Abstract

An experiment was conducted to study the effect of P-glucanase alone and in combination with xylanase on energy value, nutrient utilization and intestinal viscosity in broiler chickens fed with diets based on barley of low or high viscosity. Barley samples were selected out of ten samples collectedfrom different regions in Slovenia, according to the most different extract viscosity. A total of 38 twenty-one-day old, individually caged, male broiler chicks were used in balance experiments. The animals received one of the barley based diets prepared with one of the two barley samples. Both diets remained unsupplemented or were either supplemented with beta -glucanasealone (160 beta GU/kg) or with beta -glucanase and xylanase (160 beta CU/kg + 2800 XU/kg). The results of the experiment confirmed the improvement innutrient utilization (dry matter; nitrogen), in terms of an increase in the energy value of the feed and in a reduction of intestinal viscosity, resulting from the addition of enzymes. However, the results also clearly showed differences between the two bar ley samples based diets in their responseto different enzyme treatments, where only diets: based on high extract viscosity barley showed significant results. Furthermore, the results clearlyindicated that in order to achieve significant improvement in the dry matter, nitrogen and energy utilization of barley based diets, the addition of beta -glucanase alone was not always sufficient. As a consequence, the combination of both beta -glucanase and xylanase may be advised.
