The Jockey Club releases 2013Â Report of Mares Bred statistics
LEXINGTON, Ky. (Oct. 17, 2013) — The Jockey Club today released Report of Mares Bred (RMB) statistics for the 2013 breeding season. Based on RMBs received through Oct. 10, The Jockey Club reports that 1,698 stallions covered 34,174 mares in North America during 2013.
The annual statistics represent approximately 90 percent of the mares that eventually will be reported as bred in 2013. The Jockey Club expects to receive RMBs representing an additional 3,000 to 4,000 mares bred during the 2013 breeding season, according to historical trends.
The number of stallions declined 8.8 percent from the 1,861 reported at this time in 2012, and the number of mares bred fell 3.4 percent from the 35,391 reported at this time last year.
The number of stallions covering 100 or more mares increased by one, from 87 in 2012 to 88 in 2013. These stallions accounted for a greater percentage of the total mares reported bred this year — 34.0 percent of all mares bred in 2013 versus 31.9 percent of all mares bred in 2012 as reported at this time last year. RMB statistics for all reported stallions in 2013 are available through the Publications & Resources section of The Jockey Club’s website at jockeyclub.com.
Further book size analysis shows a 2.9 percent increase in the number of mares bred to stallions with a book size of 100 or more in 2013 when compared to 2012 as reported at this time last year; an 11.6 percent decrease in mares bred to stallions with a book size between 75 and 99; an 11.3 percent increase in mares bred to stallions with a book size between 50 and 74; a 15.9 percent decrease in mares bred to stallions with a book size between 25 and 49; and a 5.3 percent decrease in mares bred to stallions with a book size fewer than 25.
