Performance of Japanese quails fed diets with low-protein and isoleucine/Niveis de isoleucina em dietas para codornas japonesas
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 supple...

description | 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. Keywords: branched-chain amino acid, performance, nitrogen excretion, egg quality. Com o objetivo de avaliar niveis de isoleucina em ragoes para codornas japonesas em postura, foram utilizadas 648 codornas, distribuidas em delineamento em blocos ao acaso com seis tratamentos e seis repetigoes de 18 aves cada. Os tratamentos consistiram de racao basal com 16% de PB correspondente em nivel de isoleucina de 0,672% e suplementada com isoleucina, em substituicao ao acido glutamico, correspondendo aos niveis de isoleucina de 0,816; 0,960; 1,104; 1,248%. As dietas experimentais foram comparadas a uma dieta controle contendo 20% PB. Foram estudados o desempenho, a qualidade do ovo, os solidos totais dos ovos e nitrogenio nas excretas das aves. Observou-se aumento linear apenas para consumo de isoleucina com elevacao dos niveis de isoleucina das dietas. Pela comparacao das medias de cada combinacao de niveis de isoleucina para dietas com 16% PB com o tratamento controle 20% PB, verificou-se que o consumo de PB, consumo de isoleucina, peso do ovo, excrecao de nitrogenio e cor da gema foram significativamente influenciados. Para codornas japonesas submetidas a dietas com 16% de PB, o nivel de isoleucina de 0,672%, atende as exigencias para obtencao de resultados satisfatorios de desempenho e qualidade de ovos e proporcionou uma reducao na excrecao de nitrogenio. Palavras-chave: aminoacido ramificado |
