This experiment was carried out at State University of Maringá, Brazil. Forty eight crossbred bulls with 318 kg and 22 months old were used in the experiment, and remained in feedlot for 94 days. The diets were composed of 50% concentrate and 50% roughage. The treatments were completely randomized consisting of four treatments with different additives. It was determined that the final weight, hot carcass weight, carcass dressing, average daily gain, intake of dry matter, intake of dry matter in relation to body weight, crude protein intake, intake of organic matter, mineral matter intake and intake of fiber in neutral detergent. Means were compared by Tukey test at 5% significance using the SAS. The final weight was higher (P<0.01) to Confimax (485.5 kg) than in the group Funcional Oils (456.9 Kg), the group Control (464.3) and Yeast (469.1) were similar than the other groups, the hot carcass weight was higher (P<0.01) to bulls fed with Confimax (254.6 Kg) in relation with bulls fed with Funcional Oils (238.95 Kg). The average daily gain was higher (P<0.01) to Confimax (1.76 kg) than others groups, the group control with 1.54 Kg, Functional Oils with 1.53 Kg and the Yeast group with 1.59Kg
