Composite breed
A breed founded by crossing two or more breeds and then breeding the crosses together until the type is fixed.
Also: synthetic breed, stabilised crossbred, composite
A composite breed is made on purpose from a planned mix of existing breeds. Breeders cross the founding breeds, then mate the crossbred animals with one another over many generations, selecting for the type they want until it breeds true and can be registered in its own herd book. Many of the best-known composites join zebu hardiness to taurine meat or milk. The Santa Gertrudis of Texas, recognised in 1940, is about three-eighths Brahman and five-eighths Shorthorn; the Brangus is three-eighths Brahman and five-eighths Angus; South Africa's Bonsmara and India's Karan Fries and Frieswal are others. Composites aim to keep some of the hybrid vigour of a first cross in a breed that is easier to manage.
