The effect of protein and energy levels on 42nd day carcass yield of European quails (Coturnix coturnix coturnix) was evaluated. A completely randomized design with five replicates and eight quails per experimental unit was used. The treatment consist on diets with two energy metabolic levels (2900 and 3100kcal EM/kg) and four protein levels (22, 24, 26 and 28% of crude protein). The traits analyzed were body weight and weight and yield of carcass, tight, breast, fat and edible viscera. No significant effects of crude protein and metabolic energy levels on carcass traits were found.
