The prohibition of antibiotic drugs in animal husbandry to stimulate animal productivity has provoked an active study of alternative substances, including plant extracts. No less interesting for a detailed study of the extracts of plants Eucalyptus viminalis and Scutellaria baicalensis, as information about their effect on ruminant microbiome is extremely scarce. According to the results of phytochemical analysis, 14 small molecules were found in the extract of Scutellaria baicalensis. and 13 in the composition of the extract of the leaves of Eucalyptus viminalis. Analysis of metagenomic sequencing when plant extracts are included in the feed indicates a significant change in the rumen microbiome. The absence of Proteobacteria and Fibrobacteres phyla in the experimental groups, a decrease in the content of Bacteroidetes by 12.0–17.0% and an increase in Firmicutes (p<0.05) and Saccharibacteria (p<0.05) were noted. An increase in the class Clostridia (p<0.05), due to the family Ruminococcaceae (p<0.05) and the genus Ruminococaceace, was found. In the Bacteroidia class in all groups, the family Prevotellaceae, the genus Prevotella, prevailed in most of the groups. Additional inclusion in the diet of plant extracts of Eucalyptus viminalis and Scutellaria baicalensis have a significant impact on the rumen microbiome of the cattle, the taxonomic identification of microorganisms indicates the prevalence of phyloma Firmicutes, Clostridia class and the Ruminococcaceae family, which are responsible for the separation of imperfect migration. Further evaluation of plant matter is needed in the direction of the overall effect on fermentation of feed in the rumen.
