Impact of exopolysaccharide production by microbial inoculants on the quality and digestibility of silage

乳制品生产商表示，青贮料存在问题，影响了他们生产质量稳定的牛奶的能力。通过对养殖场微生物群落的管理，可以提高青贮饲料的质量。Lallemand动物营养公司对青贮料质量和使用接种剂开发生物控制策略感兴趣。然而，需要更多的知识来了解这些生防剂的优点和缺点，以便将它们的使用定向到适当的应用条件。特别是，细菌接种剂产生的胞外多糖对青贮过程中微生物群落组成以及由此产生的青贮质量和消化率的影响尚未得到彻底的调查。该项目旨在产生可用于管理微生物相互作用的知识，以提高青贮料的质量。丰富的关于生产环境中微生物群落的知识库将导致改进指导方针和战略，并将这些指导方针和战略转给生产者。

Dairy producers have expressed problems with silage that impact their ability to produce milk with consistent quality. Silage quality can be improved through management of microbial communities on the farm. Lallemand Animal Nutrition is interested in silage quality and developing biocontrol strategies using inoculants. However, more knowledge is needed to understand the strengths and weaknesses of these biocontrol agents in order to target their use to the proper conditions for application. In particular, the impact of exopolysaccharides produced by bacterial inoculants on the composition of microbial communities during the ensiling process and the resulting silage quality and digestibility has not been thoroughly investigated. This project aims to generate knowledge that can be used to manage microbial interactions to improve silage quality. An enriched knowledge base on microbial communities in the production environment will lead to improved guidelines and strategies that will be transferred to producers.
