Abstract
Tenderness of seven muscles of 80 bovine carcasses was measured by sensory evaluation and shear value in relation to age and sex of animals and postslaughter carcass grade. Significant differences in tenderness for individual muscles were found. The psoas major muscle was the most tender and the biceps fermoris the least tender. The meat of young animals was generally more tender than that of the adult ones. However, in the particular muscles, no regular decrease in tenderness with the age of animals was found, and in the psoas major muscle no differences in tenderness were found. In general, sex of animals and quality grade of carcasses did not significantly affect tenderness. Sensory data were correlated significantly (P<01) with shear values (r = −.64) for all animals studied. Copyright © 1975. American Society of Animal Science .
