The mule is a domestic equine hybrid between a donkey and a horse.It is the offspring of a male donkey (a jack) and a female horse (a mare). [1] [2] The horse and the donkey are different species, with different numbers of chromosomes; of the two possible first-generation hybrids between them, the mule is easier to obtain and more common than the hinny, which is the offspring of a male horse ...
The Baudet du Poitou, also called the Poitevin or Poitou donkey, is a French breed of donkey. It is one of the largest breeds, and jacks (donkey stallions) were bred to mares of the Poitevin horse breed to produce Poitevin mules, which were formerly in worldwide demand for agricultural and other work.
A hinny is a domestic equine hybrid, the offspring of a male horse (a stallion) and a female donkey (a jenny). It is the reciprocal cross to the more common mule, which is the product of a male donkey (a jack) and a female horse (a mare).
It is the product of mating between a Baudet du Poitou jack or donkey stallion with a mare of the Poitevin Mulassier breed of draught horse. Mule production was an important industry in Poitou for three hundred years or more, and the number of mule foal births may have reached 30,000 per year.
Poitevin mares were put to jacks of the large Baudet du Poitou breed of donkey; the resulting Poitevin mules were in demand for agricultural and other work in many parts of the world, including Russia and the United States. [4]: 271 In the early twentieth century there were some 50,000 brood mares producing between 18,000 and 20,000 mules per year.
Breeding of different branches of the equine family, which does not occur in the wild, generally results in sterile offspring. The combination of sire and dam also affects the offspring phenotype. A zorse is the offspring of a zebra stallion and a horse mare. This cross is also called a zebrose, zebrula, zebrule, or zebra mule.
the Poitou donkey was developed for the sole purpose of the jacks being mated with mares to produce mules. It is a large donkey breed with a very long shaggy coat and no dorsal stripe: Benderi: Iran: Biyang: China: Bourik: Haiti: Brasil: Venezuela: Bulgaro: Venezuela: Bulgarian donkey: Bulgaria: Burro: Mexico, Nicaragua, United States
A male donkey (jack) crossed with a female horse produces a mule, while a male horse crossed with a jenny produces a hinny. Horse–donkey hybrids are almost always sterile because of a failure of their developing gametes to complete meiosis. [88] The lower progesterone production of the jenny may also lead to early embryonic loss. In addition ...
