4a7 | BASF SE | Endo-1,4-beta-xylanaseEC 3.2.1.8Endo-1,4-beta-glucanaseEC 3.2.1.4 | Additive compositionPreparation of endo-1,4-beta-xylanase produced by Aspergillus niger (CBS 109.713) and endo-1,4-beta-glucanase produced by Aspergillus niger (DSM 18404) having a minimum activity of:- Solid form:5600 TXU and 2500 TGU/g
- Liquid form:5600 TXU and 2500 TGU/g
Characterisation of the active substanceendo-1,4-beta-xylanase produced by Aspergillus niger (CBS 109.713) and endo-1,4-beta-glucanase produced by Aspergillus niger (DSM 18404)Analytical methodFor quantification of endo-1,4-beta-xylanase activity: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 activity: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. | Minor poultry species for fattening (other than ducks for fattening) and ornamental birds | — | 280 TXU125 TGU | — | - 1.In the directions for use of the additive and premixtures, the storage conditions and stability to heat treatment shall be indicated.
- 2.Recommended doses per kilogram of complete feedingstuffs:
- minor poultry species for fattening (other than ducks) and ornamental birds: 280-840 TXU/125- 375 TGU,
- chickens reared for laying, and all minor avian species for laying: 280-840 TXU/125- 375 TGU,
- turkeys for breeding purposes, turkeys reared for breeding: 560-840 TXU/250-375 TGU.
- 3.For users of the additive and premixtures, feed business operators shall establish operational procedures and organisational measures to address potential risks resulting from its 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 breathing protection and skin protection.
