|[en] Three experiments were conducted to investigate the mode of action of 5 hemicellulases supplemented to wheat-based broiler diets. Performances parameters and digesta viscosity were measured during growth period. Total collection of excreta was carried out for determination of AMEn content of the diets and of apparent crude fat, Kjeldahl-nitrogen and crude cellulose digestibilities. Addition of xylanase improve daily body gain by 1 to 6% and feed conversion ration by 1,5 to 4%, as the apparent nutrient digestibility and the content of AMEn in the diets supplemented with enzymes. Although viscosity values seemed not correled to improved performances, Grindazym G shows an increase in the digesta viscosity for all the period of measurement. It can be concluded that the beneficial action of xylanases is more due to the improved release of the nutrients entrapped by the NSP, following degradation of these structures, than to the generally accepted decrease in digesta viscosity.|
