Animal science is the study of domestic animals including livestock species (horses, beef and dairy cattle, sheep, goats, swine and poultry) and companion animals. Students study concepts from production through processing and learn about the value associated with livestock, as well as meat and milk produced from those animals.Animal scientists apply the principles of biological and social sciences to animal nutrition, genetics, reproduction, behavior and health. Livestock production systems, animal management and husbandry, animal products, and much more are part of the study of animal science.
