The goal of the American Mammoth Jackstock Association is to preserve the genetics of the Jackstock that were present years ago. This organization has been present since 1888, and with the efforts from many individuals throughout history, it is still active even though the need for Jackstock has diminished.
The AMJA receives no government funding of any kind. Our only source of funds is the voluntary financial support we receive from generous folks like you. And BECAUSE of that support, we will be able to preserve historic archives and preserve the breed for the future. Without this support, this wonderful breed of donkey will be lost.
The American Mammoth Jackstock Association is a resource. We're a resource because without people using the registry to register their animals, there's no way we can determine that there are still American Mammoth Jackstock out there.
The American Mammoth Jackstock is a resource. The breed is a resource to support the production of quality donkeys not only to preserve the heritage breed but also to produce quality mules for a variety of uses. From trail riding mules to teams of mules used to pull wagons or cultivate fields, the Mammoth Jack is an invaluable asset to American culture. The mule was an instrumental piece in the early development of America.
Mules, by definition, have many advantages over horses. Mules have harder hooves, are better suited to cover rocky terrain, easier to train, can travel longer distances in a day, need less sleep, live longer and have amazing strength and endurance. They are extremely sure-footed and make excellent trail riding mounts over all kinds of terrain. Mules are the chosen mount for riding in the Grand Canyon. Mules are less spooky than horses and much better suited to travel rough terrain Because of the chromosomal differences between a horse and a jack, mules for the most part are unable to reproduce. Due to the size of the Mammoth jack when bred to a mare of similar or larger size a mule of optimal riding size can be produced.
Mammoth jacks can be bred to a variety of breeds of horse to create many different types of mules. A jack can be crossed with a draft mare to create a draft mule. Gaited and spotted mules are produced from crosses with gaited horses or with the many spotted breeds available.
The popularity of mules was initiated by the gift of two jacks to George Washington that were imported to the colonies in 1785 and 1786. Mules were already being produced in America, but the support of George Washington helped increase their popularity. Even though the role of the mammoth jack in America has changed over the last 215 years due to the modernization of agricultural machinery, and the popularity of the automobile, the jack remains a vital part of America today.
Thank you for helping save this majestic breed!
The American Mammoth Jackstock Association is committed to the preservation of this important part of history.
