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 4a1603 Novozymes A/S Endo-1,3(4)-beta-glucanase (EC 3.2.1.6) Additive composition Preparation of endo-1,3(4)-beta-glucanase (EC 3.2.1.6) produced by Aspergillus fijiensis CBS 589.94 with a minimum activity of: Coated form: 50 FBG ( 1 ) /g. Liquid form: 120 FBG/mL Characterisation of the active substance Endo-1,3(4)-beta-glucanase produced by Aspergillus fijiensis CBS 589.94 Analytical method ( 2 ) For the quantification of 1,3(4)-beta-glucanase activity in the feed additive: colorimetric method measuring coloured compound produced by the dinitro salicylic acid (DNSA) based on the enzymatic hydrolysis of beta-glucan at pH 5,0 and 50 °C. For the quantification of 1,3(4)-beta-glucanase activity in premixtures and compound feed: colorimetric method measuring water soluble dyed fragments based on the enzymatic hydrolysis of cross-linked azo-barley-glucan at pH 4,5 and 50 °C. Chickens for fattening Weaned piglets - 10 FBG - 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 by such procedures and measures, the additive and premixtures shall be used with personal breathing, eye and skin protective equipment. 20 July 2033 ( 1 ) One glucanase unit (FBG) corresponds to the amount of enzyme which under standard conditions (pH 5,0 and 30 °C) liberates glucose or other reducing carbohydrates at a rate corresponding to 1 μmol glucose per minute.
