As a result of veterinary advice during an investigation into whether a yearling recently sold at an Australian public auction tested positive for a prohibited anabolic steroid, Racing Queensland (RQ) stewards have determined altrenogest is not so classified.
The conclusion was made after a sample taken from a yearling colt sold at this year’s Magic Millions January sale showed the presence of altrenogest, a progesterone hormone product typically used to regulate mares’ estrous cycles.
As a result of its conclusion, there will be no sanctions on the ability of the yearling to race.
The Australian Racing Board banned steroids in May 2014. Under that ban, a horse testing positive for steroids is prohibited from competition for one year and the person(s) administering them banned two years.
The Sydney Herald-Sun indicated that the prominent trainer purchased the yearling and said he would return the horse because of the one-year prohibition. The newspaper also said the trainer said he did not want to be unfairly associated with the medication issue should the horse test positive again.
Wade Birch, RQ general manager of stewards and integrity operations, said stewards had sought the advice of the Veterinary and Analysts Committee and a prominent Queensland professor of veterinary pharmacology to determine whether altrenogest was an anabolic androgenic steroid.
Stewards also considered the newly-introduced Australian Rule of Racing 15D and 177B(2), pertaining to the testing of horses out of competition
