The list that follows is of the all the mares that have won the honor of being named Kentucky Broodmare of the Year. Mares are selected each year by the Kentucky Thoroughbred Owners and Breeders Association. Mares are graded by the success of offspring just like stallions in regards to the Leading Sires list. The one big difference being that mares only produce one foal per year and are judged solely on that one foal rather than the overall success of their progeny. “The main criteria is that the mare be boarded in the state of Kentucky, which makes it a restricted ballot, but generally a fair one considering the quality of the mares boarding in Kentucky."
