| مستخلص: | The relationships of muscling and finish measurements with carcass yield were studied and compared among three different cattle populations. The correlations between l. dorsiarea and carcass lean were in general low. Calculating l. dorsiarea per 50 kg. of carcass weight increased this relationship in all groups studied.High correlation coefficients between carcass yield measurements and various round measurements support the suggestion that round measurements may be useful in predicting carcass muscling.The importance of fat thickness and fat thickness per 50 kg. of carcass weight for estimating carcass muscling is evident from the high negative relationships between these measurements and measurements of carcass yield.Results of this study indicated that neither separable lean nor retail yield from the wholesale rib was an accurate predictor of carcass muscling. The correlation between percent boneless rib yield and carcass muscling was significant for heifer carcasses, although this same relationship was not significant for steer carcasses. Kidney fat measurements were not highly correlated with carcass muscling.Cattle of similar carcass characteristics exhibited lower correlations than either steer or heifer carcasses selected to differ markedly in fat thickness. Heifer carcasses exhibited anomalously high relationships of boneless rib yield and low relationships of percent kidney fat with carcass yield.Many correlations between the same two variables from two different carcass groups differed widely. These results suggest that it is important to adequately describe the population used when reporting data on beef carcasses. |
