瘤胃作为反刍动物体内的饲料加工厂，其内环境稳定和微生物区系的平衡影响着动物对饲料的利用，日粮精粗比的改变影响瘤胃内环境稳态以及微生物区系组成，从而影响反刍动物的生产效率。本文综述了日粮精粗比影响瘤胃pH、NH3-N浓度、VFA浓度和瘤胃微生物区系组成的研究进展，为在生产实践中提高反刍动物生产效率提供理论依据。

As the ruminants’ feed mills in the body,rumen affect the utilization of feed through it’s internal environment and microbial flora balance.Change the forage-to-concentrate ratios could affect the rumen internal environment and rumen microbial flora,thereby affecting the production efficiency.The latest research progress of different forage-to-concentrate ratios controlling rumen pH, concentration of NH3-N, VFA, and rumen microbial flora were summarized in this paper, provide a theoretical basis for improving the productivity of ruminants in the pro-duction practice.
