          Abstract

          Esta pesquisa foi conduzida com o objetivo de verificar o melhor nível de torta de dendê na dieta de cordeiros por meio da avaliação da condição hepática. Foram utilizados 32 cordeiros Santa Inês não-castrados distribuídos em quatro dietas com 0,0; 6,5; 13,0 e 19,5% de torta de dendê na matéria seca (MS). A cada 15 dias, foram coletadas amostras de sangue dos animais, totalizando cinco coletas em todo o período experimental. Foram determinados os teores de triglicérides, colesterol, proteínas totais, albumina e globulina; as atividades das enzimas alanina aminotransferase (ALT), aspartatoaminotransferase (AST) e gama glutamiltransferase (GGT); e as concentrações séricas de bilirrubina total, direta e indireta. O aumento do percentual de torta de dendê na dieta não influenciou a concentração de triglicérides, cujo valor médio foi de 40,57 mg/dL, mas elevou as concentrações de colesterol. Também não ocasionou diferença no conteúdo de proteínas totais, mas teve efeito quadrático crescente nos níveis de albumina e ureia e efeito linear decrescente nos níveis de globulinas. Não foram observadas diferenças estatísticas nas atividades das enzimas alanina-aminotransferase, aspartato-aminotransferase e gama-glutamiltransferase, que foram de 6,40; 37,59 e 62,38 UI/L, respectivamente. Igualmente, não foi detectada influência sobre a bilirrubina total, direta e indireta, cujas médias foram de 0,50; 0,11; e 0,38 mg/dL, respectivamente. O uso de torta de dendê em níveis de até 19,5% da dieta não causa transtornos metabólicos hepáticos em cordeiros.

          This study was conducted in order to verify the best level of palm kernel cake in the diet for lambs through evaluation of hepatic condition. It was used 32 non-castrated Santa Inês lambs distributed into four diets with palm kernel cake levels of 0.0; 6.5; 13.0 and 19.5% in the dry matter (DM). Every 15 days, blood samples were collected, totalizing five collects for the whole experimental period. It was determined levels of triglycerides, cholesterol, total protein, albumin and globulin, activities of alanine aminotransferase, aspartate-aminotrasferase, and gama-glutamiltransferase enzymes, and serum concentrations of total, direct and indirect bilirrubine. The increase of palm kernel cake percentage in the diet did not affect concentration of triglycerides whose mean value was 40.57 mg/dL. However, cholesterol levels increased as the palm kernel cake was increased in the diets. There was no difference in the total proteins either, but there was an increasing quadratic effect in the levels of albumine and urea and a decreasing linear effect in the levels of globuline. Statistical differences were not observed for activities of alanine aminotransferase, aspartate-aminotrasferase, and gamaglutamiltransferase enzymes, which showed mean values of 6.40; 37.59 and 62.38 UI/L respectively. Similarly, it was not detected influence on the total, direct, and indirect bilirrubine, whose mean values were 0.50; 0.11; and 0.38 mg/dL, respectively. The use of palm kernel cake at levels up to 19.5% does not cause metabolic disorders in lambs.
