Donkeys can intersect with other members of the horse kind, and are often crossed with horses. Some large breeds of asses of Martina Franca, as Donkey, the Baudet de Poitou and Mammoth Jack are only generated for the production of a mule. The hybrid between a stallion and a donkey is a mule, and is less common.

The ancestors of the modern donkey are the Nubian and Somalian subspecies of African wild ass. Remains of domestic donkeys from the fourth millennium BC, were found in Lower Egypt in Maadi, and it is believed that the domestication of the donkey has long been in the seventh and eighth millennium BC after the domestication of cattle, sheep and goats. By the end of the fourth millennium BC, the donkeys had spread to Southwest Asia, and the main breeding center was transferred to Mesopotamia from 1800 BC. With the second millennium BC, the donkey was brought to Europe, was introduced at the same time, as probably the wine, like the donkey with the Syrian god of wine, Dionysus is associated.

The first donkey North America, as the two met in Mexico by Juan de Zumarraga, the first bishop of Mexico, where the six arrived in December 1528, during the first donkey to reach what are now the United States across the Rio Great were with Juan de OƱate in April 1598, the donkey used as a workhorse for at least 5,000 years. After the human work, the donkey is the cheapest form of power farm. Donkeys are often associated with working with the residents at or below the subsistence level. Some cultures that forbid women to donkeys to work with oxen in agriculture does not extend that taboo, so they can be used by both sexes.

Some donkey or cow meat in Italy, which has the highest consumption of horse meat in Europe and where donkey meat is the main component of several regional courts, some 1,000 donkeys were slaughtered in 2010, which is about 100 tons of meat. Donkeys work must be shod. Donkey shoes are similar to horseshoes, but usually smaller, and without toe clips.

The donkey has a tough digestive system in which roughage effectively distributed through microbial activity hindgut fermentation in the cecum and colon. While there are significant structural differences between the gastrointestinal tract of a donkey and a horse, a donkey is more efficient digestion. Donkeys are also less susceptible to colic. The reasons for this difference are not fully understood, the donkey may have different intestinal flora on the horse, or have a longer retention time of the intestine. Donkeys obtain most of their energy from carbohydrates structural. In a lush climate, donkeys are prone to obesity and are at risk of laminitis. Around the world with free donkey work very poorly associated with the residents at or below the poverty line.

In temperate climates, the food available is often too rich and too fat, overfeeding can cause cause weight gain and obesity and metabolic disorders, as the founder (laminitis) and hyperlipidemia or gastric ulcers A male donkey (jack) with a female horse can be crossed to produce a mule. A male donkey with a female horse can be crossed to produce a mule. Horse-donkey hybrids are almost always sterile because horses have 64 chromosomes, while donkeys are 62, the production of offspring with 63 chromosomes. Mules are much more common than mules.  The above terms refer generally to the production of hybrid breeding a male zebra to a female donkey. Zebra mules, and zebret zebrinny all refer to cross a zebra with a male ass woman. Zebrinnies zedonkies because they are more rare than precious female zebras in captivity, when the production of purebred zebras there are not enough female zebras breeding in captivity, in order to save for hybridization, there is no such restriction on the number of women farm donkeys.
