The preparation specified in the Annex, belonging to the additive category ‘zootechnical additives’ and to the functional group ‘digestibility enhancers’, is authorised as an additive in animal nutrition subject to the conditions laid down in that Annex.
This Regulation shall enter into force on the 20th day following its publication in the Official Journal of the European Union .
ANNEX Identification number of the additive Name of the holder of authorisation Additive (Trade name) Composition, chemical formula, description, analytical method Species or category of animal Maximum age Minimum content Maximum content Other provisions End of period of authorisation Units of activity/kg of complete feedingstuff with a moisture content of 12 % Category of zootechnical additives. Functional group: digestibility enhancers 4a5 AB Enzyme GmbH 6-phytase EC 3.1.3.26 (Quantum Phytase 2500 D Quantum Phytase 5000 L) Additive composition 6-phytase produced by Pichia pastoris (DSM 15927) having a minimum activity of: Solid form: 2 500 FTU/g ( 1 ) Liquid form: 5 000 FTU/ml Characterisation of the active substance 6-phytase produced by Pichia pastoris (DSM 15927) Analytical method ( 2 ) Colorimetric method based on reaction of vanadomolybdate on organic phosphate produced by reaction on a phytate-contaning substrate (sodium phosphate) at pH 5,5 and 37 °C. Chickens for fattening — 500 FTU — 1. In the directions for use of the additive and premixture, indicate the storage temperature, storage life, and stability to pelleting 2. Recommended dose per kilogram of complete feedingstuff: — chickens for fattening: 500-2 500 FTU — laying hens: 2 000 FTU — ducks for fattening: 250-2 000 FTU — turkeys for fattening: 1 000 -2 700 FTU — piglets (weaned): 100-2 500 FTU 3. For use in compound feed containing more than 0,25 % phytin-bound phosphorus 4. For use in weaned piglets until approximately 35 kg 5. For safety: breathing protection glasses and gloves shall be used during handling 8.7.2018 Laying hens — 2 000 FTU — Ducks for fattening — 250 FTU — Turkeys for fattening — 1 000 FTU — Piglets (weaned) — 100 FTU — ( 1 ) 1 FTU is the amount of enzyme which liberates 1 micromole of inorganic phosphate per minute from sodium phytate at pH 5,5 and 37 °C.
