Functional group: digestibility enhancers 4a1640 Danisco Animal Nutrition (legal entity Danisco (UK) Limited) 6-phytase EC 3.1.3.26 Additive composition Preparation of 6-phytase (EC 3.1.3.26) produced by Schizosaccharomyces pombe (ATCC 5233) having a minimum activity of: Liquid and solid form: 5 000 FTU ( 1 ) /g Characterisation of the active substance 6-phytase (EC 3.1.3.26) produced by Schizosaccharomyces pombe (ATCC 5233) Analytical method ( 2 ) Determination of 6-phytase EC 3.1.3.26 in feed additive: colorimetric method based on the quantification of inorganic phosphate released by the enzyme from sodium phytate. Determination of 6-phytase EC 3.1.3.26 in feed premixtures and feedingstuff: EN ISO 30024: colorimetric method based on the quantification of inorganic phosphate released by the enzyme from sodium phytate (after dilution with heat-treated whole grain flour). All avian species for fattening other than chickens for fattening, turkeys for fattening and ducks for fattening — 250 FTU 1. In the directions for use of the additive and premixture, indicate the storage temperature, storage life, and stability to pelleting. 2. For use in compound feed containing more than 0,23 % phytin-bound phosphorus. 3. Maximum recommended dose: 1 000 FTU/kg of complete feedingstuff. 4. For safety: breathing protection glasses and gloves shall be used during handling. 9 October 2022 All avian species for laying other than laying hens 150 FTU ( 1 ) 1 FTU is the amount of enzyme which liberates 1 micromole of inorganic phosphate per minute from a sodium phytate substrate at pH 5,5 and 37 °C.
