There are more than 40 million donkeys in the world, mostly in underdeveloped countries, where they are used principally as draught or pack animals . Working donkeys are often associated with those living at or below subsistence levels . Small numbers of donkeys are kept for breeding or as pets in developed countries . </P> <P> 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 . </P> <P> Asses were first domesticated around 3000 BC, probably in Egypt or Mesopotamia, and have spread around the world . They continue to fill important roles in many places today . While domesticated species are increasing in numbers, the African wild ass is an endangered species . As beasts of burden and companions, asses and donkeys have worked together with humans for millennia . </P>
