Efficacy of the feed additive containing Companilactobacillus farciminis (formerly Lactobacillus farciminis) CNCM I-3740 (Biacton\uae) for chickens for fattening, turkeys for fattening and laying hens (ChemVet dk A/S)

Abstract

Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the efficacy of the additive consisting of Companilactobacillus farciminis (formerly Lactobacillus farciminis) CNCM I-3740 (tradename: Biacton\uae) for chickens for fattening, turkeys for fattening and laying hens. The additive is a preparation containing viable cells of C. farciminis CNCM I-3740 at the minimum concentration of 1  7 109 CFU/g additive. In a previous opinion, the FEEDAP Panel assessed the safety and the efficacy of the product when used in these target species. The Panel concluded that based on the qualified presumption of safety of the active agent, and the lack of concerns deriving from other components of the additive, Biacton\uae was presumed safe for the target animals, consumers and the environment. Regarding the safety for the user, the FEEDAP Panel could not conclude on the potential of the additive to be irritant to skin and eyes or its dermal sensitisation due to the lack of data. However, it concluded that the additive should be considered a respiratory sensitiser. The data provided in the previous assessment to support the efficacy of the additive did not allow drawing conclusions on the efficacy of the additive in any of the target species. The additional information submitted with chickens for fattening and laying hens did not provide sufficient evidence to conclude on the efficacy of Biacton\uae for these target species. No new information was provided that would lead the Panel to reconsider the conclusions already reached on the use of the additive with turkeys for fattening. The FEEDAP Panel, based on the available data, cannot conclude on the efficacy of Biacton\uae in chickens for fattening, turkeys for fattening and laying hens
