Research into crossbreeding of Angus and Brahman stock was begun in about 1932 at the Iberia Livestock Experiment Station of the Agricultural Research Service of the United States Department of Agriculture near Jeanerette, Louisiana, where crossbreeding of Brahman and Shorthorn cattle had already shown good results.[5]: 205 It was hoped that the good adaptation of the Brahman to hot and humid conditions could be combined with the better meat qualities of the Angus, as well as its black coat and polled characteristic.[5]: 206 An ideal proportion of 5/8 Angus to 3/8 Brahman was established. By 1949 the cattle were distributed in sixteen American states and in Canada.[5]: 207 A breed society, the American Brangus Breeders' Association, was formed in that year; it later became the International Brangus Breeders' Association.[5]: 206
In 2016 the Brangus was present in twenty-six American states.[4]: 138 The population reported for the United States in 2010 was 42702;[4]: 138 in 2017 it was 30000.[2]
It has been exported to many countries, particularly in South America.[5]: 207 It is reported (without distinction from the Australian Brangus) from twenty countries, with large populations in Brazil, Mexico and South Africa.[6]
