Resumos

O presente estudo foi conduzido com o objetivo de avaliar a influência da ingestão de diferentes fontes de amido sobre indicadores metabólicos e enzimáticos em sangue e fígado de jundiás. O experimento foi realizado durante 20 dias, em sistema de recirculação de água. Foram utilizados 60 peixes (peso médio inicial de 60±4g), divididos em três tratamentos, compostos por dietas com inclusão de aveia descascada; farelo de arroz desengordurado e uma dieta controle, todas com 37% PB e 3200 Kcal ED/Kg. Não houve diferença significativa para os parâmetros de crescimento. As análises hepáticas demonstraram redução no teor de glicogênio para o tratamento que continha aveia; no entanto, sem alterações aparentes na atividade das enzimas alanina-aminotransferase e glicose-6-fosfatase. Quanto às análises sanguíneas, não foram observadas diferenças significativas nas determinações de colesterol total, colesterol HDL e albumina, porém, os níveis séricos de proteínas totais foram maiores para o tratamento com farelo de arroz desengordurado e os níveis de triglicerídeos foram menores nos animais que receberam dieta contendo aveia como fonte amídica. Pode-se concluir que o jundiá é capaz de metabolizar diferentes fontes de carboidrato, sem a necessidade de utilizar a proteína, tanto da dieta quanto a corporal, como fonte de energia.

This study was conducted to evaluate the influence of ingestion of different sources of starch on enzymatic and metabolic indicators in blood and liver of Rhamdia quelen. The experiment was conducted during 20 days in water recirculation system. Sixty fishes (initial average weight 60g) were used and divided into three treatments composed of the following diets: inclusion of peeled oats, defatted rice bran and control diet, all with 36% crude protein and 3,200 Kcal DE/Kg. There was no significant difference in growth parameters. The analysis demonstrated a reduction in liver glycogen content for the treatment with oats; however, no apparent changes in the activity of the enzymes alanine-aminotransferase and glucose-6-phosphatase were observed, raising the possibility that the fishes did not use gluconeogenesis. The blood analysis, showed no significant differences in the determinations of total cholesterol, HDL cholesterol and albumin; however, serum levels of total protein were higher for treatment with defatted rice bran, and triglyceride levels were lower in animals that received diet containing oat as starch source. It can be concluded that Rhamdia quelen is able to metabolize various sources of carbohydrate, without the need to use either diet or body protein as an energy source.
