Mean values with different superscripts in the same row (different dietary treatments on the same day of storage) were significantly different (P < 0.05).
SEM, Standard error of mean; B, fixed effect of beef type; GSE, fixed effect of added grape seed extract.
GSE dose: GSE‐0, no added GSE; GSE‐250, 250 mg GSE/kg meat.
Beef from animals fed different diets: C, conventional diet; OME3, omega‐3 polyunsaturated fatty acids (PUFA) supplemented diet; CLA, conjugated linoleic acid supplemented diet; OME3 + CLA, omega‐3 PUFA plus CLA supplemented diet.
