Angus cattle are hardy, undemanding, and adaptable; they mature at around two years of age, and have a high carcass yield with marbled meat. They are good natured in comparison to several breeds, but are more aggressive than some breeds such as the Hereford. Angus are used as beef cattle and are not used for milk intended for human consumption. They are used widely in crossbreeding to improve marbling and milking ability. Angus females calve easily give birth without much stress, partly because of the small size of a typical Angus calf, and have good calf rearing ability. They are also used as a genetic dehorner as the polled gene is passed on as a dominant trait.
