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 feed with a moisture content of 12 % Category of zootechnical additives. Functional group: digestibility enhancers. 4a8i Roal Oy Endo-1,4-beta-xylanase (EC 3.2.1.8) Additive composition Preparation of endo-1,4-beta-xylanase produced by Trichoderma reesei CBS 114044 having a minimum activity of: solid form: 160 000 BXU ( 1 ) /g liquid form: 160 000 BXU/g Characterisation of the active substance Endo-1,4-beta-xylanase (EC 3.2.1.8) produced by Trichoderma reesei CBS 114044 Analytical method ( 2 ) Characterisation of the active substance in the additive and the premixture: reducing sugar assay for endo-1,4- beta-xylanase by colorimetric reaction of dinitrosalicylic acid reagent on reducing sugar yield at pH 5,3 and 50 °C; Characterisation of the active substance in the compound feed: colorimetric method measuring water soluble dye released by the enzyme from azurine crosslinked wheat arabinoxylan substrate. Chickens for fattening and chickens reared for laying - 8 000 BXU - 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 their use. Where those risks cannot be eliminated by such procedures and measures, the additive and premixtures shall be used with personal protective equipment, including breathing, skin and eye protection for solid forms, and breathing protection for liquid forms. 20 July 2033 Turkeys for fattening and turkeys reared for breeding 16 000 BXU Piglets (weaned) 24 000 BXU ( 1 ) 1 BXU is the amount of enzyme which liberates 1 nmol reducing sugars as xylose from birch xylan per second at pH 5,3 and 50 °C.
