The experiment was conduced to determine the protein and energy levels, for laying Japanese quails (Coturnix coturnix japonica), in four experimental periods of 28 days each. Six hundred females quails with 45 days of aged and average initial weight of 138.0g were used. The experimental design used was randomized blocks, in 3×5 factorial scheme, with three levels of energy (2,850, 2,950 and 3,050 kcal of ME/kg) and five protein levels (16, 18, 20, 22 and 24% CP), with four replications […]
