Brangus

The USDA research herd behind the breed ran at the Iberia Livestock Experiment Station of the USDA's Agricultural Research Service, near Jeanerette. The American Brangus Breeders Association formed in 1949 and later became the International Brangus Breeders Association, which holds the registry today.

Polled and black, at the fixed five-eighths Angus, three-eighths Brahman ratio. The design goal is written into that ratio: the Brahman's adaptation to hot, humid conditions carried alongside the Angus's meat quality. The US population was reported at about 30,000 head in 2017, spread across 26 states, with large populations in Brazil, Mexico and South Africa.

The International Brangus Breeders Association does not leave temperament to reputation. Its registration terms define a temper score that runs from 1, gentle and easily handled, to 6, extremely aggressive, and its records carry a code for animals culled on temperament. An extension beef cattle specialist, in an article the association published, calls disposition heritable and says it is best managed by culling wild cattle from seedstock and commercial herds alike, because wild cattle are more likely to hurt someone.

The Brahman side matters here. University of Missouri Extension says cattle with Bos indicus breeding are often more excitable during handling than Bos taurus cattle, so ask what disposition data stands behind the animals you are buying.

Whatever the score, Cornell's general guidance on beef cattle safety holds: a cow with a newborn calf can be very aggressive, so avoid walking between her and the calf, and no bull can be trusted.

The point of the three-eighths Brahman, five-eighths Angus ratio is that it keeps most of the Brahman's heat tolerance, insect resistance and longevity while keeping enough Angus for marbling, calving ease and a polled, black-hided calf.

They suit the Gulf Coast, the Southeast and anywhere the summer is the limiting factor.

Heat is the point of the breed. The association says it combines heat tolerance with carcass merit, and Texas A&M AgriLife's breed table rates Brangus a 3 for heat tolerance, against 4 for the Brahman and 1 for the Angus. The same publication notes that cattle tolerant of hot climates are relatively less adapted to cold, so the advantage narrows in colder country.

The association promotes Brangus and Brangus-cross commercial females for heat and parasite resistance, calving ease and maternal traits. Because Angus is one of its parents, it also tracks the Angus-derived recessive conditions, arthrogryposis multiplex (AM) among them, so ask for the test status of any breeding animal.

The trade is that a fixed fraction is a compromise by design. A Brangus will not tolerate heat as well as a purebred Brahman and will not marble as well as a purebred Angus, and if your climate does not actually require the Brahman half, you are paying for it anyway.

Registration runs through the International Brangus Breeders Association. Red Brangus is a separate breed with its own association; do not assume one set of papers covers the other.
