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 twentieth day following that of its publication in the Official Journal of the European Union .
ANNEX Identification number of the additive Name of the holder of authorisation Additive 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 4a25 Fertinagro Nutrientes S.L. 3-phytase EC 3.1.3.8 Additive composition: Preparation of 3-phytase produced by Komagataella pastoris (CECT 13094) having a minimum activity of: 1 000 FTU ( 1 ) /ml Liquid form Characterisation of the active substance: 3-phytase (EC 3.1.3.8) produced by Komagataella pastoris (CECT 13094) Analytical method ( 2 ) For the quantification of 3-phytase activity in the feed additive: — colorimetric method based on the enzymatic reaction of phytase on the phytate For the quantification of 3-phytase activity in feedingstuffs: — colorimetric method based on the enzymatic reaction of phytase on the phytate – EN ISO 30024 Chickens reared for laying Minor poultry species for fattening or reared for laying or for breeding — 500 FTU 1. In the directions for use of the additive and premixtures, the storage conditions and stability to heat treatment shall be indicated. 2. For users of the additive and premixtures, feed business operators shall establish operational procedures and organisational measures to address potential risks resulting from its use. Where those risks cannot be eliminated or reduced to a minimum by such procedures and measures, the additive and premixtures shall be used with personal protective equipment, including breathing protection. 20 February 2029 ( 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.
