L 79/57


of 24 March 2015

concerning the authorisation of the preparation of Saccharomyces cerevisiae NCYC R404 as a feed additive for dairy cows (holder of the authorisation Micro Bio-System Ltd)

(Text with EEA relevance)


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,



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.


In accordance with Article 7 of Regulation (EC) No 1831/2003 an application was submitted for the authorisation of a preparation of Saccharomyces cerevisiae NCYC R404. That application was accompanied by the particulars and documents required under Article 7(3) of Regulation (EC) No 1831/2003.


That application concerns the authorisation of a preparation of Saccharomyces cerevisiae NCYC R404 as a feed additive for dairy cows to be classified in the additive category ‘zootechnical additives’.


The European Food Safety Authority (‘the Authority’) concluded in its opinion of 11 September 2014 (2) that, under the proposed conditions of use, the preparation of Saccharomyces cerevisiae NCYC R404 does not have an adverse effect on animal health, human health or the environment. It was also concluded that the additive has the potential to improve milk production of dairy cows. 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 Reference Laboratory set up by Regulation (EC) No 1831/2003.


The assessment of the preparation of Saccharomyces cerevisiae NCYC R404 shows that the conditions for authorisation, as provided for in Article 5 of Regulation (EC) No 1831/2003, are satisfied. Accordingly, the use of that preparation should be authorised as specified in the Annex to this Regulation.


The measures provided for in this Regulation are in accordance with the opinion of the Standing Committee on Plants, Animals, Food and Feed,


Article 1

The preparation specified in the Annex, belonging to the additive category ‘zootechnical additives’ and to the functional group ‘gut flora stabilisers’, 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 twentieth day following that of 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.
