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 4a1642 Lyven Endo-1,4-beta-xylanase EC 3.2.1.8 Additive composition Preparation of endo-1,4-beta-xylanase produced by Trichoderma koningii (MUCL 39203) having a minimum activity of: Solid form: 1 500 AXC ( 1 ) /g Liquid form: 200 AXC/ml Characterisation of the active substance endo-1,4-beta-xylanase produced by Trichoderma koningii (MUCL 39203) Analytical method ( 2 ) For quantification of endo-1,4-beta-xylanase produced by Trichoderma koningii (MUCL 39203) in feed: Colorimetric method based on the quantification of dyed oligomers produced by the action of endo-1,4-beta-xylanase on Remazol-Brilliant-Blue-R xylan at pH 4,7 and 30 °C Turkeys for fattening Turkeys reared for breeding — 75 AXC — 1. In the directions for use of the additive and premixture, indicate the storage temperature, storage life and stability to pelleting. 2. Recommended maximum dose per kilogram of complete feedingstuff for turkeys for fattening and turkeys reared for breeding: 100 AXC. 3. For use in feed rich in non-starch polysaccharides (mainly arabinoxylans) 4. For safety: breathing protection, glasses and gloves shall be used during handling. 3 January 2023 ( 1 ) 1 AXC is the amount of enzyme which liberates 17,2 micromoles of reducing sugars (maltose equivalents) from oat xylan per minute at pH 4,7 and 30 °C.
