Summary. In connection with such problems as population growth, scarcity of resources and climate change problems, possible development and implementation of livestock technologies that simulate the work of the rumen of ruminants and increase food production, is of particular interest today. For this reason, it is important to have a comprehensive study of species composition and mechanism of commensal interactions of microorganisms in the rumen microbiome of ruminants, depending on various factors. Genome sequencing of these organisms and assembling draft genomes from metagenomic data will bring us closer to completing a comprehensive genome reference collection for the possibility of artificial reproduction of the microbial community. This review is aimed at analyzing the results of the latest metagenomic, metataxonomic and metatranscriptome studies based on next generation sequencing (NGS), affecting various aspects of the rumen microbiome, such as the effect of feed additive or diet on the rumen microbiome, the dependence of the composition of rumen microbiome on host genetics, early signs of young rumen colonization, a variety of enzymes, etc. Fundamental questions regarding the composition of the rumen microbiome, the ability of its communities to assemble during the life of an animal and the predictability of assembly processes are still not resolved. Further research that furthers a deeper understanding of the structure and function of the rumen microbiome will enable us to potentially predict and determine how and when we can interfere with the microbiome assembly process to modulate this ecosystem.

Key words: ruminants, cattle, rumen microbiome composition, bioreactor, sequencing, genetics.
