Three experiments were carried on the animal science Department of the Federal University of Viçosa. The first one to determined chemical composition, metabolizable energy values and gross energy metabolizability coefficient of eleven feedstuff for male japanese quails; the second experiment determined ileal digestibility coefficients and digestible amino acids values of seven feedstuff for male Japanese quails; the third experiment compared the performance japanese quail feed diets based on nitrogen corrected metabolizable energy of corn, sorghum, soybean meal, poultry by-product meal, meat an bone meal and fish meal, for broilers and Japanese quails. Total excretion collection method was used to determine values for apparent metabolizable energy (AME), nitrogen corrected apparent metabolizable energy (AMEn), gross energy apparent metabolizability coefficient (EMC) and gross energy nitrogen corrected apparent metabolizability coefficient (EMCn) for 32-d-old male Japanese quails. A completely randomized experimental design with eleven treatments, eight replicates and eight quails per experimental unit was used in the first experimental. The feedstuff studied were: corn, sorghum, soybean meal, extruded whole soybean, micronized whole soybean, canola meal, corn gluten meal, meat and bone meal, feather meal, fish meal and poultry by-product meal. The AME and AMEn (Kcal/Kg) values as fed were: corn 3.261 and 3.252, sorghum 3.219 and 3.211, soybean meal 2.287 and 2.276, extrused whole soybean 3.481 and 3.479, micronized whole soybean 4.029 and 4.018, canola meal 1.894 and 1.888, corn gluten meal 3.731 and 3.712, meat and bone meal 2.152 and 2.142, feather meal 3.139 and 3.137, fish meal 2.658 and 2.651 and poultry by-product meal 3.565 and 3.545, respectivaly and the EMC (%) and EMCn (%) of feedstuffs were: corn 84,51 and 84,30, sorghum 80,85 and 80,66, soybean meal 55,01 and 54,74, extrused whole soybean 67,45 e 67,42, micronized whole soybean 73,29 and 73,09, canola meal 45,29 and 45,12, corn gluten meal 69,96 and 69,61, meat and bone meal 60,82 and 60,51, feather meal 59,29 and 59,25, fish meal 64,26 and 64,09 and poultry by-product meal 79,08 e 78,64, respectively. In the third experiment, a total of 720 quails with 91,1% of egg production and 19week-old were used in a completely randomized experiment design with eight replicates and eight quails per experiment unit. The treatments consisted in a 3x3 factorial arrangement (feed formulation x feedstuff). The variable studied were body weight, viability, egg production, feed conversion, specific weight, and absolute and relative weight of egg components. The results suggest nitrogen corrected apparent metabolizable energy values of corn, sorghum, soybean meal, poultry by-product meal, meat and bone meal and fish meal for broilers are not adequate for japanese quails diet formulation.
