Purebred Mini Jersey

Registration with

DNA Proven Purity

Mini Jerseys are, first and foremost, dairy cattle. To secure the breed’s future, the Purebred Mini Jersey Society is leading a return to pure, proven Jersey genetics.

More than a registry, the Purebred Mini Jersey Society wants to unite breeders committed to preserving dairy traits through Breed Based Representation (BBR) testing. Working together we can identify, register, and utilize the purest genetics.

Our mission is to equip the community with the education, resources, and mentorship needed to make informed breeding decisions. Together, we are preserving the breed and improving each generation.

“We joined as a Lifetime Member for the community, the knowledge bank, and access to the PMJS Board of Directors for mentoring – we are learning so much here!”

Breed Toward Purity

Registration isn’t limited to Mini Jerseys who are already 100% pure. We have to start where we are. This cute heifer was only 90% pure when her DNA was tested for Jersey Breed Based Representation (BBR). With the help of the Purebred Mini Jersey Society, you can test your cow and choose bulls to improve Jersey genetic traits in each generation while maintaining reduced stature. Cows under BBR 94 can be registered as Silver or Bronze and cattle under 3 years old are recorded with a Black Registration. Cows with BBR 80-84 can be utilized for breeding and awarded a Verified Breeding Stock certificate.
