The domestic goat (Capra aegagrus hircus) is a subspecies of goat domesticated from the wild goat of southwest Asia and Eastern Europe.
The goat is a member of the family Bovidae and is closely related to the sheep as both are in the goat-antelope subfamily Caprinae. There are over 300 distinct breeds of goat. Goats are one of the oldest domesticated species, and have been used for their milk, meat, hair, and skins over much of the world. In 2011, there were more than 924 million live goats around the globe, according to the UN Food and Agriculture Organization.
Female goats are referred to as “does” or “nannies”, intact males are called “bucks” or “billies” and juveniles of both sexes are called “kids”. Castrated males are called “wethers”. While both the words “hirsine” and “caprine” refer to anything having a goat-like quality, the former is used most often to emphasize the distinct smell attributed to domestic goats.
