RV Stewards' Notice: Update regarding products containing Altrenogest

Racing Victoria wish to advise Trainers and Veterinarians that the analysis of additional batches of products containing altrenogest, performed by Racing Analytical Services Limited (RASL), have been found to contain varying levels of the anabolic steroids trenbolone and/or trendione, which are prohibited substances at all times.

The analysis of oral products has identified lower levels of trenbolone and/or trendione than the injectable products.

Racing Victoria are aware of the local rule (LR44A) introduced by Racing NSW on 13 August 2018. Racing Victoria supports a national approach on this issue and will work with Racing Australia and other Principal Racing Authorities in this regard as a matter of priority.

In the interim, Racing Victoria’s advice is to continue not to use products containing altrenogest unless and until this matter can be resolved.

As an alternative, Racing Victoria suggest the use of injectable, short acting progesterone for fillies and mares racing in Victoria. This should be administered in accordance with the manufacturer’s guidance and otherwise in compliance with the ‘one clear day’ rule (i.e. if a filly or mare is racing on a Saturday, progesterone must not be injected at any time on the Friday or the day of the race). Trainers should consult a veterinarian on the use of injectable progesterone in their fillies and mares.

Please note that the suggested use of progesterone only applies to the progesterone injection; it does not include long acting synthetic progestins.

If you have any queries regarding this matter, please contact Racing Victoria Veterinary or Integrity department on (03) 9258 4258.
