Popis: SUMMARYConformation of carcasses from 107 Romney ewe lambs was determined using two visual scoring systems and the scores related to chemical and dissected carcass composition. The conformation system which evaluated the lateral profile of the hind leg failed to improve the prediction of carcass composition. The Meat and Livestock Commission system used in Great Britain separated carcasses on weight and fatness, the higher classes having the heaviest and fattest carcasses. After adjustment for carcass weight and fatness the higher conformation classes had the lightest bones and the heaviest weight of muscle, and some of the muscles weighed were shorter and deeper than those of the lower conformation classes.
