The Jockey Club Adopts Rule Regarding Thoroughbred Stallion Breedings

The Jockey Club board of stewards today announced that it has adopted a final rule limiting the annual breeding of individual stallions. The rule reflects The Jockey Club’s goal to preserve the health of the Thoroughbred breed for the long term and will apply prospectively to stallions born in 2020 or later.

Effective today, The Jockey Club’s Principal Rules and Requirements of the American Studbook are amended by adding the following italicized language to the text of Rule 14C:

C. Based on the information on a completed Report of Mares Bred form, The Jockey Club will forward to the stallion owner, lessee or authorized agent a preprinted Service Certificate for each broodmare bred, including the name of the stallion, the name of the broodmare, the name of the dam of the broodmare, and the date of the last cover.

The total number of broodmares bred per individual stallion whose year of birth is 2020 or thereafter shall not exceed 140 per calendar year in the United States, Canada, and Puerto Rico. The Jockey Club shall limit the number of Stallion Service Certificates for such stallions to a maximum of 140 per calendar year.

When the stallion owner, lessee or authorized agent receives the preprinted Service Certificate, it should be examined for accuracy, signed by the stallion owner, lessee or authorized agent and forwarded to the breeder of the foal or submitted to The Jockey Club through Interactive Registration™ at http://www.registry.jockeyclub.com. The Service Certificate is required to register a foal. Service Certificates will not be issued unless a completed Report of Mares Bred form is on file at The Jockey Club and until genetic or re-DNA typing of the stallion has been completed (see Rule 5).

In an effort to illustrate the operation of the new rule, The Jockey Club offers the following examples of how it will be applied:

(1)  For stallions born in 2019 and earlier, there will be no limit to the number of mares reported bred in the United States, Canada, and Puerto Rico. The Jockey Club will issue stallion certificates for all mares bred by such stallions within the United States, Canada, and Puerto Rico during a calendar year.

(2)  For stallions born in 2020 and later, the maximum number of mares covered within the United States, Canada, and Puerto Rico in a calendar year will be 140. It would be a violation of Rule 14C for such a stallion to cover more than 140 mares within the United States, Canada, and Puerto Rico during a calendar year. The aforementioned limit will apply to all mares bred during a calendar year regardless of when The Jockey Club receives a Report of Mares bred (or any amendments or supplements thereto).

The Jockey Club will modify its Report of Mares Bred form and other related forms in recognition of the amendment to Rule 14. Stallion Service Certificates will be issued on the basis of first cover date in the order of mares listed on the Report of Mares Bred.

The Jockey Club is grateful for the many thoughtful comments in response to its September rule proposal. The stewards carefully considered those comments in formulating a rule that will promote diversity of the Thoroughbred gene pool and protect the long-term health of the breed.

The Jockey Club will continue to maintain the Principal Rules and Requirements of the American Studbookin keeping with its mission to ensure the health of the Thoroughbred breed.

Mares Bred in Louisiana Drops 12.5% in 2019

The Jockey Club today released Report of Mares Bred (RMB) statistics for the 2019 breeding season. Based on RMBs received through October 16, 2019, The Jockey Club reports that 1,134 stallions covered 29,218 mares in North America during 2019.

The Jockey Club estimates an additional 2,500 to 3,500 mares will be reported as bred during the 2019 breeding season.

The number of stallions declined 6.6% from the 1,214 reported at this time in 2018, and the number of mares bred decreased 3.5% from the 30,274 reported last year. Consistent with prior years’ reporting of stallions by book size, the number of stallions covering 125 or more mares increased from 62 in 2018 to 65 in 2019.

Further book size analysis shows a 6.7% increase in the number of mares bred to stallions with a book size of 125 or more in 2019 when compared to 2018 as reported at this time last year; a 9.1% decrease in mares bred to stallions with a book size between 100 and 124; a 9.1% decrease in mares bred to stallions with a book size between 75 and 99; a 16.7% decrease in mares bred to stallions with a book size between 50 and 74; a 12.4% decrease in mares bred to stallions with a book size between 25 and 49; and a 1.0% increase in mares bred to stallions with a book size fewer than 25.

The percentage of broodmares covered by stallions serving 125 or more mares increased from 31.9% in 2018 to 35.3% in 2019. From 2015-2017, this percentage had remained fairly constant at approximately 29%, up from 20.5% in 2014.

The proportion of stallions with book sizes of 125 or more mares grew from 5.1% in 2018 to 5.7% in 2019. It had previously grown from 3.1% in 2014 to 4.5% from 2015-2017.

2014 2015 2016 2017 2018 2019
% stallions with book size >125 3.1% 4.5% 4.5% 4.5% 5.1% 5.7%
% mares covered by stallions with book size >125 20.5% 29.1% 28.7% 29.4% 31.9% 35.3%

Note: Statistics summarized as of October 16 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 2019 are available through the Fact Book section of The Jockey Club’s website at jockeyclub.com.

The stallions Justify and Mendelssohn led all stallions with 252 mares bred by each in 2019. Rounding out the top five by number of RMBs were Into Mischief, 241; Uncle Mo, 241; and Goldencents, 239.

Kentucky traditionally leads North America in Thoroughbred breeding activity. During 2019, Kentucky’s 220 reported stallions covered 17,123 mares, or 58.6% of all of the mares reported bred in North America. The number of mares bred to Kentucky stallions decreased 1.1% percent compared with the 17,322 reported at this time last year.

Of the top 10 states and provinces by number of mares reported bred in 2019, Pennsylvania and Oklahoma stallions covered more mares in 2019 than in 2018, as reported at this time last year. The following table shows the top 10 states and provinces ranked by number of mares reported bred in 2019:
