Uso de sorgo grão inteiro e moído sobre o desempenho, digestibilidade e morfometria das vísceras de perus

Abstract

This paper aimed at evaluating the effects of replacing corn with whole and ground sorghum on the performance, relative carcass weight and viscera, carcass composition and digestibility of nutrients in the diet of turkeys in the initial phase of production (1 to 28 days). Three thousand nine hundred and sixty male turkeys from Nicholas lineage were housed, distributed in a completely randomized design, submitted to the following treatment diets: A) Whole Sorghum (100% Ws); B) ground corn (100% C); C) 75% ground corn + 25% ground sorghum (75%C25%S); D) 50% ground corn + 50% ground sorghum (50%CS); E) 25% ground corn + 75% ground sorghum (25%C/75%S); F) ground sorghum (100% Sg). Each treatment with twelve replicates of 55 birds each. Performance data such as feed intake, body weight, real feed conversion, traditional food conversion and viability did not differ at 28 days of age and the percentages of carcass parts and morphometry of viscera. However, the results of the chemical composition of the carcass were higher for fat in the diet with ground sorghum and better digestibility of crude protein in diets with whole sorghum (100% Si) and ground sorghum (100% Sm) compared corn ground. It was observed that sorghum may be a viable alternative ingredient in the composition of the diets of turkeys. And for performance in creating grain or ground may be provided.
