A biological trial in broilers was conducted with seven treatments: T1- Control (without enzyme); T2 - 500 g/ton NSP hydrolyzing enzyme; T3 -1000 g/ton NSP hydrolyzing enzyme; T4-500 g/ton NSP hydrolyzing enzyme + Phytase, 0.2 per cent DCP reduction; T5-1000 g/ton NSP hydrolyzing enzyme + Phytase, 0.4% DCP reduction; T6- 500 g/ton NSP hydrolyzing enzyme, 2.5% reduction of metabolizable energy, crude protein, lysine and methionine; T7 1000 g/ton NSP hydrolyzing enzyme, 5% reduction of metabolizable energy, crude protein, lysine and methionine. The weight gain (g) recorded in T1, T2, T3, T4, T5, T6 and T7 groups was 1485, 1561, 1600, 1529, 1451, 1417 and 1449 respectively. No significant difference was recorded between the control and enzyme added groups. Significantly (P<0.01) lower feed intake was observed in T6, T2 and T7 compared to T1. The feed efficiency was significantly (P<0.05) better in T2 (1.50) and T3 (1.52) compared to T1 (1.65). A significant or numerical increase in the blood glucose levels was observed in the enzyme supplemented groups compared to the control in before, after 1hr, after 2 hr and after 3hr feeding periods.
