欧盟评估布氏乳杆菌DSM29026作为所有动物青贮饲料添加剂的安全性和有效性

 

　　经过评估，专家小组认为该添加剂对目标物种、消费者和环境是安全的。

 

　　且最低浓度为5×107 CFU/kg的布氏乳杆菌DSM 29026可提高易青贮饲料产量。部分原文报道如下：

 

　　Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed （FEEDAP ） was asked to deliver a scientific opinion on Lactobacillus buchneri DSM 29026 when used as a technological additive to improve ensiling of forage. The additive is intended for use with all forages and for all animal species at a proposed minimum concentration of 1 × 10⁸ colony‐forming units （CFU ）/kg forage if used alone, or 5 × 10⁷ CFU /kg forage if used in combination with other authorised microorganisms. The bacterial species L. buchneri is considered by the EFSA to be suitable for the qualified presumption of safety approach to safety assessment. As the identity of the strain has been clearly established and no acquired antimicrobial resistance determinants of concern were 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. In the absence of data, the FEEDAP Panel cannot conclude on the potential of the additive to be a skin/eye irritant or skin sensitiser. Given the proteinaceous nature of the active agent, the additive should be considered a respiratory sensitiser. The FEEDAP Panel concluded that Lactobacillus buchneri DSM 29026 at a minimum concentration of 5 × 10⁷ CFU /kg may improve the production of silage from easy and moderately difficult to ensile forage material.
