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 encouraged to report that I have been blessed to be able to devote more time to the American Mammoth Jackstock Association. This will enable me to quickly process and return registration certificates. I will be continuing to encourage registration in order to preserve the majestic breed. Not only does registration help with preservation of the breed, it also adds value to stock. It is beneficial in so many ways.

I have so many ideas for additional merchandise, and I am loving all the different colored shirts I have sold already. I am currently working with a screen-print designer to create an embroidered cap. I will give updates when that becomes a reality. 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. A registration by measurement today becomes a traceable pedigree in future generations.

Unfortunately, donkey shows are being canceled. I am sure I share the disappointment as much as those donkey owners that were looking forward to showing their beautiful animals. I am thinking positive thoughts for the future.

Thanks to everyone for their support.
