This edition of the Fact Book includes updates to the Reports of Mares Bred (RMBs) and Breeding Statistics sections. RMBs are now sortable by stallion name, number of mares bred, and state. The Breeding Statistics can be sorted by year and then by stallion name, mares bred, reports received, live foals, percent of live foals, and state. Both sections now have a search function and enable you to view all statistics or a certain number of statistics.
