The number of Thoroughbred mares bred in Kentucky this year was up 3.7 percent or 622 mares, while the number of stallions in the state dropped from 233 to 208, according to The Jockey Club. Overall in North America, the number of mares bred held steady at just less than 35,000, with an additional 3,000 reports expected to be received for this breeding season.
Kentucky again led all states in the number of mares bred, with more than 50 percent of all North American mares bred in the state. Most of the stallions that covered 100 or more mares are standing at farms in Kentucky.
The busiest stallion of the season was Ashford Stud's Uncle Mo, who was bred to 221 mares. Next was Ashford's Scat Daddy, with 217 mares; Spendthrift Farm's Into Mischief with 210; Ashford's Shanghai Bobby, 202; and Spendthrift's Temple City, 199.
