The experiments were performed in order to evaluate the use of castor meal autoclaved (FMA) in the diet of Japanese quails. Two experiments were conducted. In the first two hundred and ten were selected for quail production and weight uniformity and distributed in a completely randomized design with five treatments and seven replications of six birds each. Which was rated the best level (0, 7, 14, 21 and 28%) of AMF with calcium oxide in diets of Japanese quail during three cycles of 21 days, to characterize the performance and egg quality. The effects of inclusion levels of AMF were evaluated and significant when the averages were compared and evaluated by Tukey test at 5% probability and later regression analysis to determine the best level. For performance parameters, variables, egg production, egg mass and feed conversion by egg mass showed a linear plateau with the inclusion of FMA by 28%. When checked the quality of eggs, variables, egg weight had an effect linear plateau and specific gravity as a linear effect is increased the FMA in the diets and yolk color presented a cubic effect on the participation of the FMA in the rations. Weight data albumen and yolk decreased linearly and weight of albumen and shell percentage one linear plateau with increase in the amount of FMA rations. Levels of up to 7% are recommended for inclusion in diets of laying quails. For the second experiment were selected by two hundred and sixteen quail production and weight uniformity and distributed in a completely randomized design with six treatments and six replicates of six birds each. We evaluated the inclusion of castor autoclaved bran with calcium hydroxide in the level of 21% (FMA21%) with and without enzymatic complexes (EC) and the CE1 consisting of xylanase, β-glucanase, cellulase, pectinase, protease (acting secondary) and CE2 by xylanase, amylase and protease in diets of Japanese quail during three cycles of 21 days, in order to characterize the performance and egg quality. The effects of inclusion levels of AMF were evaluated using analysis of variance and significant when the means were compared by Tukey test at 5% probability. For the performance parameters of feed intake, egg production, egg mass, feed conversion and egg mass per dozen showed no significant differences. The FMA21% to be included in the diet significantly affected egg weight, presenting results similar to the control by adding the CE1. The color and yolk weight data showed higher when added to the diets CE1 FMA21%, the addition of this level of FMA. The results indicate that the addition of 21% of AMF in diets containing enzyme complex with xylanase, β-glucanase, cellulase, pectinase, protease (acting secondary) provides, in the quail posture, perform as well as when fed diets containing corn and soybean meal.
