Knowra Animal science Animal science Animal science studies the biology, care, breeding, and management of domesticated animals, especially livestock raised for food, fiber, work, or companionship.
Animal physiology : The study of how animals’ bodies function, from cells and organs to whole-organism systems. Physiology explains how livestock grow, reproduce, digest feed, and respond to their environment.
Animal breeding : The planned mating of animals to produce offspring with desired inherited traits. Breeding applies genetics to improve traits such as fertility, growth, and disease resistance.
Veterinary medicine : The medical discipline concerned with preventing, diagnosing, and treating disease in animals. Animal science studies production and management broadly; veterinary medicine centers on individual and population health.
Animal agriculture : The branch of agriculture that raises animals and uses their products. It places animal science within the wider food and farming systems it helps shape.
Animal nutrition : The study of animals’ dietary requirements and how nutrients support maintenance, growth, reproduction, and health. Feed composition and intake directly shape animal health and production.
Livestock production : The raising and management of farm animals for food, materials, labor, or other products. It is a central setting where biological knowledge guides daily management and production choices.
Animal rights : The ethical and political view that animals have rights that constrain how humans may use them. It challenges whether breeding and raising animals for human purposes is morally permissible.
Greenhouse gas emissions from agriculture : The release of heat-trapping gases from agricultural activities, including livestock production. Animal feeding and manure management influence emissions, especially methane and nitrous oxide.
Animal genetics : The study of heredity and genetic variation in animals. Inherited traits influence productivity, disease resistance, and suitability for different production systems.
Dairy farming : The raising and management of animals, chiefly cattle, for milk production. Dairy systems apply nutrition, reproduction, genetics, and health management to milk production.
