4a7 | BASF SE | Endo-1,4-beta- xylanase (EC 3.2.1.8) and endo-1,4-beta- glucanase (EC 3.2.1.4) | Additive compositionPreparation of endo-1,4-beta-xylanase (EC 3.2.1.8) produced by Aspergillus niger CBS 109.713 and endo-1,4-beta-glucanase (EC 3.2.1.4) produced by Aspergillus niger DSM 18404 having a minimum activity of 5600 TXU and 2500 TGU/g in solid or liquid form----------------Characterisation of active substanceEndo-1,4-beta-xylanase (EC 3.2.1.8) produced by Aspergillus niger CBS 109.713 and endo-1,4-beta- glucanase (EC 3.2.1.4) produced by Aspergillus niger DSM 18404--------------Analytical methodFor quantification of endo-1,4-beta-xylanase in the feed additive, premixtures, feed materials and compound feed:Viscosimetric method based on decrease of viscosity produced by action of endo-1,4-beta- xylanase on the xylan containing substrate (wheat arabinoxylan) at pH = 3,5 and 55 °C.For quantification of endo-1,4-beta-glucanase in the feed additive, premixtures, feed materials and compound feed:Viscosimetric method based on decrease of viscosity produced by action of endo-1,4-beta- glucanase on the glucan containing substrate (barley betaglucan) at pH = 3,5 and 40 °C. | Chickens for fattening and reared for layingLaying hens All minor poultry species for fattening and layingOrnamental birds | - | 280 TXU 125 TGU | - | - 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 skin and breathing protection.
