Treatments consisted of a basal level corresponding to 0.672% isoleucine and supplemented with isoleucine to the levels of 0.816, 0.960; 1.104; 1.248%. The experimental diets were compared to a control diet containing 20% CP. The parameters studied were: performance, egg quality, total solids and nitrogen in the excreta. There was a linear increase only for isoleucine intake with increasing levels of isoleucine in the diets. The comparison of mean values of each combination of isoleucine levels for diets with 16% CP with the control with 20% CP showed that the intake of CP and isoleucine, egg weight, nitrogen excretion and yolk color were significantly affected. For Japanese quail fed diets with 16% CP, with isoleucine level at 0.672%, meets the requirements for obtaining satisfactory performance and egg quality and promoted a reduction in nitrogen excretion. 2016 artículo científico 1806-2636 https://www.redalyc.org/articulo.oa?id=303159348015 https://www.redalyc.org/journal/3031/303159348015/ https://www.redalyc.org/journal/3031/303159348015/html/ https://www.redalyc.org/journal/3031/303159348015/303159348015.epub https://www.redalyc.org/journal/3031/303159348015/movil 10.4025/actascianimsci.v38i2.29533 en http://www.redalyc.org/revista.oa?id=3031 Acta Scientiarum.
