Description
What it is. Zootechnical additive consisting of a solid preparation of viable spores from three Bacillus amyloliquefaciens strains (PTA-6507, NRRL B-50013, NRRL B-50104), with a minimum total content of 2.5 × 10^9 CFU/g and at least 8.3 × 10^8 CFU/g of each strain.
What it is for. Used as a gut flora stabiliser (functional group 4b) in feed for chickens for fattening, chickens reared for laying, and minor poultry species for fattening or reared for laying. It supports intestinal microbial balance and is compatible with the authorised coccidiostats listed in the regulation (e.g. narasin/nicarbazin, monensin sodium, salinomycin sodium, diclazuril, decoquinate). A related study on a multi-strain Bacillus amyloliquefaciens probiotic illustrates its use in a broiler leaky-gut challenge model, without establishing a dosage recommendation.
Points to watch. The minimum content laid down for poultry is 7.5 × 10^7 CFU/kg of feed; authorisation expires on 3 April 2027. Storage temperature, shelf life and stability under pelleting must be specified in the instructions for use, and operators must implement procedures to manage handling risks, including personal protective equipment where needed.
