dc.description.abstractThe aim of this study was to evaluate performance, nutrient digestibility, and carcass quantitative traits of lambs fed diets with and without sunflower seeds and Vitamin E. Thirty-two uncastrated lambs at approximately 60 days of age, with 15 ± 0.2 kg, were housed in individual stalls and slaughtered at 32.0 ± 0.2 kg body weight. Treatments consisted of the following four diets: C = sugarcane + concentrate; CS = sugarcane + concentrate with sunflower seeds; CE = sugarcane + concentrate with 1,000 mg Vitamin E kg-1 diet dry matter (DM); and CSE = sugarcane + concentrate with sunflower seeds and 1,000 mg Vitamin E kg-1 diet DM. The experimental design was completely randomized, in a 2 × 2 factorial arrangement (with and without sunflower seeds and with or without Vitamin E, on the diet DM basis), and means were compared by Tukey's test at 5% significance level. Consumption of Vitamin E intake by the lambs provided (P<0.05) the highest ether extract intake (20.91 g day-1) and consequently the highest (P<0.05) digestibility of this nutrient (85.34%); however, it reduced (P<0.05) the intakes of total carbohydrates (394.81 g day-1) and non-fibrous carbohydrates (242.47 g day-1) as a direct consequence of the diet composition. Inclusion of sunflower seeds and Vitamin E in the lamb diets did not influence (P>0.05) carcass morphological or quantitative measurements. Sunflower seeds and Vitamin E showed to be satisfactory alternatives for inclusion in the concentrate for feedlot lambs, providing good performance and quality carcasses.en
