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.**

乳制品生产商表达了青贮饲料的问题，影响了他们生产质量稳定的牛奶的能力。通过对农场微生物群落的管理可以提高青贮饲料的质量。Lallemand Animal Nutrition对青贮饲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物防治剂的优点和缺点，以便将其用于适当的应用条件。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的影响以及由此产生的青贮饲料质量和消化率尚未得到彻底研究。该项目旨在产生可用于管理微生物相互作用以提高青贮饲料质量的知识。关于生产环境中微生物群落的丰富知识库将有助于改进指导方针和战略，并将其转交给生产者。
