American Mammoth Jackstock
American Mammoth donkeys
|Other names||Mammoth Jack (males)|
|Country of origin||United States|
The American Mammoth Jackstock is a breed of North American donkey, descended from large donkeys imported to the United States from about 1785. George Washington, with Henry Clay and others, bred for an ass that could be used to produce strong work mules. Washington was offering his jacks for stud service by 1788. Large breeds of asses were found in Kentucky by 1800.
Breeds that influenced the Mammoth Jack include the Maltese, the Baudet du Poitou, the Andalusian, the Majorcan and the Catalan. Jacks (entire males) must stand at least 14 hands (56 inches, 142 cm), and jennies or jennets (females) at least 13.2 hands (54 inches, 137 cm). Any American donkey over these minimum heights may be registered with the American Mammoth Jackstock Registry.
