Registration Requirements

Requirements for Recording and Certification

Purebred Mini Jersey Society is an OPEN Herd Book.  This means, that if your Mini Jersey meets the requirements, even if they, their sire or dam, were never registered, you may apply.  If you aren’t sure if your cows qualify, contact us.  Let’s talk about it.  It’s our desire to identify and record the purest Mini Jerseys in the PMJS Herd Book.  The PMJS Breed Standard is public.  It’s our hope it will be referred to and utilized by anyone breeding a Mini Jersey.

​Membership in Purebred Mini Jersey Society is required to Register cattle in the PMJS open Herd Book.  

Registration requires genomic testing and results recorded with Purebred Mini Jersey Society.  Genomic testing* with BBR85+ must be provided and made available to Members through Purebred Mini Jersey Society before a permanent registration certificate will be issued.  (You may block out a physical or mailing address.)  The price for testing of females is currently $47 for the LD 100k test.  The Council on Dairy Cattle Breeding (CDCB) charges an additional $100 fee for Mini Jersey bulls born in the USA to utilize the test.  There is a less expensive route for bull owners.  To learn more, visit the Go 4 the Gold! page

The registration number issued by the American Jersey Cattle Association (AJCA) is recognized by the CDCB and USDA as a tracking number for each individual animal for the purposes of issuing Health Certificates and federally regulated disease testing (tuberculosis, brucellosis, etc.).  Bulls collected for artificial insemination can also use the National Association of Animal Breeders (NAAB) stud code found on the AI straw.

Proof of Negative Dexter Cattle BD1/Bulldog Dwarfism/Chondro testing* from UC Davis is required for registration.  Either a copy of testing from both parents or a copy of testing can be provided for the animal being recorded.  This test is $25 as a stand-alone and less if ordered in the DNA/A2/Diagnostic Package from the Veterinary Genetics Laboratory at UC Davis.

Black Registration Certificate

BBR85+ and under 3 Yrs = Black Registration Certificate

A temporary Black Certificate is awarded for Purebred Mini Jerseys:

Upon reaching their third birthday, and providing a Height Verification Form, the Black Certificate can be exchanged for FREE for a Gold, Silver, or Bronze Certificate, if all requirements are met.

Verified Breeding Stock Certificate

Cows and heifers must meet all other requirements for registration with the exception of either BBR80-84 or height to the top of the hip of 45.25″ to 48″.  This establishes a new bloodline and increases genetic diversity in the gene pool.  These animals are not registered with PMJS but will be used in a Purebred Mini Jersey breeding program.  Bulls are not eligible for Verified Breeding Stock Certification.

A permanent ROSE GOLD Certificate is awarded for PMJS Verified Breeding Stock with a waiver for either height or purity:
– Over three years old
​​- Conforms to Breed Standard
– Height Verification Form
– Proof of BBR80-84 with a waiver for purity (must be under 45″ in height)​
– Mature height of 48″ or less with a waiver for height (must be BBR85-100)
​- Proof of Negative Dexter Cattle Bulldog Dwarfism/Chondro status
– Parental Verification DNA match may be required

If your cattle do not meet the minimum requirements, we encourage you to contact us about working with them as a developing bloodline.  In many situations, this can lead to future offspring being registerable.
– Added as “Reference Only” so all offspring can be linked within the Purebred Herd Book
​- Not required to conform to Breed Standard
– Not required to have a height below 45″ or Breed Based Representation (BBR) of 85 or above
– Proof of negative Dexter Cattle Bulldog Dwarfism/Chondro status is preferred
– May be tightly line-bred or in-bred
– Cannot contain Bos Indicus derived varieties, such as Zebu
​We’re happy to provide your cattle with a free online profile so their registered offspring within the PMJS Herd Book can be linked.
