The California Horse Racing Board's Rule 1867.1, which becomes effective July 1, prohibits the administration of bisphosphonates to any horse within a facility regulated by the CHRB and also prohibits any horse from entering the grounds that has been administered the drug within six months. This means that any horse administered bisphosphonates since Jan. 1, 2020, will not be permitted within any CHRB-regulated facility (racetracks and training centers) within a six-month period of such administration.
Additional information on bisphosphonate use in race horses is available on the CHRB website (www.chrb.ca.gov) under both the Racing Safety and Veterinary sections.
