A Protein Value for a Phytase - Some Critical Remarks
The main reason for using an exogenous added phytase in feed is to liberate phosphorus (P), bound as phytate, in raw materials. This not only leads to a lower feed cost by reducing the amount of added inorganic P, but also exerts a positive effect on performance by degradation of phytate, which is a known anti-nutritional factor in feed.
