Assessment on the Safety and Efficacy of a Feed Additive That Contains Spores of <i>Bacillus paralicheniformis</i> DSM 33902 and <i>Bacillus subtilis</i> DSM 33903 (Bovacillus® 10 and Bovacillus® WS) for Use in Dairy Cows and Other Dairy Ruminants (R

An application was submitted to the Food Standards Agency in December 2023 from Chr. Hansen A/S (‘the applicant’), requesting the use of a new additive consisting of Bacillus paralicheniformis DSM 33902 and Bacillus subtilis DSM 33903 (Bovacillus® 10 and Bovacillus® WS), under the category ‘zootechnical additives’ and functional group ‘gut flora stabiliser’. The additive is proposed to be used in feed and drinking water for dairy cows and other dairy ruminants at a minimum recommended dose of 3.8 x 10 8 CFU/kg complete feed, or minimum 7.4 x 10 7 CFU/l drinking water. To support the Food Standards Agency (FSA) and Food Standards Scotland (FSS) in evaluating the dossier, the Advisory Committee on Animal Feedingstuffs (ACAF) was asked to review the dossier and the supplementary information from the applicant. The FSA/FSS concluded, based on the ACAF’s advice, that the additive was correctly identified and characterised. ACAF concluded that the additive can be considered safe for the target species, the consumer and the environment. The additive should be considered a potential respiratory sensitiser and dermal sensitiser for the user/worker. ACAF concluded that the additive has the potential to be efficacious in dairy cows and other dairy ruminants. The views of ACAF have been taken into account in the safety assessment, which represents the opinion of the FSA and FSS.
