The effect of partial replacement of maize by orange pomace supplemented with enzymes xylanase and cellulase in broilers was studied. One hundred day-old broiler chicks were distributed into five groups. Group T0 served as control and received conventional diet. In groups T1, T2, T3 and T4, 15% maize of conventional diet was replaced by orange pomace. In addition, groups T2, T3 and T4 received supplementation with enzymes; xylanase (5g/100kg), cellulase (5g/100kg) and xylanase & cellulase (2.5g each/100kg), respectively. The broilers fed enzyme supplemented diet had higher average live weight as compared to the control group. No significant differences in body weight gains were noticed among all treatments. Feed consumption was more in the treatment groups than the control group, which may be due to higher crude fibre content in the treatment diets due to replacement by orange pomace. However, differences among the groups were non-significant. Enzyme supplementation had no significant influence on feed efficiency during the overall growth phase. Feed price and feed cost per kg of live weight was reduced in treated groups as compared to control. It was concluded that supplementation of combination of xylanase and cellulase enzymes in the orange pomace treated group resulted in numerically higher gain in weight in broilers.
