Resumo: This study was conducted to evaluate the effect of the supplementation of enzymatic complexes on the performance and carcass characteristics of broiler chickens from both sexes. Five diets were evaluated: positive control diet based on corn and soybean meal with meat and bone meal without enzyme; negative control diet formulated with 3% less of metabolizable energy; negative control + 0.05% of complex A (600 U/g of xylanase, 8000 U/g of amylase and 800 U/g of protease); negative control + 0.04% of complex B (200 kNU/g of α-amylase and 350 FBG/g of β-glucanase); and negative control + 0.04% of complex B + 0.01% of enzyme C (1000 FXU/g of xylanase). No significant differences were found in the performance of birds from 1 to 7 days of age. From 1 to 21 days of life, males consumed more ration than females. Diets four and five resulted into better weight gains only for males. The best results of feed conversion were obtained with the use of the enzymatic complexes. In the total period, males and females that received the positive control consumed less ration than the other diets. Diet four provided the best weight gain result for males. In relation to feed conversion, males presented the best conversion rate from the use of enzymatic complexes. Females that received diet one and diet five presented better feed conversion rates. No significant differences were observed for the effect of diets on the carcass, breast and abdominal fat yields. It could be concluded that the use of the enzymatic complexes was effective in recovering the performance of birds but decreasing 3% of the metabolizable energy.
