Glicose de milho em dietas para frangos de corte de 1 a 7 dias de idade

Abstract

The objective of this study was to determine the values of apparent metabolizable energy (AME) and apparent corrected by nitrogen balance (AME) and the coefficient of apparent metabolizable crude energy (CMAEB) of the corn glucose for broilers from 1 to 7 days of age using four levels of substitution of the reference diet by the ingredient tested. Was conducted a metabolism trial, using 360 male broiler chicks of the lineage Cobb500 1-7 days old, allocated in metabolic cages in a completely randomized design with five treatments and six replicates of 12 birds. The treatments consisted of a basal diet and four test diets with different levels of basal diet by replacing corn glucose (5, 10, 15 and 20%). Glucose corn used was produced by Corn Products Brazil and in its composition contained 81.39% dry matter and 3824 kcal / kg gross energy.Was used method of total excreta collection. The data were subjected to analysis of variance and regression at 5% probability. The corn glucose showed the highest energy when it was used 20% of the diet by replacing glucose, with 3550 kcal / kg DM, 3648 kcal / kg DM and 95.38% for AME, AME n and CMAEB respectively. Recommended the level of substitution of 20% glucose for the determination of their energy values for broilers 1 to 7 days.
