The preparation specified in the Annex, belonging to the additive category ‘zootechnical additives’ and to the functional group ‘digestibility enhancers’, is authorised as an additive in animal nutrition, subject to the conditions laid down in that Annex.
This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union.
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 4a33 Industrial Técnica Pecuaria S.A Endo-1,4-beta- xylanase and alpha-galactosidase Additive composition Preparation of endo-1,4-beta-xylanase (EC 3.2.1.8) produced by Trichoderma longibrachiatum CBS 139997 and alpha-galactosidase (EC, 3.2.1.22) produced by Aspergillus tubingensis ATCC SD 6740 having a minimum enzyme activity of: 50 AXC ( 1 ) /g of additive and 40 GALU/g ( 2 ) of additive Solid form Chickens for fattening, Chickens reared for laying Minor poultry species for fattening and reared for laying Ornamental birds - 18 AXC 14 GALU - 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, eyes and breathing protection. 26.9.2032 Characterisation of active substance Endo-1,4-beta-xylanase (EC 3.2.1.8) produced by Trichoderma longibrachiatum CBS 139997 and a-galactosidase (EC 3.2.1.22) produced by Aspergillus tubingensis ATCC SD 6740 Analytical method ( 3 ) For the quantification of endo-1,4-beta-xylanase in the feed additive, premixtures and feedingstuffs: — colorimetric method based enzymatic reaction of endo-1,4-beta-xylanase i) on a wheat arabinoxylan substrate (for the feed additive and premixtures) and ii) on an azo-xylan substrate (for feedingstuffs). For the quantification of alpha-galactosidase in the feed additive, premixtures and feedingstuffs: — colorimetric method based on the enzymatic reaction of alpha-galactosidase on the para-nitrophenyl-alpha-D-galactopyranoside substrate ( 1 ) 1Unit of endo-1,4-beta-xylanase activity (AXC) is the amount of enzyme, which liberates 0,058 micromoles per minute of reducing sugars, expressed as xylose equivalents, from a wheat arabinoxylan substrate at pH 4,7 and 30 °C. ( 2 ) 1Unit of alpha-galactosidase activity (GALU) is defined as the amount of enzyme which degrades one micromole per minute of para-nitrophenyl-alpha-D-galactopyranoside at pH 5,5 and 37 °C.
