Bacillus velezensis (PTA-6507), Bacillus velezensis (NRRL B-50013) and Bacillus velezensis (NRRL B-50104)

Additive Zootechnical additives Authorised in animal feed (EU)

Description

What it is. This additive is a solid preparation of viable spores from three Bacillus velezensis strains (PTA-6507, NRRL B-50013 and NRRL B-50104), produced by fermentation. It has a minimum total content of 2.5 × 10^9 CFU/g of additive, with at least 8.3 × 10^8 CFU/g for each strain.

What it is for. It belongs to functional group 4b, gut flora stabilisers, and is authorised for turkeys for fattening at a minimum level of 7.5 × 10^7 CFU/kg complete feed. It is intended to support intestinal microbial balance in this species. It may be combined with the authorised coccidiostats lasalocide A sodium, monensin-sodium and diclazuril. A related EFSA assessment on another Bacillus velezensis strain (Correlink™ ABS747) illustrates ongoing interest in this type of additive for growing poultry, but does not set usage levels for this product.

Points to watch. The instructions for use must state storage conditions and stability to heat treatment. Feed business operators must put in place operating procedures and organisational measures to manage risks for users, including respiratory protection where risks cannot otherwise be reduced. Authorisation is limited to turkeys for fattening and runs until 15 December 2031.
