A study was conducted to evaluate the effect of supplementation of xylanase enzyme on nutrient utilization of broiler chicken fed de-oiled rice bran based ration. One hundred and sixty unsexed day-old broiler chicks belonging to a single hatch, were purchased, weighed and randomly allotted in to five experimental groups, comprising two replicates of sixteen chicks each. The experimental diets were Tc- Control (3% CF without xylanase), T1 - 3% CF with xylanase, T2 - 3.5% CF with xylanase, T3 - 4% CF with xylanase and T4 - 4.5% CF with xylanase. Xylanase supplemented at the rate of 10g/100 kg feed. Dry matter and ether extract digestibility was similar in all treatment groups. The apparent digestibility of crude fiber was significantly (P<0.05) higher in treatment group than that of control. The apparent digestibility of crude protein was significantly (P<0.05) higher only in T1(3% CF with xylanase) group compared to control. Apparent metabolizable energy (AME) value of the treatment diet was significantly (P<0.05) lower, when compared to unsupplemented low fiber diet. It was concluded that supplementation of xylanase enzyme to de-oiled rice bran based diet increases digestibility of crude fiber and crude protein, hence can be included in broiler diet to improve performance.
