“…In keeping with the findings of other workers (Kirton and Pickering, 1967;Butler, 1957;Bowman and Hendy, 1972;Branaman et al, 1962;Butler et al, 1956) there was little effect of selecting for conformation differences on the yield of high priced cuts. Pierce (1959) has indicated that fatness level was the major factor affecting the yield of high priced cuts and reported differences of up to 15 %.…”

Ninety-six lamb carcasses drawn from six batches of lambs commercially consigned to an abattoir were analysed for characteristics which may affect their economic value. From each batch carcasses were selected in equal numbers into two classes of 'good' or 'poor' conformation according to traditional standards. Carcasses selected for 'good' conformation were heavier (P<0-05) and fatter (P<0-05), slightly shorter in carcass length and hind leg length (P<0-05), greater in circumference (P<0-001) and width (P<0-001) of the hind leg, slightly greater in muscle weight (P<0-05) but no greater in bone weight than those of poor conformation. The yield of prime retail joints was similar in the two conformation classes but the 'good' conformation class had a higher proportion of loin and rib joints and lower proportion of hind leg joint (P < 0-01) although these differences were not considered to be of commercial importance. There was a lower proportion of the carcass fatty tissue in the hind leg joint of the 'good' conformation class (P < 0-05). Muscle-to-bone ratio and area of 'eye muscle' (M. longissimus thoracis) appeared to be little affected by selecting for conformation differences. Depth of fleshing as indicated by the weight of muscle in the hind leg per 10 cm length, was 40 g (6 %) heavier in the carcasses of the 'good' conformation class. This contrasted with the much greater differences, between batches, of 290 g (40 to 50 %). Between batches there were significant differences for all the measures taken except the yield of preferred retail cuts. In the main the batch differences were greater and commercially more important than the conformation class differences.

“…There is some evidence that at the same carcass weight and fatness, carcass conformation has little or no influence on percentage of high value cuts in the carcass (Butler, Warwick & Cartwright, 1956;Butler, 1957;Kidwell et al 1959). However, it has been reported that good conformation indicates a higher muscle-to-bone ratio (Cuthbertson, Harrington & Smith, 1972;Kauffman et al 1973;Kempster, 1978) and a greater thickness of muscles (Martin, Walters & Whiteman, 1966) at similar carcass weight and fatness.…”

Beef carcass conformation and some relationships with carcass composition and muscle dimensions

1980

View full text Add to dashboard Cite

Carcasses of 129 steers from ten different sire breeds including dairy breeds, traditional British beef breeds and continental breeds were classified according to the shape of the tuber ischii-tuber calcis profiles of their hindquarter using a 7-point conformation scale. Conformation class was found to be related to both commercial and dissected carcass composition as well as the dimensions of seven hindquarter muscles. At the same carcass weight and fatness the muscle content of the hindquarter increased by 0-56 kg and the bone decreased by 0-13 kg linearly per unit increase in conformation class; the corresponding increase in the muscle-to-bone ratio was 0-07. The general trend for muscle dimensions was that the convex carcasses had shorter and thicker muscles than concave carcasses. A simple method of assessing carcass conformation based on three fundamental profiles of the hindquarter, from which the seven conformation classes were derived, permitted the grouping of carcasses according to their composition. Nevertheless the accuracy of the method may be improved with further investigation.

“…On one lot of 141 steers, five live-animal graders estimated the value of the carcasses that the animals would produce from $261 to $1,199 (from 1.1 to 4.9 percent) below the value based on the actual USDA carcass grades [13]. 3 A more precise approach to the task of measuring grading errors is first to determine the magnitude of the errors in absolute units and then to convert these absolute units to monetary values on the basis of price diHerentials between grades at specific times and places.…”

“…At the present time a concerted effort is being made to identify and measure the indicators of the attributes of beef valued by buyers and sellers [1,2,3,9,20]. However, very few data are available on how accurately the grade standards for beef animals can be interpreted.…”

Almost 22 percent of the cash farm income from farming in the United States is derived from the sale of cattle. Much of the market information available to those who buy and sell cattle is based on animals meeting the federal grade standards for live animals. In this paper (a) a method is proposed for measuring the accuracy with which federal grade standards for beef cattle can be interpreted, (b) the accuracy with which seven graders estimated the grades of 497 cattle is reported, and (c) the risk incurred by buyers and sellers of live animals is evaluated. The results suggest that it is possible to save more than $50 million annually by eliminating the risk associated with the trading of live animals.
