The Jockey Club today reported that 3,992 stallions covered 64,123 mares in North America during 2005, according to statistics compiled through Sept. 6, 2006. These matings have resulted in 36,630 live foals of 2006 being reported to The Jockey Club on Live Foal Reports received as of Sept. 6, 2006.

As in past years, The Jockey Club estimates that the reporting of live foals, at this point in time, is approximately 90 percent complete. The reporting of live foals of 2006 is 1.1 percent behind last year’s pace when The Jockey Club had received reports for 37,025 live foals of 2005 as of this time last year.

“History indicates that we’ll receive another 3,500 to 4,000 Live Foal Reports in the coming months, which will put us on track to register the 37,300 foals we previously projected for North America for 2006,” said Matt Iuliano, The Jockey Club’s vice president of registration services. “We encourage breeders who haven’t submitted their Live Foal Reports to do so as soon as possible so they can complete the registration of their foals within the one-year deadline and avoid late registration fees.”

In addition to the 36,630 live foals of 2006 reported through Sept. 6, The Jockey Club had also received 7,652 No Foal Reports for the 2006 foaling season.

The number of stallions declined 3.7 percent from the 4,145 reported for 2004 at this time last year, while the number of mares bred increased 0.1 percent from the 64,052 reported for 2004.

Iuliano emphasized that the breeding statistics are not a measurement of the live foals born in each state or province, but rather a count of state/province-sired live foals, regardless of where the foals were born. He also stressed that 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 33.2 percent of the mares reported bred in North America in 2005 and 40.3 percent of the North American live foals reported for 2006.

The 21,310 mares reported bred to 370 Kentucky stallions in 2005 have produced 14,748 live foals, a 4.3 percent increase on the 14,141 Kentucky-sired live foals of 2005 reported at this time last year. The number of mares reported bred to Kentucky stallions in 2005 increased 4.2 percent against the 20,443 reported for 2004 at this time last year.
