Apparent metabolizable energy and apparent metabolizable energy corrected for nitrogen balance of amaranth grains for Japanese quails (Coturnix coturnix japonica)

The objective was to determine the values of apparent metabolizable energy (AME) and corrected for nitrogen balance (AMEn) roasted in natura amaranth grains. A breeding stock 108 female Japanese quails (Coturnix coturnix japonica) with an initial age 29 days used. birds were distributed a completely randomized design three treatments six replications, per experimental unit. used reference diet, diet + 30% amaranth. variables evaluated feed intake, body weight variation, retained nitrogen, crude protein, dry matter digestibility protein. Higher AME AMEn verified grains, relation There no verification regarding influence both natura, protein digestibility. It concluded that grains provided 3888 kcal/ kg 3352 kcal/kg AMEn, while 4044 4028 AMEn.
