Description
Summary:The aim of this study was to evaluate the effect of poultry meal on weight gain and carcass yield, under a housing system. 30 Swiss x Zebu steers were used, with an approximate weight of 353 kg, which were assigned under a completely randomized design in three treatments. T1 (control) concentrate without poultry meal; T2 concentrate + 30% poultry meal and T3 concentrate + 35% poultry meal. The composition of the concentrate was based on ground sorghum, maize grain, wheat bran, ground mineral salt bale with 18% crude protein and 70% TDN. A significant effect (p ≤ 0.05) on the percentage of carcass weight of 53.0 was observed; 59.5 and 58.8% for T1, T2 and T3, respectively. The results indicate that supplementation based poultry meal 35% promoted greater yield in feedlot steers.
