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. 4a22 Adisseo France S.A.S. Endo-1,4-beta-xylanase EC 3.2.1.8 and Endo-1,3(4)-beta-glucanase EC 3.2.1.6 Additive composition Preparation of endo-1,4-beta-xylanase (EC 3.2.1.8) and endo-1,3(4)-beta-glucanase (EC 3.2.1.6) produced by Talaromyces versatilis sp. nov. IMI CC 378536 and Talaromyces versatilis sp. nov. DSM 26702 having a minimum activity of: — solid form: endo-1,4-beta-xylanase 22 000 VU/g and endo-1,3(4)-beta-glucanase 15 200 VU ( 1 ) /g, — liquid form: endo-1,4-beta-xylanase activity of 5 500 VU/ml and endo-1,3(4)-beta-glucanase 3 800 VU/ml. Characterisation of the active substance Endo-1,4-beta-xylanase (EC 3.2.1.8) and endo-1,3(4)-beta-glucanase (EC 3.2.1.6) produced by Talaromyces versatilis sp. nov. IMI CC 378536 and Talaromyces versatilis sp. nov. DSM 26702. Analytical method ( 2 ) For the quantification of endo-1,4-beta-xylanase activity: — viscosimetric method based on decrease in viscosity produced by action of endo-1,4-beta-xylanase on the xylan containing substrate (wheat arabinoxylan). For the quantification of endo-1,3(4)-beta-glucanase activity: — viscosimetric method based on decrease in viscosity produced by action of endo-1,3(4)-beta-glucanase on the glucan substrate barley betaglucan at pH = 5,5 and 30 °C. Chickens for fattening Chickens reared for laying Minor poultry species for fattening and reared for laying — endo-1,4-beta-xylanase 1 100 VU endo-1,3(4)-beta-glucanase 760 VU — 1. In the directions for use of the additive and premixture, indicate the storage conditions and stability to pelleting. 2. For safety: breathing protection, glasses and gloves shall be used during handling. 19 May 2025 ( 1 ) 1 VU (viscosimetry unit) is the amount of enzyme which hydrolyses the substrate (barley betaglucan and wheat arabinoxylan, respectively), reducing the viscosity of the solution, to give a change in relative fluidity of 1 (dimensionless unit)/min at 30 °C and pH 5,5.
