Greyhound trainers are now permitted to use norethisterone as a legitimate seasonal suppressant in racing bitches when prescribed by a veterinary surgeon and recorded properly in their GBGB treatment book.
This “significant development in the regulation of greyhound racing” was announced at a special seminar hosted by the Greyhound Board of Great Britain (GBGB), the governing body for licensed greyhound racing.
Speaking at the seminar VMD chief executive Steve Dean said: “Following discussions with GBGB, it is clearly recognised that products currently licensed for canine oestrus suppression may affect the health or performance of the racing greyhound bitch. I am satisfied that considered use of norethisterone, as prescribed by a veterinary surgeon, meets the requirements of the cascade and is therefore a candidate for oestrus suppression when authorised products do not produce a satisfactory clinical outcome.
“Veterinary surgeons are able to prescribe norethisterone under the cascade using their professional clinical judgement. We expect both veterinary surgeons and trainers to maintain proper records of the prescription and use of the medicine – which must have a UK authorisation for human use – and strongly encourage any adverse affects to be reported to VMD so we can develop our knowledge and understanding of norethisterone use in practice.”
According to GBGB veterinary director Simon Gower, bitches will typically require 2.5mg (or half a tablet) of norethisterone daily. Suppression of a bitch using this drug is therefore likely to cost in the region of £5 per month.
Mr Gower said: “It was clear that all present at the seminar were in agreement that the introduction of norethisterone represents a positive development for the sport.”
