Abstract

The aim of this work was the replacement evaluation of corn by dry by-product of cassava starch extraction on carcass traits of crossbreed heifers in feedlot. Thirty crossbred heifers aged 21 months were used. In pre-experimental period (49 days) the heifers were fed with soybean meal and corn concentrate (19.67% CP). In the experimental period (57 days) 15 heifers were fed with the previous diet and the other 15 were fed with by-product of cassava and sorghum silage. Subcutaneous fat was thicker (P < 0.05) in the carcasses of the heifers fed with corn than the ones fed with dry cassava by-products (3.34 vs 2.37 mm). However, the thigh thickness (26.97 vs 26.00 cm), Longissimus dorsi area (70.91 vs 63.17 cm2) and the muscle percentage (69.83 vs 66.29%) were highen (p < 0.05) for the heifers that consumed the diet with dry cassava by-products than the others with corn diet. The replacement of corn by dry cassava by-products influenced carcass traits
