This study was carried out to assess how the addition of enzymes to broiler diets composed of soya bean and maize impacts their performance. A total of 144 day-old Vencobb broiler chicks were divided into eight groups consisting of nine birds each, with two replicates. Experimental diets were formulated based on the NRC (1994) guidelines. Multi-enzyme supplements containing cellulase (400 units/g), xylanase (2000 units/g), pectinase (600 units/g), and protease (2000 units/g) were prepared and added to the feed at a rate of 500 g/ton. The experimental period was 42 days. Live weight gain and feed consumption were determined at weekly intervals. The enzyme supplementation did not show significant variation in mean body weight gain among treatment groups at 3rd and 6th week of age even with the reduction in energy and protein intake. The feed intake was significantly lowest (P < 0.01) in T7 at 3rd week of age, whereas, significantly lowest (P < 0.01) feed intake was recorded in T3 and T7 at 6th week of age. Significantly lowest FCR was observed in T2 and T4 at 3rd (P< 0.05) and 6th week of age (P< 0.01). A net profit of Rs. 4.94 (T4) and 3.97 (T3) per bird was obtained by reducing the energy level by 5 to 10 per cent. It can be concluded that the addition of enzymes to diets based on soya bean and maize improves the performance of broilers with low protein and energy, thus improving the revenue of the farm.
