Percent Jersey Ancestry
Effective June 1, 2025, the American Jersey Cattle Association (AJCA) will include Percent Jersey Ancestry (PJA) on all official documents issued by the organization. PJA is calculated as the average of an animal’s parents’ PJA values, tracing back through the oldest ancestors in its pedigree. Moving forward, PJA will serve as the primary tool for evaluating male registry status. Specifically, bulls born after March 31, 2025, must have a Generation Count of GC {6} or higher and a minimum PJA of 94% to be eligible for registry.
