Abstract :The influence of 2 enzyme supplements for diets based on wheat with high or low viscosity on performance and some intestinal parameters of male broiler chickens were investigated. The experiment was of 2 x 3 factorial design, with 2 types of wheat insert ignore into journalissuearticles values(high or low viscosity); and 3 enzyme treatments insert ignore into journalissuearticles values(none, Avizyme 1300-xylanase or Avizyme 1500-amylase);. Ileal digesta viscosity was significantly insert ignore into journalissuearticles values(P < 0.029); higher in birds fed with high viscous wheat than with low viscous wheat. Ileal digesta viscosity insert ignore into journalissuearticles values(P < 0.001); and dry matter content insert ignore into journalissuearticles values(P < 0.002); were significantly reduced by both enzyme preparations. Body weight gain, feed intake, dry matter intake, feed conversion ratio, DM retention and wet or dry excreta output were not significantly insert ignore into journalissuearticles values(P > 0.05); affected by all treatments. There were no significant interactions insert ignore into journalissuearticles values(P > 0.05); between the effects of wheat type and enzyme supplementation. In conclusion, the supplementation of high or low viscous wheat-based diets with the enzyme preparations of amylase or xylanase activity led to significant reductions in ileal digesta viscosity whereas no significant alterations were observed in the performance parameters.
