Apparent metabolizable energy (AME) and apparent metabolizable energy corrected for nitrogen retention (AMEn) were determined in seven foodstuffs tested in japanese quail feedings. Two hundred and eighty japanese female quails (Coturnix japonica), twenty-six-days-old were used in a completely randomized experimental design, with five replicates and seven quails per experimental unit. The treatments consisted on seven experimental diets and one reference diet. Each experimental diet was constituted, as fed basis, of 70% of the reference diet and 30% of food in test, except for the diet containing soy bean oil without phospholipid, which replaced 10% of the reference diet, as fed basis. The values of AME and AMEn (kcal/kg of fed basis) were: 3.124 and 3.122 (ground corn), 3.152 and 3.102 (spice), 2.980 and 2.947 (broken rice grains), 8.065 and 7.940 (soy bean oil without phospholipids), 2.633 and 2.651 (soybean meal), 2.477 and 2.492 (linseed meal) and 1.323 and 1.274 (peel and pulp of pineapple), respectively.
