Information About Mules


Mule is a hybrid produced when a male donkey (jack) mates with a female horse (mare). A mule is unable to reproduce naturally because of its irregular chromosome count. Since 1500s, there have been very few exceptions where the female mules have produced foal by mating with a jack or a stallion. Mules are present in any part of the world where there is inhabitation of donkeys and horses. Mules are very useful animals and do almost all the kinds of jobs that a horse does. Their physical attributes and behaviour depend on the breed of mare and jack. Mules succeed in having all the characteristics that a horse possesses. The tolerance, sure footedness, intelligence, and drought endurance of the donkey combined with the agility, body structure, power, and nerve of the horse, makes mule an excellent working domestic animal. Handlers of working animals prefer mules over horses most of the time because mules have harder skin which is less susceptible to extreme heat or rain. A mule’s hooves are more protected from diseases and insects, and are much tougher than that of a horse.
