Cow
A cow is an adult female bovine, especially one that has borne a calf. Cows produce milk and are raised for dairy, breeding, and meat production.
Cattle: Cattle are domesticated bovines raised worldwide for food, materials, and work. Cows are adult females within this broader domesticated group.
Lactation: Lactation is the production and secretion of milk by mammary glands after birth. A cow's milk supply begins through this process after calving.
Dairy farming: Dairy farming is the raising and management of animals to produce milk for human use. Dairy herds manage cows for sustained milk production.
Livestock: Livestock are domesticated animals kept for food, materials, labor, or other human uses. Cows are a major livestock species in agricultural economies.
Bos taurus: Bos taurus is the scientific species name for taurine cattle, including many familiar cattle breeds. Many cows belong to this cattle species.
Mammary gland: A mammary gland is a milk-producing organ composed of secretory tissue and ducts. The cow's mammary glands produce and deliver milk through the udder.
Beef cattle: Beef cattle are cattle raised primarily for meat rather than milk production. Some cows are kept in beef herds, unlike cows selected chiefly for dairy.
Greenhouse gas emissions from agriculture: Agricultural greenhouse gas emissions include gases released by farming, land use, and food production. Cattle contribute methane through digestion and emissions through manure and feed production.
Heifer: A heifer is a young female bovine that has not yet borne a calf. A cow is distinguished from a heifer by maturity and, typically, prior calving.
Pregnancy in cattle: Pregnancy in cattle is the gestation of a developing calf in a female bovine's uterus. Gestation links breeding to calving and the onset of lactation.
