Mammoth Jack Breed History
The American Mammoth Jackstock was developed in the United States dating back to the days of George Washington. They have been an important part of our American agricultural history. Geoge Washington was not only our first President, he also was a leading agricultural innovator of his time. He had a great interest in improving livestock, including the development of an American Donkey breed that was large enough to produce strong work mules.
In the late 1700’s, George Washington, along with some others, was gifted a small number of Jacks (male donkeys) and Jennies (female donkeys) from the finest European breeds. These men would breed the donkeys, along with some others that they purchased, selecting stock based on size, soundness, and strength. Thus creating the American Mammoth Jackstock breed. Due to the invention of the tractor there was a dramatic decline in the number of American Mammoth Jackstock. Unfortunately, today the breed status is listed as “critical” as stated by the Livestock Conservancy, www.livestockconservancy.org.
For your donkey to be considered a Mammoth it must be 14 hands (56″) in height for males and 13.2 hands (54″) in height for females. These requirements have been established by the American Donkey and Mule Society (ADMS), creating its registry for AMJ [American Mammoth Jackstock] in 1967.
If you have never seen a Mammoth donkey you are sure to be amazed! They have very large heads, sturdy, tall bodies and the sweetest calming eyes. Oh, and let’s not forget the ears… they are very long! They have very sweet dispositions, are extremely docile, intelligent and full of mischief. You will quickly fall in love. The Mammoth is also completely dedicated to its owner and when they bray you will think, as I do that there is no sweeter music! I must warn you now. The Mammoth Jackstock is addictive.
