Two hundred and fifty (250) day old commercial broiler chicks were distributed randomly in to five treatments. Each treatment was having 5 replicates of 10 birds each. T1 ration was kept as control (without phytase), T2, T3, T4 and T5 rations contained phytase enzyme supplemented at the rate of 500, 1000, 2000 and 3000 FTU/Kg of feed, respectively. The phosphorous level (%) in the broiler starter diet of birds fed T1, T2, T3, T4 and T5 ration was 0.43, 0.33, 0.30, 0.27 and 0.24, respectively. The phosphorous level (%) in the broiler finisher diet of birds fed T1, T2, T3, T4 and T5 ration was 0.42, 0.26, 0.23, 0.20 and 0.18, respectively.enPoultry ScienceStudyThesis
