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 CBS 143953 with a minimum activity of 40 000 U/g ( 1 ) Characterisation of active substance Endo-1,4-beta-xylanase (EC 3.2.1.8) produced by Trichoderma reesei CBS 143953 Analytical method ( 2 ) For quantification of endo-1,4-beta-xylanase activity: colorimetric method measuring water soluble dye released by action of endo-1,4-beta-xylanase from azurine cross-linked wheat arabinoxylan substrates All poultry species - 625 U - 1. In the directions for use of the additive and premixture, 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 or reduced to a minimum by such procedures and measures, the additive and premixtures shall be used with personal protective equipment, including eyes and breathing protection. 20.12.2031 Pigs for fattening Piglets (weaned and suckling) All minor porcine species 2 000 U ( 1 ) 1 U is the amount of enzyme which releases 0,48 μmol of reducing sugar (xylose equivalent) per minute from wheat arabino xylan at pH 4,2 and 50 °C.
