Efficacy of the feed additive consisting of Bacillus velezensis NRRL B‐67257 (Correlink™ ABS747) as a feed additive for all growing poultry species (Elanco GmbH)
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the efficacy of a product consisting of viable spores of Bacillus velezensis NRRL B‐67257 as a zootechnical additive for chickens for fattening, chickens reared for laying, turkeys for fatten...

| description | Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the efficacy of a product consisting of viable spores of Bacillus velezensis NRRL B‐67257 as a zootechnical additive for chickens for fattening, chickens reared for laying, turkeys for fattening, turkeys reared for breeding and minor poultry species. The additive has the tradename Correlink™ ABS747 Bacillus subtilis and is not currently authorised in the European Union. It is intended for use in complete feed for the target species at a minimum inclusion level of 1.5 × 108 CFU/kg complete feed. In a previous opinion the FEEDAP Panel could not conclude on the efficacy of the additive for the poultry species due to the potential cross‐contamination of the control diets in two of the three studies provided. The applicant has provided supplementary information to exclude this possibility. The new data showed that the gene used as marker in the previous analyses is non‐specific of the NRRL B‐67257 strain, which precluded the adequate quantification of the active agent in the feeds used in the studies. Moreover, in a second analysis, the active agent could not be isolated from the field excreta samples collected from either from the treated or the control group of one of the formerly submitted efficacy studies. The Panel concluded that the methodology was not able to discriminate between the strain under assessment and the background. Therefore, the FEEDAP Panel was not in the position to conclude on the efficacy of Correlink™ ABS747 for all growing poultry species based on the data newly provided. |
