How does race horse breeding work?
The Jockey Club requires Stallions to “live cover” a mare for its foal to become a registered thoroughbred racehorse. The stallion is brought to the breeding location and cleaned as well. If everything is right and all parties ready the stud is walked up behind the mare, and he mounts her.
Do race horses breed naturally?
The only way a thoroughbred is allowed to reproduce is by “live cover”; i.e., horse-to-horse sexual intercourse. Barbaro was never able to become a father; his nagging leg injuries made it dangerous for him to even attempt mounting a mare. The Jockey Club has never allowed artificial insemination, or AI.
What makes a horse a stud?
A stallion is a male horse that is able to produce offspring. Stallions are mature male horses that are over the age of four. When a stallion is used for breeding he is also called a stud. Once a stallion becomes a father, he is also referred to as a sire.
