4a7 BASF SE Endo-1,4-beta-xylanaseEC 3.2.1.8Endo-1,4-beta-glucanaseEC 3.2.1.4 
 Additive composition
Preparation 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
5 600 TXU and 2 500 TGU/g
 Liquid form
5 600 TXU and 2 500 TGU/g
 Characterisation of the active substance
endo-1,4-beta-xylanase produced by Aspergillus niger (CBS 109.713)
and endo-1,4-beta-glucanase produced by Aspergillus niger (DSM 18404)
 Analytical method
 For 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 premixture, indicate the storage temperature, storage life, and stability to pelleting.

2. 

— minor poultry species for fattening (other than ducks) and ornamental birds: 280-840 TXU/125-375 TGU,
— chickens reared for laying, turkeys for breeding purposes, turkeys reared for breeding and all minor avian species for laying: 560-840 TXU/250-375 TGU.

3. For safety: breathing protection, glasses and gloves shall be used during handling.
