The American Brahman is a zebuine-taurine hybrid beef cattle breed developed in the United States beginning in 1885 from cattle originally from India. Foundation stock included mainly Gir, Guzerá and Nelore animals, imported at various times from the United Kingdom, India and Brazil.
The first zebuine cattle arrived in the United States in 1849, when a single bull of Indian origin was imported from the United Kingdom to South Carolina. The more deliberate breeding program began in 1885 when a pair of grey bulls were brought directly from India to Texas.
The name "Brahman" was chosen by J. W. Sartwelle, secretary of the American Brahman Breeders Association. The association was formed in 1924, the same year a herd-book was established for the breed.
Brahman meat is generally considered lower in quality than that of specialized European beef breeds, so crossbreeding allows ranchers to combine the Brahman's heat tolerance and parasite resistance with the meat quality of European breeds. The crossbred offspring also benefit from heterosis, or hybrid vigor.
Exports of Brahman cattle to Australia began in 1933 and totaled only 49 head by 1954. By 1973, their descendants numbered more than 225,000. Additional imports of around 700 head came after 1981, and by 1987 Queensland alone held over a million Brahman. By the end of the twentieth century they outnumbered any other breed in Australia.
Several Brahman crosses are established as separate breeds, including the Brangus (Brahman x Angus), Brahmousin (Brahman x Limousin), and Simbrah (Brahman x Simmental). Other crosses such as the Braford, Bravon and Bra-Swiss exist but have not achieved formal breed status.
