Research Progress of mixed silage and its Application in ruminant production
Mixed silage is a process of mixing two or more silage raw materials in closed silage containers,mainly relying on lactic acid bacteria under anaerobic conditions,producing lactic acid to reduce pH and inhibit the growth of harmful bacteria,so as to preserve the nutrients of silage raw materials.Mixed silage can obtain nu-trient-rich silage by utilizing the complementarity of nutrients among raw materials and dynamic changes of mi-crobial community,which can improve rumen degradation rate of ruminants,so as to improve production per-formance and sustainable development level of ruminants.The modulation mode of mixed silage and its fermenta-tion quality,the microbial community structure of mixed silage and the application of mixed silage in the produc-tion of ruminants were reviewed in this paper,which provided reference for the preparation and application of high quality mixed silage.
