the objective of this study was to evaluate the performance and carcass traits of steers fed corn or citrus pulp associated with sunflower meal or urea. diets were composed of two energy sources (corn grain and citrus pulp) associated with two protein sources (soybean meal and urea), resulting in four treatments in forage:concentrate ratio of 40:60. it were used 24 steers, ？ angus × ？ nellore (18 months old and 329 kg bw) distributed in a completely randomized design which were finished in feedlot for 80 days. it were evaluated the intake, average daily gain and carcass traits of the animals. intake of dry matter (dmi), crude protein (cpi) and neutral detergent fiber (ndfi) were affected (p<0.05) by diets. the diet with citrus pulp and urea (pu) showed the lowest (p<0.05) dmi (8.30 kg), cpi (1.03 kg) and ndfi (3.31 kg). the average daily weight gain (adg) followed the behavior of dmi, ndfi and cpi and the lowest value (p<0.05) was observed for animals fed diet pu. regarding carcass traits, diets containing corn associated with urea (mu) or sunflower meal (mfg) and citrus pulp associated with sunflower meal (pfg), provided the highest (p<0.05) carcass cold weights (238.37, 247.26 and 237.14 kg, respectively). however, the lowest cold carcass dressing percentage (p<0.05) was obtained in diet mu (50.57%). the association of citrus pulp with urea should not be performed when citrus pulp partially or totally replace corn as energy source in diets, because possibly this association promote an energy deficit resulting in lower performance and worse carcass traits of animals finished in feedlot.
