Beef carcass composition of slaughter cattle differing in frame size, muscle score, and external fatness
Article Abstract:
The effect of carcass traits such as sex class, frame size, muscle score and external fatness on the percentage yield of boneless subprimals at three external fatness endpoints was evaluated. Twelfth-rib fat thickness and sex class were found to have the greatest effect on the yield of boneless subprimals and the production of trimmable fat. As muscle score changed from thick to thin, yield of round and rib decreased while loin and plate yield increased. The percentage of trimmable fat increased slightly as frame size decreased, but frame size was generally not an important determinant of yield.

Evaluation of the Hennessy grading probe to predict yields of lamb carcassesfabricated to multiple end points
Article Abstract:
From a total of 278 lamb carcasses selected, measured for fat thickness with the Hennessy grading probe at the 12th intercostal space, 3.8 cm from the backbone and remeasured after a 24 hourchilling period then graded by a USDA grader, 165 were fabricated into wholesale cuts (0.64 cm of external fat trimmed) and 113 into tray-ready retailcuts (0.25 cm trimmed). Carcass weight, fat thickness, adjusted fat thickness, hot and chilled carcass fat measures, kidney and pelvic fat percentage, and USDA yield grade were found to affect cutting yield.

Retail cut yields of Rambouillet wether lambs fed the beta-adrenergic agonist L(sub 644,969)
Article Abstract:
Rambouillet wether lambs were given a diet supplemented with beta-adrenergic agonist (BAA), L644,969. The effect of the supplement was evaluated after slaughtering the lambs upon reaching the desired weight of 54.5 kg. Results showed that the supplemented diet increased longissimus muscle area and depth, as well as the leg and carcass conformation scores, but decreased the yield grade and the flank lean color score. Although BAA increased yields of boneless and trimmed cuts, it did not significantly enhance yields of boned cuts.
