ABSTRACT The objective of this study was to evaluate the effect of diets formulated with corn plus soybean meal (CSM) or with 21% autoclaved castor meal (ACM), with the addition of two enzyme complexes (EC1 and EC2), on the performance and egg quality of laying quail. Two hundred and sixteen quails were selected by egg production and weight uniformity and distributed in a completely randomized design with six treatments (in a 2 × 3 cross-factorial arrangement) and six replicates with six birds each. Three CSM and three ACM diets supplemented withEC1, EC2, or unsupplemented were established. The trial lasted three cycles of 21 days. Feed intake, laying rate, egg mass, feed conversion per egg mass, and feed conversion per dozen eggs did not differ. The use of ACM diet reduced egg (EW), yolk (YW), and eggshell (SW) weights, egg specific gravity and increased yolk color. However, EW and YW were similar among quails fed diets containing CSM and ACM when supplemented with CE1.The use of enzyme complex containing xylanase, b-glucanase, and phytase is recommended when 21% autoclaved castor mealis included in the diet of laying quails.
