      Here we tested how feeding with exogenous enzymes affects the performance, carcass yield, and ileal digestibility in broilers from 21- to 42-days-old. The study included 1008 male broilers randomly distributed into six diets: positive control (PC), corn and soybean meal containing all the nutritional requirements; negative control (NC), with a 120 kcal.kg-1 reduction in metabolizable energy relative to the PC; enzyme complex one (NC + 100 ppm of endo-1,4-beta-xylanase); enzyme complex two (NC + 200 ppm of xylanase, amylase and protease); enzyme blend one (NC + 100 FXU kg-1 of xylanase and 200 FXU kg-1 of amylase); and enzyme blend two (NC + 100 FXU kg-1 of xylanase and 300 FXU kg-1 of amylase). The enzyme complex two (CN + 100 FXU.kg de xilanase e 300 FXU.kg de amilase) and enzyme blend two (NC + 100 FXU kg-1 of xylanase and 300 FXU kg-1 of amylase) had greater weight gain, feed conversion, carcass yield, and digestibility of nutrients than the NC (P < 0,05). We found that enzyme complex two and enzyme blend two valued their nutritional matrix promoting better performance and digestibility of broilers. ; O trabalho foi realizado para avaliar o uso de enzimas sobre o desempenho, rendimento de carcaça e digestibilidade ileal em frangos de corte no período de 21 a 42 dias de idade. Foram utilizados 1008 frangos de corte, machos, distribuídos em seis dietas: controle positivo (CP) a base de milho e farelo de soja, contendo todas as exigências nutricionais, controle negativo (CN) com redução de 120 kcal.kg-1de energia metabolizável, complexo enzimático um (CN + 100 ppm de endo-1,4-beta-xilanase); complexo enzimático dois ( CN + 200 ppm de xilanase, amilase e protease); blend enzimático um (CN + 100 FXU.kg de xilanase e 200 FXU.kg de amilase e blend enzimático dois (CN + 100 FXU.kg de xilanase e 300 FXU.kg de amilase). O complexo enzimático dois (CN + 200 ppm de xilanase, amilase e protease) e blend enzimático dois (CN + 100 FXU.kg de xilanase e 300 FXU.kg de amilase) proporcionaram ganho de peso, conversão ...
