　　Commission Regulation （EU） No 337/2011

　　of 7 April 2011

　　concerning the authorisation of an enzyme preparation of endo-1,4-beta-xylanase and endo-1,3（4）-beta-glucanase as feed additive for poultry, weaned piglets and pigs for fattening （holder of the authorisation Danisco Animal Nutrition）

　　（Text with EEA relevance）

　　THE EUROPEAN COMMISSION,

　　Having regard to the Treaty on the Functioning of the European Union,

　　Having regard to Regulation （EC） No 1831/2003 of the European Parliament and of the Council of 22 September 2003 on additives for use in animal nutrition [1], and in particular Article 9（2） thereof,

　　Whereas:

　　（1） Regulation （EC） No 1831/2003 provides for the authorisation of additives for use in animal nutrition and for the grounds and procedures for granting such authorisation.

　　（2） In accordance with Article 7 of Regulation （EC） No 1831/2003, an application was submitted for the authorisation of the preparation specified in the Annex to this Regulation. The application was accompanied by the particulars and documents required under Article 7（3） of Regulation （EC） No 1831/2003.

　　（3） The application concerns the authorisation of the preparation specified in the Annex as a feed additive for poultry, weaned piglets and pigs for fattening, to be classified in the additive category "zootechnical additives".

　　（4） The European Food Safety Authority （the Authority） concluded in its opinion of 10 November 2010 [2] that the preparation specified in the Annex, under the proposed conditions of use, does not have an adverse effect on animal health, human consumer health or the environment, and that this additive has the potential to improve the zootechnical parameters of the target species. The Authority does not consider that there is a need for specific requirements of post-market monitoring. It also verified the report on the method of analysis of the feed additive in feed submitted by the European Union Reference Laboratory for Feed Additives set up by Regulation （EC） No 1831/2003.

　　（5） The assessment of the preparation specified in the Annex shows that the conditions for authorisation, as provided for in Article 5 of Regulation （EC） No 1831/2003, are satisfied. Accordingly, the use of this preparation should be authorised as specified in the Annex to this Regulation.

　　（6） The measures provided for in this Regulation are in accordance with the opinion of the Standing Committee on the Food Chain and Animal Health,

　　HAS ADOPTED THIS REGULATION:

　　Article 1

　　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.

　　Article 2

　　This Regulation shall enter into force on the 20th day following its publication in the Official Journal of the European Union.

　　This Regulation shall be binding in its entirety and directly applicable in all Member States.

　　Done at Brussels, 7 April 2011.
