Abstract A battery study was conducted to evaluate the efficacy of phytase superdosing in improving growth performance, pancreatic response, and nutrient digestibility of broilers with a high trypsin inhibitor model. There were 5 dietary treatments: positive control (PC), negative control 1 (NC1), NC1+ 1500 U/kg phytase, negative control 2 (NC2), and NC2 + 1500 U/kg phytase.
