The enzyme as 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 4a11 Danisco Animal Nutrition (legal entity Danisco (UK) Limited) Endo-1,4-beta-xylanase EC 3.2.1.8 Additive composition Preparation of endo-1,4-beta-xylanase (EC 3.2.1.8) produced by Trichoderma reesei (ATCC PTA 5588) with a minimum activity of 40 000 U/g ( 1 ) Characterisation of the active substance endo-1,4-beta-xylanase (EC 3.2.1.8) produced by Trichoderma reesei (ATCC PTA 5588) Analytical method ( 2 ) For quantification of endo-1,4-beta-xylanase activity: colorimetric method based on the quantification of water soluble dyed fragments produced by the action of endo-1,4-beta-xylanase on azurine cross-linked wheat arabinoxylan at pH 4,25 and 50 °C. Minor poultry species other than ducks — 625 U 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 rich in starch and non-starch polysaccharides (mainly beta-arabinoxylans). 27 November 2022 ( 1 ) 1 U is the amount of enzyme which liberates 0,5 μmol of reducing sugar (expressed as xylose equivalents) from a cross-linked oat spelt arabinoxylan substrate at pH 5,3 and 50 °C in one minute.
