The Jockey Club has released the Report of Mares Bred (RMB) statistics for the 2023 breeding season. Maryland ranked sixth among states and provinces, with 566 mares bred by 25 stallions.

Maryland stallions averaged 22.64 mares per book, ranking fourth behind Kentucky, New York and Florida in the top-10. Murmur Farm’s Blofeld once again led the way among Maryland stallions, covering 97 mares in 2023. Blofeld ranks sixth among Maryland stallions by progeny earnings this year with nearly $1.9 million (as of Oct. 27), and 10th by number of winners (27) with three crops to race. He picked up his third Maryland Million winner on Oct. 14, when Miss Harriett won the Lassie. He’s also the sire of 2023 stakes winners Alpine Mist and Beach Daze, along with graded stakes-placed Fletcher.

Northview stallions Engage (83), Uncle Lino (48), Golden Lad (37) and Great Notion (35) rounded out the Maryland top five. 

Based on RMBs received through Oct. 18, 2023, The Jockey Club reports that 867 stallions covered 26,597 mares in North America during 2023. It is estimated that an additional 2,500 to 3,500 mares will be reported as bred during the 2023 breeding season.

RMB statistics for all reported stallions in 2023 are available in the Fact Book section of The Jockey Club website.
