Lactobacillus buchner i CNCM I-4323/NCIMB 40788 as a feed additiv e for all animal species 
(Text with EEA relevance) 
THE EUR OPEAN COMMISSION, 
Having regar d to the Treaty on the Functioning of the European Union, 
Having regar d to Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 September 2003 
on additives for use in animal nutr ition (1), and in particular Article 9(2) thereof, 
Whereas: 
(1)  Regulation (EC) No 1831/2003 provi des 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 submitte d for the author is­
ation of a preparation of Lactobacillus hilgardii CNCM I-4785 and Lactobacillus buchner i CNCM I-4323/NCIMB 
40788. That application was accompan ied by the particulars and documents required under Article 7(3) of 
Regulation (EC) No 1831/2003. 
(3) That application concer ns the author isation of a preparation of Lactobacillus hilgardii CNCM I-4785 and Lactoba ­
cillus buchner i CNCM I-4323/NCIMB 40788 as a feed additive for all animal species to be classifie d in the additive 
catego ry ‘technological additives ’. 
(4)  The European Food Safety Author ity (‘the Auth ority’) concluded in its opinion of 2 Octobe r 2018 (2) that, under 
the proposed conditions of use, the preparation of Lactobacillus hilgardii CNCM I-4785 and Lactobacillus buchner i 
CNCM I-4323/NCIMB 40788 does not have an adverse effect on animal health, consumer safety or the 
environment. It also concluded that the additive is considered a potential respirato ry sensitiser and that no 
conclusion could be drawn on skin or eyes sensitisation or irritation by the additive. Theref ore, the Commission 
considers that appropr iate prot ective measures should be taken to prevent adverse effects on human health, in 
particular as regards the users of the additive. The Authority also concluded that the preparation concer ned has 
the potential to improve the production of silage from easy and moderate ly difficult to ensile forage mat erials. The 
Author ity does not consider that there is a need for specifi c requirements of post-market monitori ng. It also 
verified the repor t on the method of analysis of the feed additive in feed submitted by the Reference Laborat ory 
set up by Regulation (EC) No 1831/2003. 
(5)  The assessment of the preparation of Lactobacillus hilgardii CNCM I-4785 and Lactobacillus buchner i CNCM 
I-4323/NCIMB 40788 shows that the conditions for author isation, as provid ed for in Article 5 of Regulation (EC) 
No 1831/2003, are satisfied. According ly, the use of that preparation should be author ised as specifi ed in the 
Annex to this Regulation. 
(6)  The measures provi ded for in this Regulation are in accordance with the opinion of the Standing Committee on 
Plants, Animals, Food and Feed, 15.5.2019 L 126/1 Official Jour nal of the European Union EN

(2)EFSA Jour nal 2018; 16(10):5455. HAS ADOPTED THIS REGUL ATION: 
Article 1 
The preparation specifi ed in the Annex, belonging to the additive catego ry ‘technological additives ’ and to the functional 
group ‘silag e additives’, is author ised as an additive in animal nutr ition, subject to the conditions laid down in that 
Annex. 
Article 2 
This Regulation shall enter into force on the twentieth day followi ng 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 State s.
