The annual statistics include the number of mares bred to each stallion and represent approximately 90% of the mares that eventually will be reported as bred in 2011. According to historical trends, The Jockey Club expects to receive RMBs representing an additional 3,500 to 4,000 mares bred during the 2011 breeding season.

The number of stallions declined 11.5% from the 2,186 reported at this time in 2010, while the number of mares bred fell 10.0% from the 40,576 reported at this time last year.

The number of stallions covering 100 or more mares increased from 82 in 2010 to 84 in 2011. These stallions accounted for a greater percentage of the total mares reported bred this year ó 30.6% of all mares bred in 2011 versus 26.8% of all mares bred in 2010 as reported at this time last year.

Further book size analysis shows a 2.5% increase in the number of mares bred to stallions with a book size of 100 or more in 2011 when compared to 2010 as reported at this time last year; a 32.2% drop in mares bred to stallions with a book size between 75 and 99; a 17.8% decline in mares bred to stallions with a book size between 50 and 74; an 8.0% decrease in mares bred to stallions with a book size between 25 and 49; and an 11.4% decline in mares bred to stallions with a book size fewer than 25.
