companies, or in food-processing settings. Graduates work in livestock and dairy production, animal nutrition and feed manufacturing, breeding and genetics firms, extension and agribusiness, and food-quality roles, and many use the major as a pre-veterinary path toward graduate or professional study. If you are aiming at veterinary school, a specific certification, or a regulated production role, verify the exact prerequisites, course sequence, and any credential expectations directly with the program and your state before you enroll.

In federal data for the closely related occupation of animal scientists, the U.S. Bureau of Labor Statistics reports a 2024 median wage of $79,120 and projects employment to grow about 5.8% from 2024 to 2034; a bachelor's degree is the typical entry-level education for that occupation. National figures are occupation-wide medians across all experience levels, not starting wages or graduate outcomes.
