The donkey or ass is a domesticated member of the horse family, Equidae. The wild ancestor of the donkey is the African wild ass, E. africanus.
A male donkey or ass is called a jack, a female a jenny or jennet; a young donkey is a foal. Jack donkeys are often used to mate with female horses to produce mules; the biological “reciprocal” of a mule, from a stallion and jenny as its parents instead, is called a hinny.
Donkeys vary considerably in size, depending on breed and management. The height at the withers ranges from 7.3 to 15.3 hands, and the weight from 180 to 1,060 lbs.
Donkeys are adapted to marginal desert lands. Unlike wild and feral horses, wild donkeys in dry areas are solitary and do not form harems. Each adult donkey establishes a home range; breeding over a large area may be dominated by one jack. The loud call or bray of the donkey, which typically lasts for twenty seconds and can be heard for over three kilometers, may help keep in contact with other donkeys over the wide spaces of the desert. Donkeys have large ears, which may pick up more distant sounds, and may help cool the donkey’s blood. Donkeys can defend themselves by biting, striking with the front hooves or kicking with the hind legs.
A jenny is normally pregnant for about 12 months, though the gestation period varies from 11 to 14 months, and usually gives birth to a single foal. Births of twins are rare, though less so than in horses. About 1.7 percent of donkey pregnancies result in twins; both foals survive in about 14 percent of those. In general jennies have a conception rate that is lower than that of horses.
