The Jockey Club Releases 2017 Report of Mares Bred Statistics

The Jockey Club has released Report of Mares Bred (RMB) statistics for the 2017 breeding season. Based on RMBs received through October 17, 2017, The Jockey Club reports that 1,342 stallions covered 31,863 mares in North America during 2017.

Based upon historical reporting trends, The Jockey Club estimates an additional 2,000 to 3,000 mares will be reported as bred during the 2017 breeding season.

The number of stallions declined 5.7% from the 1,423 reported at this time in 2016, and the number of mares bred decreased 5.6% from the 33,746 reported last year. The number of stallions covering 125 or more mares decreased from 64 in 2016 to 60 in 2017.

Further book size analysis shows a 3.3% decrease in the number of mares bred to stallions with a book size of 125 or more in 2017 when compared to 2016 as reported at this time last year; a 13.0% decrease in mares bred to stallions with a book size between 100 and 124; a 27.4% decrease in mares bred to stallions with a book size between 75 and 99; a 11.5% decrease in mares bred to stallions with a book size between 50 and 74; a 14.9% increase in mares bred to stallions with a book size between 25 and 49; and a 4.7% decrease in mares bred to stallions with a book size fewer than 25.

When comparing statistics based on reports received through the same day (October 17) from previous breeding seasons, the percentage of broodmares covered by large book size (125 or more) stallions increased from 19.3% in 2013 to approximately 29% in 2015 where it has remained over the past three seasons.

The proportion of stallions with book sizes of 125 or more mares grew from 2.6% in 2013 to 4.5% in 2015. It has remained constant at that rate over the past three breeding seasons.

Note: Statistics summarized as of October 17 of the breeding seasons indicated in the columns above; as reports of mares bred continue to be received, final statistics are subject to change.

RMB statistics for all reported stallions in 2017 are available through the Fact Book section of The Jockey Club’s website at jockeyclub.com.

The stallion Into Mischief led all stallions with 235 mares bred in 2017. Rounding out the top five by number of RMBs were Dialed In, 231; American Pharoah, 214; Uncle Mo, 204; and, Bodemeister, 192.

Kentucky traditionally leads North America in Thoroughbred breeding activity. During 2017, Kentucky’s 229 reported stallions covered 17,275 mares, or 54.2% of all of the mares reported bred in North America. The number of mares bred to Kentucky stallions decreased 2.7% percent compared with the 17,750 reported at this time last year.

Of the top 10 states and provinces by number of mares reported bred in 2017, Ontario, Pennsylvania and Indiana stallions covered more mares in 2017 than in 2016, as reported at this time last year.

The Jockey Club Releases 2016 Breeding Statistics

The Jockey Club Releases 2016 Breeding Statistics
The Jockey Club reported, September 21, that 1,863 stallions covered 36,045 mares in North America during 2016, according to statistics compiled through Sept. 13, 2017. These breedings have resulted in 21,624 live foals of 2017 being reported to The Jockey Club on Live Foal Reports.

The Jockey Club estimates that the number of live foals reported so far is approximately 90 percent complete. The reporting of live foals of 2017 is down 1.7 percent from last year at this time when The Jockey Club had received reports for 21,991 live foals of 2016.

In addition to the 21,624 live foals of 2017 reported through Sept. 13, The Jockey Club also received 2,467 No Foal Reports for the 2017 foaling season. Ultimately, the 2017 registered foal crop is projected to reach 22,500.

The number of stallions declined 3.1 percent from the 1,923 reported for 2015 at this time last year, while the number of mares bred declined 2.5 percent from the 36,964 reported for 2015.

The 2016 breeding statistics are available alphabetically by stallion name through the Resources – Fact Book link on The Jockey Club homepage at jockeyclub.com.

“It is important to note that the live foals reported in The Jockey Club breeding statistics are by conception area and do not represent the state in which a foal was born,” said Matt Iuliano, executive vice president and executive director, The Jockey Club. “Breeding statistics also are not a representation of a stallion’s fertility record.”

Kentucky annually leads all states and provinces in terms of Thoroughbred breeding activity. Kentucky-based stallions accounted for 49.7 percent of the mares reported bred in North America in 2016 and 57.3 percent of the live foals reported for 2017.

The 17,912 mares reported bred to 245 Kentucky stallions in 2016 have produced 12,396 live foals, a 1.7 percent increase on the 12,184 Kentucky-sired live foals of 2016 reported at this time last year. The number of mares reported bred to Kentucky stallions in 2016 increased 1.8 percent compared to the 17,598 reported for 2015 at this time last year.

Among the 10 states and provinces with the most mares covered in 2016, only three produced more live foals in 2017 than in 2016 as reported at this time last year: Kentucky, California, and Maryland. The following table shows the 10 states and provinces, ranked by number of state/province-sired live foals of 2017 reported through Sept. 13, 2017.
