AboutDon Boddie Expertise All aspects of the thoroughbred breeding and racing industry in New Zealand. I race thoroughbreds and have been the Marketing Manager for three NZ racing clubs. If I don`t know the answer to your question I know someone who does!
Experience 20 years in the racing industry. Currently focusing on breeding but involved in all aspects of the industry. Ive raced several thoroughbreds with modest success and have had great fun out of it.
Answer Hi Joe,
A most unusual question for this type of forum, however I'll assume its serious.
I don't know about US racing rules or common practice in US racing but it certainly would not be allowed in NZ or Australia.If it is a possibility that the mare will 'slip' the foetus then she should not be racing.
The best person to ask would be a vet.
I hope this helps,
