Bone-Muscle Relationships in Beef Carcasses

Texas Agricultural Experiment Station, College Station

Abstract

The relationship of bone to muscle in beef carcasses from 28 yearling Hereford steers, fed for 215 days, with an average weight of 919 lb. at slaughter, was investigated.

Weight, length and weight:length ratios were obtained on the metacarpus, metatarsus, tibia, femur, and radius-ulna. Bone weights and bone weight: length ratios were correlated with weights of sum of loin, rib, round and rump and sum of "retail trimmed" chuck, rib, loin, and "retail trimmed" boneless cushion round and rump, and area of ribeye, which were used as indicators of muscling.

The strong positive correlations obtained indicate that bones of an animal develop proportionately in length and weight and suggest that a real association existed between bone thickness and muscling of the cattle studied.
