In 2003, 108 stallions covered 100 or more mares. The 126 stallions are reported to have covered 15,971 mares, or 27.2% of all mares reported.Four stallions covered more than 200 mares, and all four stallions stand at Ashford Stud near Versailles, Ky. First-year stallion Lion Heart covered a record 233 mares this year, followed by Chapel Royal with 222. Giant's Causeway, the leading sire of 2-year-olds this year and a top 10 leading sire in North America with just two crops of racing age, covered 215 mares. Fusaichi Pegasus rounded out the double-century club with 213 mares bred this year.Ashford Stud holds seven of the top 10 spots.

The number of stallions in Florida that covered 100 or more mares was 22. California (six), Maryland (four), New York (three), and Arkansas, Louisiana, Ontario, Texas, and Utah had one each."Although we haven't received reports for about a quarter of all stallions despite the requested Aug. 1 submission date, the RMBs submitted to date indicate a continuation of the trend toward larger stallion book sizes," said Matt Iuliano, The Jockey Club's vice president of registration services. "Historically, this trend is accompanied by an increase in live foal and registration percentages which would support our previously announced forecast of 37,300 registered foals for 2006."
