The Jockey Club Releases 2009 Breeding Statistics

The Jockey Club today reported that 3,130 stallions covered 49,404 mares in North America during 2009, according to statistics compiled through Sept. 8, 2010. These matings have resulted in 27,233 live foals of 2010 being reported to The Jockey Club on Live Foal Reports received as of Sept. 8, 2010.

As in past years, The Jockey Club estimates that the reporting of live foals, at this point in time, is approximately 90% complete. The reporting of live foals of 2010 is down 14.2% from last year at this time when The Jockey Club had received reports for 31,727 live foals of 2009.

The 2010 registered foal crop projection of 30,000 takes into account that not all live foals become registered. In addition to the 27,233 live foals of 2010 reported through Sept. 8, The Jockey Club had also received 5,138 No Foal Reports for the 2010 foaling season.

The number of stallions declined 9.0% from the 3,439 reported for 2008 at this time last year, while the number of mares bred decreased 13.2% from the 56,901 reported for 2008.

The 2009 breeding statistics are available alphabetically by stallion name through the Publications and Resources link on The Jockey Club homepage at

Breeding statistics released by The Jockey Club are not a measurement of the live foals born in each state or province, but rather a count of live foals reported to date by conception area, regardless of where the foals were born. In addition, the statistics should not be taken to represent the fertility record of any one stallion.

Kentucky annually leads all states and provinces in terms of Thoroughbred breeding activity. Kentucky-based stallions accounted for 39.0% of the mares reported bred in North America in 2009 and 47.5% of the live foals reported for 2010.

The 19,252 mares reported bred to 330 Kentucky stallions in 2009 have produced 12,931 live foals, a 9.3% decrease on the 14,257 Kentucky-sired live foals of 2009 reported at this time last year. The number of mares reported bred to Kentucky stallions in 2009 declined 11.0% against the 21,620 reported for 2008 at this time last year.

Among the top 10 conception areas for live foals of 2010, only Pennsylvania stallions produced more live foals in 2010 than in 2009 as reported at this time last year. The top 10 conception areas for live foals of 2010 reported through Sept. 8 are:
