【 摘 要 】

- Three trials were conducted to evaluate the effect of enzymatic supplementation of corn and soybean based diets on performance (Trial 1), nutrients digestibility (Trial 2), performance and nutrient flow in the ileal digesta (Trial 3) in broiler chickens. In Trial 1, for experimental diet formulation, the chemical composition of soybean meal (SM) and full fat extruded soybean (ES) were overestimated in 7% for ME and CP, and 5% for Met, Met+Cys and Lys (Treatment C, D, and E) and 9% for ME, 7% for CP and 5% for Met, Met+Cys and Lys (Treatments F, G e H) when there was enzymes addition (Allzyme Vegproâ e Allzyme Lipaseâ). It was concluded that ME, CP and amino acids (Met, Met+Cys and Lys) values can be overestimated in 9, 7 and 5%, respectively, when there was the addition of enzymatic complex to the broilers diets (1-42 days), without reducing bird performance. Treatments used on trials 2 and 3 were: A and B - diets based on soybean meal (SBM) with and without addition of multienzymatic complex (Allzyme Vegproâ) and C and D - diets based on soybean meal (SBM) and full fat extruded soybean (ES) with and without addition of multienzymatic complex (Allzyme Vegproâ). In Trial 2 differences were not observed among treatments for coefficients of apparent metabolization of dry matter, crude protein, gross energy and AMEn. In trial 3, for initial period (1-21 days), growth period (22-42 days) and total period (1-42 days) differences were not observed in feed intake, weight gain and feed: gain among birds fed with diets supplemented with enzymes. In the determination of nutrient flow in ileal digesta, differences among studied treatments were not observed, for 21 and 42 days age.
