The words donkey and ass are generally used interchangeably to denote the same animal, though ass is more properly employed when the animal is wild (e.g., Equus africanus or E. hemionus) and donkey for a domesticated beast (E. asinus). Wild asses inhabit arid semidesert plains in Africa and Asia where the vegetation is sparse and coarse; the domestic donkey does well on coarse food and is hardy under rough conditions, hence its usefulness to humanity as a beast of burden in places where horses cannot flourish, such as the mountains of Ethiopia and other parts of northeast Africa, the high plains of Tibet, and the arid regions of Mongolia.
The donkey’s occasional obstinacy in refusing work too heavy for it has become proverbial, but its equally proverbial stupidity is often a reaction to brutal treatment and neglect. It is naturally patient and persevering, responding to gentle treatment with affection and attachment to its master. One of the largest donkey breeds, the Mammoth Jack, was developed in the United States in the late 18th century from European imports, including the Adalusian, the Maltese, the Majorcan, the Poitou, and various Italian strains. It stands 15 to 16 hands (1.5 to 1.6 metres, or 4.9 to 5.2 feet) in height and weighs 410–520 kilograms (900–1,150 pounds) at maturity. The development of the breed was originally undertaken by George Washington and Henry Clay, among others, to produce larger, stronger mules for American industry.
The mule is produced by crossing a jackass (e.g., male donkey) with a mare. At one time many different types of mules were recognized, such as draft mules, farm mules, sugar mules, cotton mules, and mining mules, in declining order of size. The mining mule, a small rugged individual weighing as little as 270 kilograms (600 pounds), was used in pit mines. Mules are still used in some of the subtropical and tropical countries because of their ability to withstand most types of stress including heat, irregular feeding, and abuse. Mules are surer-footed than horses and are considered to be more intelligent. For that reason they are still used as saddle and pack mounts in precarious terrain. Unlike horses, mules refuse to damage themselves by overeating or by thrashing around when tangled up or in cramped quarters. The reverse cross of a stallion on a jenny (e.g., female ass) is called a hinny, which is slightly smaller than a mule; both mules and hinnies are sterile.
