Non-carcass components of cattle finished in feedlot with high grain diet

The objective of this study was to quantify the non-carcass components of steers and heifers finished in feedlot and fed with high grain diets. Altogether, 45 Charolais and Nellore crossbred cattle of two categories, 21 heifers with an initial age of 32 months and 24 steers with an initial age of 20 months, were used.
