Effect of Supplementation of Fiber Degrading Enzymes on Performance of Broiler Chickens Fed Diets Containing De-Oiled Rice Bran

P. Anuradha and Barun Roy

Abstract:
The aim of this trial was to examine the possibilities of effective utilization of de-oiled rice bran by supplementing xylanase enzyme in broiler ration and thereby the performance of broiler chickens. One hundred and sixty unsexed day-old broiler chicks (vencobb) belonging to a single hatch, were purchased from a commercial hatchery, wing banded, weighed and randomly allotted into 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 10 g/100 kg feed. De-oiled rice bran was used as a source of crude fibre. Body weight gain and feed consumption was significantly (p<0.05) higher in treatment group, when compared to control group. Mortality rate was significantly (p<0.05) lower in enzyme supplemented high fiber group, when compared to control group. There was no significant (p>0.05) variation among the treatment and control group in terms of Feed Conversion Ratio (FCR), Protein Efficiency Ratio (PER), Dressing percentage, Eviscerated weight and Abdominal fat pad (percentage). However, breast muscle, thigh muscle and giblet weight (percentage) was significantly (p<0.05) higher in enzyme supplemented high fiber diet fed group, when compared to control group. Among the treatment groups, net profit Rs/kg body weight gain was highest in T4 (4.5% CF with xylanase) group. It was concluded that maintaining the maximum fiber level along with incorporation of xylanase as fiber degradable enzyme in feed may have better cost benefit ratio than that of low fiber diet without xylanase.
