- Performance of Japanese quails fed diets with low-protein and isoleucine Graciene Conceição dos Santos Edivaldo Antônio Garcia Javer Alves Vieira Andréa de Britto Molino Kleber Pelicia Daniella Aparecida Berto Agrociencias branched performance egg quality chain amino acid nitrogen excretion Aiming to assess isoleucine levels in low protein diets for laying Japanese quails, 648 quails of 182 days of age were distributed in experimental block design with six treatments and six replicates of 18 birds each. 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.
