This equine designation refers to a horse that is the result of a cross between a registered American Quarter Horse and a registered Thoroughbred. These horses possess a specific pedigree, linking them directly to both breeds’ bloodlines.
Such a breeding strategy aims to combine the athleticism and speed of the Thoroughbred with the stock horse qualities, versatility, and calm temperament often found in Quarter Horses. This blend can result in animals well-suited for various disciplines, including racing, jumping, and general ranch work. Historically, the registry for these crosses provided a pathway for introducing desirable Thoroughbred traits into the Quarter Horse breed while maintaining breed standards.
