COMMISSION IMPLEMENTING REGUL ATION (EU) 2020/1371 
of 1 Oct ober 2020

as a feed additiv e for lactating sows (holder of the author isation BASF SE) 
(Text with EEA relevance) 
THE EUR OPEAN COMMISSION, 
Havi ng regar d to the Treaty on the Functioning of the European Union, 
Havi ng rega rd to Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 Sept ember 2003 on 
additives for use in animal nutr ition (1), and in particular Article 9(2) thereof, 
Whereas: 
(1) Regulation (EC) No 1831/2003 provid es for the author isation of additives for use in animal nutr ition and for the 
grounds and procedures for granting such author isation. 
(2) In accordance with Article 7 of Regulation (EC) No 1831/2003 an application was submitted for the author isation 
of a preparation of endo-1,4-beta-xylanase and endo-1,4-beta-g lucanase. That application was accompanied by the 
particulars and documents required under Article 7(3) of Regulation (EC) No 1831/2003. 
(3) The application concer ns the author isation of a preparation of endo-1,4-beta-xylanase (EC 3.2.1.8) produced by 
Aspergillus niger CBS 109.713 and endo-1,4-beta-g lucanase (EC 3.2.1.4) produced by Aspergillus niger DSM 18 404 
as a feed additive for lactating sows to be classifie d in the additive catego ry ‘zootec hnical additives’ and in the 
functional group ‘digestibility enhancers ’. 
(4) The European Food Safety Author ity (‘the Author ity’) concluded in its opinion of 29 Januar y 2020 (2) that, under the 
proposed conditions of use, the preparation of endo-1,4-beta-xylanase (EC 3.2.1.8) produced by Aspergillus niger CBS 
109.713 and endo-1,4-beta-g lucanase (EC 3.2.1.4) produced by Aspergillus niger DSM 18 404 does not have an 
adverse effect on animal health, consumer safety or the environment. It was also concluded that the additive should 
be considered as a potential skin and respirator y sensitiser . Theref ore, the Commission considers that appropr iate 
prote ctive measures should be taken to prevent adverse effects on human health, in particular as regar ds the users 
of the additive. The Author ity concluded that the additive is efficacious as a zootec hnical additive in improving the 
diges tibility of the diets in lactating sows. The Author ity does not consider that there is a need for specific 
requirements of post-market monitor ing. It also verified the repor t on the method of analysis of the feed additive in 
feed submitted by the Reference Laborator y set up by Regulation (EC) No 1831/2003. 
(5) The assessment of the preparation of endo-1,4-beta-xylanase (EC 3.2.1.8) produced by Aspergillus niger CBS 109.713 
and endo-1,4-beta-g lucanase (EC 3.2.1.4) produced by Aspergillus niger DSM 18 404 shows that the conditions for 
author isation, as provided for in Article 5 of Regulation (EC) No 1831/2003, are satisfied. According ly, the use of 
that preparation should be author ised as specified in the Annex to this Regulation. 
(6) The measures provid ed for in this Regulation are in accordance with the opinion of the Standing Committ ee on 
Plants, Animals, Food and Feed, 
HAS ADOPTED THIS REGUL ATION: 
Article 1 
The preparation specified in the Annex, belonging to the additive categor y ‘zoot echnical additives ’ and to the functional 
group ‘diges tibility enhancers’, is author ised as an additive in animal nutr ition, subject to the conditions laid down in that 
Annex.
