The genomic and proteomic landscape of the rumen microbiome revealed by comprehensive genome-resolved metagenomics
This work offers a comprehensive analysis of more than 6.5 terabytes of Illumina and Nanopore sequence data, including assembly of 4,941 metagenome-assembled genomes, whole-chromosome assemblies of novel rumen bacteria.

Composition of Rumen Bacterial Community in Dairy Cows With Different Levels of Somatic Cell Counts
This research suggests that specific rumen microbes are altered in cows with high SCCs. Cows with high SCCs showed lowered milk and component yield and rumen volatile fatty acids concentration — but these cows also had higher rumen bacterial diversity compared to low SCC cows.

Assembly of 913 microbial genomes from metagenomic sequencing of the cow rumen
This article presents 913 draft bacterial and archaeal genomes from 43 Scottish cattle. Most of these genomes were previously unsequenced strains and species.

Changes in the rumen and colon microbiota and effects of live yeast dietary supplementation during the transition from the dry period to lactation of dairy cows
In this study, researchers made innovative use of endoscopy to sample rumen and colon tissues. This technique offered a unique perspective to study rumen microbiota. The resulting research details the effect of the rumen-specific yeast S. cerevisiae CNCM I-1077 on microbiota changes in both rumen and colon around transition.

Relative reticulo-rumen pH indicators for subacute ruminal acidosis detection in dairy cows
Sub Acute Ruminal Acidosis (SARA) is defined as a drop in rumen pH, but what is the most accurate way to look at these pH variations? This study addressed this important research question and even accounted for individual variabilities.
