Functional group: digestibility enhancers 4a1613 Société Industrielle Lesaffre Endo-1,4-beta-xylanase EC 3.2.1.8 (Safizym X) Additive composition: Preparation of endo-1,4-beta-xylanase produced by Trichoderma longibrachiatum (CNCM MA 6-10W) having a minimum activity of: Powder form: 70 000 IFP ( 1 ) /g Liquid form: 7 000 IFP/ml Characterisation of the active substance: endo-1,4-beta-xylanase produced by Trichoderma longibrachiatum (CNCM MA 6-10W) Analytical method ( 2 ) : Reducing sugar assay for endo-1,4-beta-xylanase by colorimetric reaction of dinitrosalicylic acid reagent on reducing sugar yield. Ducks — 700 IFP — 1. In the directions for use of the additive and premixture, indicate the storage temperature, storage life, and stability to pelleting. 2. Recommended dose per kilogram of complete feedingstuff: 2 800 IFP. 3. For use in compound feed rich in non-starch polysaccharides (mainly arabinoxylans), e.g. containing more than 50 % wheat. 8.1.2018 ( 1 ) 1 IFP is the amount of enzyme which liberates 1 micromole of reducing sugars (xylose equivalents) from oat xylan per minute at pH 4,8 and 50 °C.
