Efeito da suplementação enzimática em rações com farelo de soja e soja integral extrusada sobre a digestibilidade de nutrientes, o fluxo de nutrientes na digesta ileal e o desempenho de frangos

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