Summary

A study was made of the live-weight gains of four ¾-bred Brahman and four purebred Hereford steers over a 12-month period. At 950 lb live weight each animal was slaughtered, after which the carcass characteristics of the two breed types were compared.

The Herefords showed the highest live-weight gains over the whole year but during autumn, when nutritional levels were poor, the Brahmans had an advantage in average daily gain.

Although both breed types varied greatly in body conformation, there was little appreciable difference in weight distribution of joints on the carcass. A higher dressing percentage was observed in the Brahmans, this being attributed to their smaller alimentary tracts. The Brahmans had a greater carcass muscle and smaller carcass fat content than the Herefords. The necessity for fat trimming of the Hereford carcasses reduced their calculated retail value index to a level below that of the Brahmans in a market which discriminated against excess fat.

Thus it was concluded that even in a temperate climate, Brahman cattle can have a place in improving productive efficiency. Apart from the heterosis developed in crossbreeding, benefits should flow from the Brahmans superiority on poor pastures and the improved production of lean meat on their carcasses.
