O’Briens’ Australian Team Tested by RV

Australian runners trained by Aidan and his son Joseph O’Brien have undergone tests by Racing Victoria to see if they came back positive for the synthetic substance Zilpaterol, which had been found in contaminated GAIN feed. Both O’Briens and Aidan’s other son Donnacha were forced to scratch all of their runners on Arc Sunday after they tested positive for the substance. The O’Briens’ 10 horses arrived in Melbourne on Friday night and are under quarantine for two weeks at the International Horse Centre in Werribee.

A statement by Racing Victoria said in part, “Following discussions with the O’Brien stables, RV stewards have today conducted out of competition testing on their horses at Werribee to determine whether zilpaterol is currently in any of the horse’s systems. The results of these tests may take up to one week. Furthermore, both stables have confirmed to RV stewards today that they have ceased using feed from the provider in question.

“RV stewards will continue to work with the O’Brien stables regarding the situation and will make a further comment once the result of the out of competition tests are known and the stables have been notified.”

O’Brien Family Runners Withdrawn From Sunday’s Arc Card Due To Zilpaterol Positives, Possible Feed Contamination

A total of 11 horses trained by Aidan, Joseph, and Donnacha O'Brien will be withdrawn from Sunday's Prix de l'Arc de Triomphe card at Longchamp after a French lab returned positive urine samples for the banned substance Zilpaterol, Racing Post reports.

Four of the O'Brien runners – Mogul, Japan, Sovereign and Serpentine – were set to test Enable in the Group 1 Arc. Fancy Blue, a leading contender for the G1 Prix de l'Opera trained by Donnacha O'Brien, will also scratched.

The withdrawals were announced after Gain Equine Nutrition advised customers to stop using its feed after some batches were found to have been contaminated with Zilpaterol, a substance that's unlicensed in Europe, but is used in the U.S. and elsewhere, primarily to promote weight gain in cattle.

Urine samples from the O'Brien horses were cleared by the Irish Equine Centre, but Aidan O'Brien told Racing Post that a difference in testing methods between the Irish and French laboratories might have produced different results. O'Brien said the Irish test is primarily used to find the drug in cattle, instead of horses.

The Zilpaterol contamination had already caused five positives in France over the past few weeks, and trainer Roger Varian, who also uses Gain products, scratched all seven of his British runners on Saturday, as well.

In 2013, feed made in a California mill and contaminated with Zilpaterol caused a rash of positives in that state, and reached as far as Hong Kong when the feed shipped overseas.

Gain is one of the most widely-used feeds in England and Ireland, meaning a large portion of their racing populations could be exposed to the contaminated feed. However, Racing Post reports that John Gosden, trainer of top Arc contender Enable, does not feed Gain products, thus the mare is not at a risk to scratch due to the contamination.

A statement from the Ballydoyle Twitter account on Saturday read:

“Unfortunately, the results of the urine samples taken from the horses yesterday have come back positive from the French laboratory. There is a possibility that the contaminant may have left their system by the time of racing tomorrow, however we have no guarantee of this, and in order to protect the integrity of racing, we have decided to withdraw all our horses from racing tomorrow. Joseph and Donnacha O'Brien will do likewise.”

O’Brien Arc Runners Tested After Possible Feed Contamination

A handful of positive tests for the prohibited substance Zilpaterol in France has led to an investigation of the products of equine nutrition company GAIN after it was found that all five affected horses had been fed the company’s products. Testing of GAIN products subsequently returned positive results for Zilpaterol. Zilpaterol is a synthetic substance used to promote weight gain in cattle.

The products in question as stated by France Galop are racehorse cubes, racehorse mix and opti-care balancer. GAIN has advised customers to cease feeding its products while an investigation is undertaken.

A statement from GAIN said that Zilpaterol “has never formed part of any formulation in any of our animal nutrition ranges.” Martin Ryan, Head of GAIN Equine, said, “We apologise sincerely to our valued customers for the inconvenience caused by this incident and we are committed to promptly keeping you fully informed. A thorough investigation and trace back of all feed ingredient sources is underway as a matter of urgency to determine how this external contaminant could have found its way into some batches of our equine product.”

Trainer Aidan O’Brien told Racing Post on Friday evening that he feeds GAIN, but that all of his horses had been switched to a different brand of feed on Thursday evening immediately after he had received the news. O’Brien has sent blood and urine samples from all his runners in France this weekend to be analysed and is hoping to receive results by Saturday evening.

“They say after a day and a half or two days, the substance should be gone out of the horse’s system,” O’Brien told Racing Post. “So, if, when we get the results, there is a trace of the substance in it, we’ll have to see how much is there and then make a decision, after changing the feed for two days, whether we should run on Sunday or not. The experts are telling us that it should be clear by then, so we’ll just have to see.”

O’Brien said he plans to go ahead with his two runners at ParisLongchamp on Saturday, Mythical (Fr) (Camelot {GB}) and Passion (Ire) (Galileo {Ire}).
