To be eligible to be entered or to start in races exclusively for horses foaled in New Jersey, each horse must be registered with the Standardbred Breeders Association of New Jersey. To qualify for such registration the said horse must have been dropped by a mare in the State of New Jersey. "Breeder" of a horse is the owner of its dam at the time of foaling.
