The rule change, which appears in Section V of the Principal Rules and Requirements of The American Stud Book, was implemented by The Jockey Club’s Board of Stewards due to the increasing number of Thoroughbred foals reported as being born in the first several days of January and a concern as to whether these foaling dates were being accurately reported.

“Our Registry staff observed a small number of foals that had been born prior to January 1, which will be registered as foals of 2006,” explained Alan Marzelli, president of The Jockey Club. “Those who choose to breed mares early may risk having foals born prior to January 1.”

Marzelli also said that The Jockey Club will continue with the field inspections in 2007.

The Jockey Club recommends that owners and breeders consult the online rules book, which is available at http://www.jockeyclub.com/registry.asp?section=3 to access the Principal Rules and Requirements of The American Stud Book.
