Abstract:
The objective of this experiment was to evaluate the performance of feedlot beef cattle fed diets supplemented with protein concentrate based on cottonseed meal (CSM) urea (UR) or starea (ST), using corn silage as forage. The feedlot period was 80 days. The diets were constituted maintaining the forage:concentrate proportion in the 63:37 level, with nearly 13% CP. No difference was observed in daily weight gain during the experimental period among the CSM, UR or ST treatments (1.14, 1.17, and 1.23 Kg/anim•day) or in the dry matter intakes in % LW (2.63, 2.60, and 2.60), g/kg0.75•day (136.19, 134.74, and 134.81) or kg/anim.•day (9.42, 9.35, and 9.40), respectively. The CP intakes values were 1.28, 1.24, and 1.34 kg of CP/anim.•day and 18.54, 17.86, and 19.24 g/kg.75 •day for the CMS, UR or ST treatments and they did not differ among each other. Values of feed:gain ratios obtained for dry matter were 8.41, 8.01, and 7.67 kg DMI/kg DWG and for the protein:gain ratios, 1.15, 1.06, and 1.09 kg CPI / Kg DWG, respectively, for the CPM, UR and ST treatments, that were similar.
