Recent decisions by the American Jersey Cattle Association (AJCA) board have made
deciphering Jersey registrations easier. With the March 2016 board action, the AJCA simplified
the registration recording process. The two major changes are the incorporation of Generation
Count and Breed Base Representation (BBR).
Under the new Generation Count system, you will no longer see OA, PR and GR or J-levels on
papers. Instead, there will be a straight numeric counting system following the animals full
registered name representing the point at which the animal was first recorded in the AJCA herd
book. This new system starts with a ‘1’ designation and moves through a ‘6’ before no designation
is needed on a pedigree.
The graph below lays out how generation counts will be handled for resulting offspring of
generational sires. The general rule of thumb is to add one count to the dam’s generational level.
