Relationships of Measurements of Live Animals to Weights of Wholesale Cuts of Beef¹

University of Maryland

Abstract

Multiple correlations were used to study the predictability of the weights of wholesale cuts of carcasses by use of bodily measurements taken on 50 beef type steers prior to slaughter. The steers ranged in weight from 800 to 1,445 pounds (ave. 1118 pounds) and graded from choice to medium (mostly good and choice). Multiple correlation values secured for the various cuts were cross-cut, 0.99; rib, 0.97; rough loin, 0.98; trimmed loin, 0.97; short loin, 0.93; sirloin butt, 0.96;and round, 0.93. The size of the multiple correlations secured by various combinations of measurements for each cut was also studied. The practicability of securing measurements and the possible use of measurements as a possible objective method for assisting in the selection of breeding animals were discussed.
