Abstract
SUMMARY: Body composition of 324 steers from Angus dams by ten different sire breeds was compared at constant age. Progeny of the large European breeds and the Friesian attained heavier fasted live weights and carcass weights than the local Angus and Hereford breeds. Friesian cross-breds had the lowest dressing percentage. The Blonde d'Aquitaine and Limousin crosses had the lightest bone weights and this was reflected in high meat yields. The European breeds had the leanest carcasses, the traditional beef breeds the heaviest subcutaneous fat weights and the dairy breeds the heaviest internal fat weights. The results are discussed in relation to overseas findings.
