The Simmental is replacing the Hereford for crossng on dairy herds. To improve the productivity of the Hereford, bulls of the Canadian strain have been imported. The objectives of the present work were (1) to compare the growth and carcass composition of Friesian, Canadian Hereford x Friesian and Simmental x Friesian steers, and (2) to determine the effects of two levels of supplementary concentrates during finishing, and duration of the finishing period on carcass weight and composition.
