Phytase is added as an animal feed ingredient, improving P uptake, so reducing feed phosphate additive use rates and reducing P concentrations in manures by up to 30%. Phytase has today achieved a 60-80% uptake rate in livestock farms. The company DSM’s phytase is a strong success story of R&D implementation. It is produced from renewable bio-sourced materials by fermentation. See SCOPE Newsletters 78 and 108.
