Thank you for your interest in the American Mammoth Jackstock Association. Within our website you will find everything you need ranging from history of this majestic breed, to articles about them, and forms and rules to register your own animals.



Here at the AMJA we've been processing registrations like crazy. We've even been receiving interest in registering animals in Mexico.

We've added a new board member: Dr. Marco Oviedo, Equine Reproductive Physiologist Specializing in Mammoth Donkey Reproduction. Dr. Oviedo reached out to us in regards to the genetics of the American Mammoth Jackstock.

I am so excited, and so thankful, to announce that very soon I will be able to devote more time to promoting the American Mammoth Jackstock Association. I will be continuing to encourage registration in order to preserve the majestic breed.

I have so many ideas for additional merchandise, and I am loving all the different colored shirts I have sold already. Be sure to check out the new hats on our store page. Thank you to everyone that has ordered!

The historical background of the Mammoth Jackstock must be preserved for future generations. Registration is the only way to track pedigrees for the future and ensure a quality animal.

I am looking forward to traveling to donkey shows and meeting all the wonderful donkeys out there, as well as their owners.

Thanks to everyone for their support. I look forward to meeting everyone.
