Preparation of Propionibacterium freudenreichii DSM 33189 and Lentilactobacillus buchneri DSM 12856

What it is. Additive composed of a preparation of two bacterial strains, Propionibacterium freudenreichii DSM 33189 and Lentilactobacillus buchneri DSM 12856, in solid form, containing at least 5 × 10^11 CFU/g in a 1:4 ratio (1 × 10^11 CFU/g of P. freudenreichii and 4 × 10^11 CFU/g of L. buchneri). It belongs to the technological additives, functional group 1k (silage additives).

What it is for. It is used as a silage additive, intended to support the ensiling process of forage. It is authorised for all animal species, without stage or species restriction. When not combined with other microbial silage additives, the minimum inclusion level is 1 × 10^8 CFU per kg of fresh matter, for forage that is easy or moderately difficult to ensile. It is applied at the forage ensiling stage, before storage.

Points to watch. Easy-to-ensile forage is defined as containing more than 3% soluble carbohydrates in fresh matter, and moderately difficult forage between 1.5 and 3.0%. Storage conditions of the additive and premixtures must follow the instructions on the label. Operators must put in place operational procedures and organisational measures to manage risks linked to use, including personal protective equipment (skin and respiratory protection) where risks cannot otherwise be reduced.
