Digestibilidade de dietas com diferentes fontes de carboidratos e sua influência na glicemia e insulinemia de cães

Abstract

In order to evaluate the influence of the diets with different carbohydrates sources in blood glucose and blood insulin in dogs, were conducted, in Animal Science Department of Federal University of Lavras (UFLA), a experiment with dogs of breed American Foxhound. Were utilized 24 males dogs with average weight of the 34,61 ± 3,42 kg, allotted in randomized blocks design with subdivided piece in time, with four treatments, and one animal per unit experimental. The treatments were three diets formulated to contain the same amount (63%) of the cereals evaluate (corn, sorghum and rice) and a forth diet being a blend in equal parts of each cereal. The animals were fed once per day, for the morning, and the consume established agreed with the prediction equation of the Heusner (1982) for mantence energy, plus 10%. The digestible dry matter, the digestible starch, the digestible energy, the blood glucose and blood insulin were evaluated. For the statistical analysis were utilized the test of Scort-Knott (P<0,05). Thus, the diet 3 (rice) were higher (P<0,05) for the digestibility of dry matter variable and digestible starch variable. For the digestible energy variable, the diets 1 and 3 (corn and rice) were higher then others (P<0,05). It was found that the treatments didn't influence the blood glucose (P=0,51) and blood insulin (P=0,66) for test F. In conclusion, the different sources of the carbohydrates utilized, in the four diets, didn't influence in the blood glucose and blood insulin in health dogs.
