Domesticated goats are descended from the pasang (Capra aegagrus), which is probably native to Asia, the earliest records being Persian. In China, Great Britain, Europe, and North America the domestic goat is primarily a milk producer, with a large portion of the milk being used to make cheese. One or two goats will supply sufficient milk for a family throughout the year and can be maintained in small quarters, where it would be uneconomical to keep a cow. For large-scale milk production, goats are inferior to cattle in the temperate zone but superior in the torrid and frigid zones. Goat flesh is edible, that from young kids being quite tender and more delicate in flavour than lamb, which it resembles. Some breeds, notably the Angora and Cashmere, are raised for their wool (see also wool; cashmere; Angora goat); young goats are the source of kid leather.
