The Aidan O’Brien stable will need to wait a few more days for test results on its spring raiders

The fate of Aidan O’Brien’s latest Spring Carnival challenge is likely to be clearer at the end of the week.

The Irish master’s Australian team was thrown into turmoil after revelations that his horses could have been fed from a contaminated batch of feed before travelling to Australia.

O’Brien withdrew his horses from the rich Prix De l’Arc de Triomphe meeting in France on the weekend after tests revealed the presence of the substance zilpaterol.

Zilpaterol is a substance used in the US to aid cattle growth but can assist with any airway issues in horses. Zilpaterol is legal for use on horses but they cannot race with the drug in their system.

Racing Victoria vets took samples from horses trained by O’Brien and his son Joseph at the Werribee Quarantine Centre on Monday.

RV’s integrity boss Jamie Stier told RSN some of Joseph O’Brien’s four-horse team were on the same feed as Aidan’s Melbourne runners. Aidan O’Brien’s Melbourne team included leading Caulfield Cup chance Anthony Van Dyck.

“We’re hopeful of having those results back before the week’s end,” Stier said.

“My information from Joseph is that of the horses that are down here, some have been fed Gain products and others have been fed Red Mills.

“Immediately this issue came to light, Joseph transferred all his horses off Gain products and put them on Red Mills products.”

Stier said he was unsure whether Anthony Van Dyck could run in Saturday week’s Caulfield Cup if the horse tested positive for Zilpaterol.

He said it would depend on the amount of the drug the horse ingested.

“We we’re told it’s a contaminant in the feed, we don’t know the dosage rates that have been consumed and you don’t know whether it’s consistent contamination across the whole batch,” Stier said.

“That’s why it’s important that we get the analytical data so to work how best to proceed with this matter.”

Stier said British and Irish racing authorities were in touch with Racing Victoria about the progress of their investigations into the problem.
