Over 1000 breeds of cattle are recognized worldwide, some of which adapted to the local climate, others which were bred by humans for specialized uses. Beefalo is an American breed with bison genes, Heck cattle is a hardy breed of domestic cattle, while the Brangus is an American hybrid breed of beef cattle derived from cross-breeding of American Angus and Brahman stock. However, Oregon Blue is not a cattle breed but a type of blue pigment discovered in 2009.
