Abstract	The objective of this work was to evaluate the effects of replacing soybean meal by urea or starea on feedlot cattle performance. Eighty-one yearling intact males (27 Nellore, 27 Canchim and 27 Holstein) were used, with initial body weight of 250 kg. Animals were assigned to a completely random block design according to initial weight and breed. There were nine pen/treatment with three animals/pen. Experimental treatments were: 1) soybean meal, 2) urea and 3) starea. Diets contained 13% CP and were composed of 80% concentrate and 20% raw sugarcane bagasse. DMI was 6.56, 7.18 and 6.97 kg/day, average daily gain was 0.889, 1.114 and 1.088 kg/day and feed conversion was 7.3, 6.5 and 6.7 kg DM/kg gain for soybean meal, urea and starea, respectively. Soybean meal reduced (P 0.05) between urea and starea treatments.
