The MHBA functions as an informational resource for horse breeders and owners, the media, community and governmental organizations, and the general public. As a service organization, the MHBA provides industry information, educational opportunities and legislative representation to its nearly 500 breeder-owner members, which include Thoroughbred breeders, owners of racehorses, steeplechase and hunt enthusiasts, and others with horse involvement. The main purposes of the MHBA have always been to educate, promote, and encourage the horse breeding industry in Maryland. While emphasis traditionally has been placed on the production of Thoroughbred race horses, the MHBA encourages all sports relating to the use of horses.
