Temperament

Most mammoth donkeys possess a good temperament and a strong work ethic. The ideal mammoth donkey doesn’t tire easily, remaining unflappable and willing. Mammoth donkeys take a while to mature but can keep going strong into old age. Avoid putting them into hard work until they are at least five years old.

Appearance

To qualify as a mammoth jackstock breeding animal, a jack must stand at least 14.2 hands; a jennet must reach 14 hands. Jacks generally weigh between 1,000 and 2,000 pounds, the jennets slightly less.

Any colour is acceptable but black, chestnut and roan are preferred by breeders of draft mules. The darker gray colour of smaller donkeys is looked down upon by breeders.

Any breeding animal should possess good conformation and strong bones.

Uses

Mammoth Jacks are still used primarily for mule production. Because mammoth donkeys are relatively rare, males are generally not gelded – they are in demand as breeding stock

Heavier jacks are crossed with draft mares to produce draft mules, while lighter animals are bred to light horse mares for saddle mule production.vMany of these mares come from gaited breeds, resulted in gaited mules. Mammoth jacks and jennets can be ridden or trained for driving.
