Preparation of Lentilactobacillus buchneri NCIMB 40788/CNCM I-4323

What it is. Bacterial preparation based on Lentilactobacillus buchneri NCIMB 40788/CNCM I-4323, a naturally occurring strain obtained by fermentation, intended for incorporation into forage at the time of ensiling. It is a technological additive belonging to the functional group of silage additives.

What it is for. This additive is generally used to promote controlled ensiling fermentation and contribute to the aerobic stability of silage upon silo opening. It is intended for all animal species, within the context of forage preservation prior to feeding. Its use fits within common silage-making practices among livestock farmers and feed manufacturers. An associated study evaluated this strain, alone or combined with Lentilactobacillus hilgardii CNCM I-4785, as part of a renewal authorisation application, without setting a use level.

Points to watch. The corresponding regulatory entry (1k20739) was deleted by Regulation 32024R0251; transitional measures allow the sale of existing stocks of feed produced and labelled before 6 February 2025. The current authorisation status should be checked before any new use, and the figures from the associated study should not be taken as recommended use levels.
