Abstrakt: The objective of this research was to evaluate the effect of the inclusion of an enzyme complex (carbohydrases, proteases and phytase) in diets formulated with DDGS inclusion levels (0 to 30%) in parameters of performance, nutrient digestibility and serum biochemical profile of broiler chickens from 1 to 42 days old. The inclusion of DDGS impaired the performance characteristics in all phases, but broilers feeding with diets containing up to 8% DDGS improves the percentage carcass. Addition of the enzyme complex improved feed conversion by 3.6% and percentage of breast by 1.6%. At 42 days of age, there was a linear decreasing effect of the addition of DDGS in the diets on the relative weight of PV + gizzard (proventriculum + gizzard). Diets without enzyme addition decreased IDCDM, IDCCP and IDCNDF. Inclusion of DDGS up to 8 % results in maximum percentage carcass. The use of exogenous enzymes improves FCR (feed conversion ratio) in the pre-initial phase.
