Resumo: The 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.

Foram utilizados 32 cordeiros machos não castrados com aproximadamente 60 dias de idade e 15 ± 0,2 kg, alojados em baias individuais e abatidos aos 32,0 ± 0,2 kg de peso corporal. Os tratamentos foram compostos por quatro rações: C- cana-de-açúcar + concentrado; CG- cana-de-açúcar + concentrado com grãos de girassol; CE- cana-de-açúcar + concentrado com 1000 mg vitamina E kg-1 de matéria seca (MS) da ração e CGE- cana-de-açúcar + concentrado com grãos de girassol e 1000 mg vitamina E kg-1 de MS da ração. O delineamento experimental foi o inteiramente casualizado em esquema fatorial 2 x 2 (com ou sem grãos de girassol e com ou sem vitamina E na base da MS da ração) e as médias comparadas pelo teste de Tukey a 5% de significância. O consumo de vitamina E pelos cordeiros melhorou o ganho médio diário de peso (0,241 kg). A inclusão dos grãos de girassol proporcionou (P < 0,05) maior consumo de extrato etéreo (20,91 g dia-1) e consequentemente maior (P < 0,05) digestibilidade desse nutriente (85,34%), no entanto reduziu (P < 0,05) os consumos de carboidratos totais (394,81 g dia-1) e não fibrosos (242,47 g dia-1) como consequência direta da composição da ração. A inclusão de grão de girassol e vitamina E na dieta dos cordeiros não influenciou (P > 0,05) nas medidas morfológicas e quantitativas da carcaça. Grãos de girassol e vitamina E mostraram-se fontes alternativas satisfatórias para inclusão no concentrado para cordeiros confinados, proporcionando bom desempenho e carcaças com boa qualidade.UEL2016-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2154910.5433/1679-0359.2016v37n4p2133Semina: Ciências Agrárias; Vol. 37 No. 4 (2016); 2133-2144Semina: Ciências Agrárias; v. 37 n. 4 (2016); 2133-21441679-03591676-546Xreponame:Semina.
