It was used 648Japanese quails with 91.1% of egg production in a completely randomized experimentdesign with nine replicates and eight birds per experimental unit. The dietswere evaluated in a 3 × 3 factorial scheme (food × feed formulation)through bird performance measures and egg quality. The interaction among alternativefood and formulation influenced feed intake. Both performance and internal andexternal egg traits were not affected by food alternative. Weight gain, layingrate, egg average weight, egg mass, feed conversion per mass and shell percentagevaried according to the formulation. Values of corrected apparent metabolizableenergy of corn, sorghum, soybean meal and poultry by product meal, meat andfish bones determined in broilers and laying hens are not suitable for formulationof diets for Japanese quails.
