Purebred Mini Jersey

Registration ​with

DNA Proven Purity

Mini Jerseys are first and foremost dairy cattle.  So, why are so many of them composed of mixed dairy and beef breeds?  It’s easy to use American Aberdeen, Galloway, or Dexter to reduce height but it comes at the expense of dairy traits.  In over 30 years Mini Jerseys hadn’t moved away from crossbreeding to reduce stature.  It’s time to look to the future and breed back to proven purity.  

More than a registry, the Purebred Mini Jersey Society wants to connect Mini Jersey owners who breed for proven pure Jersey traits in their Mini Jerseys.  Working together we can identify, register, and utilize the purest genetics.

It’s the mission of PMJS to provide Mini Jersey owners with resources to breed each generation of Purebred Mini Jersey dairy cattle better than the previous one through education, mentoring, and community.

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.
