Notes:
Longissimus (LD) muscle samples/steaks were obtained from 32 intact and 32 castrate male crossbred beef animals slaughtered at 8-, 12-, 16-, and 20-months of age. Most of the LD biophysical traits evaluated were significantly affected by age and sex condition. Marbling and texture estimates favored the steers but no sex differences were observed for color and firmness estimates. Objective color, firmness and tenderness measurements generally favored the steers although bullocks showed higher expressible juice values. Steer muscle had a greater cooking rate and less cooking loss than that of bullocks. Little sex differences in cooking time were noted. Age effects on biophysical attributes were most pronounced at 12 and/or 16 months of age. There appears to be little or no improvement in the important biophysical properties of beef longissimus muscle obtained from intact males or from animals older than 16 months.
