To determine the nutritional value of corn, millet and sorghum in different sizes for broiler chickens, Label Rouge, animal performance and development of the digestive organs, experiments were performed in the areas of Poultry, Federal University of Goiás (UFG) and the Federal University of Tocantins (UFT). We evaluated the values of apparent metabolizable energy (AME) and apparent metabolizable energy corrected for nitrogen balance (AME) in the dry and natural, the coefficients metabolism of nutrients, animal performance up to 28 days and the biometrics of the digestive organs of broiler type rustic Red Label line with diets based on corn, millet and sorghum in different sizes For the determination of AME and AME of grains, we used the method of excreta collection of chickens 14 days old were distributed in a completely randomized in two experimental trials, using 60% reference diet and 40% of food test. The AME values of dry matter of coarsely ground corn, finely ground corn, millet grain, finely ground millet, sorghum grain, sorghum grain sorghum thick and finely ground, were 3530, 3445, 3617, 3586, 3295, 3156 and 3024 kcal / kg, respectively and the values of the AME 3273, 3200, 3352, 3372, 3137, 3147 and 2.967kcal/kg natural matter...
