Foram conduzidos dois experimentos com o objetivo de avaliar os efeitos da suplementacao enzimatica das racoes a base de milho e farelo de soja sobre o desempenho e metabolizabilidade dos nutrientes em codornas de corte. Os tratamentos foram: controle positivo para atendimento das exigencias; controle positivo suplementado com complexo enzimatico e controles negativos suplementados reduzidos em 2 e 4% nos teores de energia metabolizavel e aminoacidos. Na fase inicial, observou-se aumento no consumo de racao (p < 0,05) no tratamento controle negativo reduzido em 4% na energia metabolizavel eaminoacidos em comparacao aos tratamentos controle positivos. Na fase de crescimento o consumo de racao, conversao alimentar e rendimento de carcaca nao diferiram (p > 0,05). Conclui-se que o complexo enzimatico pode ser utilizado em dietas reduzidas em energia metabolizavel e aminoacidos sem prejudicar o desempenho de codornas de corte. No ensaio de metabolismo, nao foram observadas diferencas (p > 0,05) entre os tratamentos para os coeficientes de metabolizacao das materias seca e organica, proteina bruta e energia bruta. Ocoeficiente de metabolizacao da FDN melhorou (p < 0,05) com a adicao de enzimas.<br><br>Two experiments were carried out to evaluate the effects of enzyme supplementation (xylanase + ƒÀ-glucanase) of diets based on corn and soybean meal on: performance in initial (1-14 days) and growing (15-35 days) phases, and nutrient metabolization of meat-type quails. The treatments were: positive control to meet the nutritional requirements of the specie; positive control supplemented with enzyme complex; and negative controls with two reduced supplementation levels of metabolizable energy and amino acids (by 2% and 4%). In the initial phase, the negative control treatment reduced by 4% of metabolizable energy and amino acids increased feed intake (p < 0.05), compared to positive controls. In the growing phase, there were no differences (p > 0.05) in feed intake, feed conversion ratio and carcass traits. In conclusion, this supplementation can be used successfully in diets with reduced metabolizable energy and amino acid contents for meat-type quails. In the metabolism trial, there were no differences (p > 0.05) in metabolizable coefficients of drymatter, organic matter, crude protein and gross energy among treatments. The metabolization coefficient of NDF improved (p < 0.05) with enzyme supplementation.
