Rethinking the maximum inclusion levels of exogenous phytase for enhanced turkey production performance
< 0.001) in the retention of calcium, magnesium, iron, potassium, manganese, zinc, and phosphorus, particularly at ≥1000 FTU/kg, Overall, the results confirm that turkeys respond to high PHY inclusion in a manner broadly consistent with broilers. Very high PHY levels (super- and mega-doses) provided continued additional benefits for growth performance beyond 1000 FTU/kg, along with continued improvements in nutrient retention, and the data suggest the optimum dose was beyond that investigated in this study.
