IDENTIFICATIONS OF CARCASS CHARACTERISTIC FOR ESTIMATING THE COMPOSITION OF BEEF CARCASS

Factors Affecting Carcass Composition and Beef Quality

The Genetic Improvement of Carcass Composition in Beef Cattle

Although carcass trait selection programs have primarily focused on carcass marbling (quality grade), recent changes in the North American beef industry will very likely increase the economic importance of carcass composition (yield grade). Ultrasound technology is a valuable tool in these efforts. This review summarizes recent research pertaining to the role of ultrasound in improving carcass ...

Leptin as a predictor of carcass composition in beef cattle.

Our objective was to determine if serum concentrations of leptin could be used to predict carcass composition and merit in feedlot finished cattle. Two different groups of crossbred Bos taurus steers and heifers were managed under feedlot conditions near Miles City, MT. The first group consisted of 88 1/2 Red Angus, 1/4 Charolais, and 1/4 Tarentaise composite gene combination steers (CGC) harve...

Predicting beef carcass cutability.

Analyses were conducted to develop and test the efficacy of beef carcass cutability prediction equations. Data from 1,602 calf-fed steer carcasses (Germplasm Utilization Project; GPU) were used to develop the equations and an additional 1,160 calf-fed steer carcasses (Germplasm Evaluation Project; GPE) were used to validate the equations. In both experimental groups, USDA yield grade ranged fro...

Beef Carcass Appraisal

Carcass assessment in Australia, and probably in most beef producing countries of the world, has been, and still is, in the hands of a relatively few specialists actively engaged in the meat industry. These specialists from long experience determine reasonably quickly and accurately by eye the desirable and undesirable features of a carcass. In competitions a point score system has been applied...
