It was evaluatedthe chemical composition and energy values of slaughterhouse by-product mealfor male Japanese quails (Coturnix coturnix japonica). It was used 320male quails at 32 days of age, distributed in a complete random experimentaldesign, with five diets (one reference diet and four test diets), each one evaluatedwith eight replicates with eight birds per experimental unity. Meals replaced25% of the reference diet and their metabolizable energy values as well as theirmetabolizability coefficients were determined by using the total excreta methodcollection. Values of apparent metabolizable energy (kcal/kg) and apparent energycorrected for nitrogen balance (kcal/kg) are, respectively, 2,152 and 2,142for meat and bone meal; 3,139 and 3,137 for feather meal; 2,658 and 2,651 forfish meal and 3,692 and 3,668 for poultry viscera meal. Metabolizability coefficientsare 60.51% for meat and bone meal; 59.25% for feather meal; 64.09% for fishmeal and 78.64% for poultry viscera meal.
