Abstract: The objective of this study was to evaluate the influence of an enzymatic association between phytase and xylanase on the production performance of commercial laying hens reared in cage free system during a complete cycle. A total of 840 Hy-Line Brown laying hens were used from 23 to 88 weeks of age and distributed in a completely randomized design, with 4 treatments and 5 replicates of 42 hens each. Hens The dietary treatments were formed according to the enzymatic levels and the nutritional matrix (Conventional: used by Brazilian poultry industries; and overvalued) and were as follows: Positive control: 300 units of phytase (FTU)/kg + 8,000 units of xylanase (BXU)/kg + Conventional Matrix (102 Kcal/kg AME; 0.17% Ca; 0.15% available P; 0.04% Na; 0.02% digestible Lysine); Superdosing (1,500 FTU/kg + 8,000 BXU/kg) + Conventional; Negative control: no enzymes + Overvalued Matrix (120 Kcal/kg AME; 0.22% Ca; 0.20% available P; 0.05% Na; 0.05% digestible Lysine); and Superdosing + Overvalued Matrix. Analyzed variables included productive performance, internal and external egg quality variables. Data were submitted to ANOVA to assess the effect of treatments and analysis of regression to assess the effect of treatments over time. The association of phytase and xylanase increased egg production rate, egg weight, egg mass, feed conversion per egg mass and feed conversion per dozen eggs (P<0.001), regardless of the nutritional matrix valorization. Egg quality was not affected by the enzymatic association. As a conclusion, the association of xylanase and phytase in diets for cage free layers can enhance the production performance, increasing the quantity of albumen and egg weight throughout the whole cycle of production MenosAbstract: The objective of this study was to evaluate the influence of an enzymatic association between phytase and xylanase on the production performance of commercial laying hens reared in cage free system during a complete cycle.
