Abstract:
A biological trial in broilers (180 chicks) was conducted for a period of 42 days with six treatments 30 birds each. T₁ as control, T_2: control + 250 g /ton NSP enzyme, T₃: control + 500 g/ton NSP enzyme, T_4:1000 g /ton NSP enzyme, T_5: control + phytase enzyme 300 IU/kg of feed with reduction (14.6%) in available phosphorus, T₆: control + phytase enzyme 600 IU/kg of feed with reduction (30%) in available phosphorus. The phosphorus balance was significantly (p<0.05) increased in T₅ and T₆ than control. No significant difference was observed in calcium balance. Based on the results obtained in this study, it was inferred that the enzyme addition to corn – soya based diet improved the nutrient utilization.
