Poultry for breeding and for laying — 300 FYT — 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 feed containing more than 0,23 % phytin-bound phosphorus. 3. For safety: breathing protection, glasses and gloves shall be used during handling. 16 March 2021 Other poultry 250 FYT Pigs for breeding and minor porcine species for breeding 750 FYT Other pigs and minor porcine species 500 FYT ( 1 ) 1 FYT is the amount of enzyme that liberates 1 micromole of inorganic phosphate per minute from sodium phytate at pH 5,5 and a temperature of 37 °C.
