Lactobacillus diolivorans DSM 32074 is a technological additive intended to improve the ensiling process at a minimum proposed dose of 1.0 x 108 colony forming units (CFU)/kg fresh material. The bacterial species L. diolivorans is considered by EFSA to be suitable for the qualified presumption of safety (QPS) approach to safety assessment. As the identity of the strain has been clearly established and as no antibiotic resistance of concern was detected, the use of the strain as a silage additive is considered safe for livestock species, for consumers of products from animals fed the treated silage and for the environment. The additive is not a skin or eye irritant but should be considered to have the potential to be a respiratory sensitiser. In the absence of data, no conclusion can be drawn on the dermal sensitisation potential of the additive. Four studies with laboratory-scale silos were made using samples of forage of differing dry matter and water-soluble carbohydrate content. In each case, replicate silos containing treated forage were compared with identical silos containing the same but untreated forage. Lactobacillus diolivorans DSM 32074 added at 1.0 x 108 CFU/kg forage has the potential to extend the aerobic stability of silage prepared from easy, moderately difficult and difficult to ensile material.
