Study on Probiotic Effect of Xylanase Supplementation in Broiler Feed

摘要

The present experiment was conducted to study the effect of xylanase enzyme supplementation on body parameters of broiler birds. The experimental birds were distributed into five equal groups including control. Studies on body weight gain revealed that at the end of 4th week of experiment, significant difference in body weight gain among the birds of the control and various treatment group was noticed (P<0.05) though there was subtle difference among the birds of control and various treatment groups(T_1-T_4). Birds of T_3 group revealed the highest body weight gain followed by the birds of T_1 T_2 and T_4 groups respectively. Birds of the control group revealed the lowest body weight gain. At the end of 5th and 6th week of experiment there was significant difference (P<0.05) in the body weight gain among the birds of the control and various treatment group. Birds of T_3 group revealed the highest body weight gain and the lowest body weight gain were observed in the birds of control group.
