This review aims to explain the influence and characterization of the microbiome in the ruminant digestive system by presenting the knowledge collected so far. The knowledge presented in this work is focused on the main factors affecting the microbiome and the main dependencies that have been found in it so far. The microbiome in the rumen is the first to come into contact with the biomass of the forage and its main purpose is to decompose into smaller particles or compounds. With the gradual increase in knowledge about the microbiome, there is a chance to manipulate it so that the animal continues to live in a symbiotic relationship with it, while reducing greenhouse gas emissions to the environment as well as increasing feed efficiency. Therefore, understanding the influence of the ruminant microbiome is the main step to achieve such results. However, learning the relationship between microorganisms is only at an early stage, because research focuses mainly on taxonomy. Future research should focus on interactions in the ecosystem which is the microbiome, on explaining individual functions and on influence of environmental factors.

反刍动物消化系统的微生物组——综述

本综述旨在通过介绍迄今为止收集到的知识来解释微生物组在反刍动物消化系统中的影响和特征。这项工作中提供的知识集中在影响微生物组的主要因素以及迄今为止在其中发现的主要依赖性。瘤胃中的微生物组最先与草料的生物质接触，其主要目的是分解成更小的颗粒或化合物。随着对微生物组的了解逐渐增加，有机会对其进行操作，使动物继续与其共生关系，同时减少对环境的温室气体排放并提高饲料效率。因此，了解反刍动物微生物组的影响是实现此类结果的主要步骤。然而，了解微生物之间的关系只是处于早期阶段，因为研究主要集中在分类学上。未来的研究应侧重于生态系统（即微生物组）的相互作用，解释个体功能和环境因素的影响。
