Comparative metagenomic and metatranscriptomic analyses reveal the breed effect on the rumen microbiome and its associations with feed efficiency in beef cattle

Microbiome, 2019
BackgroundMicroorganisms are responsible for fermentation within the rumen and have been reported to contribute to the variation in feed efficiency of cattle.

Rumen Microbiome Composition Is Altered in Sheep Divergent in Feed Efficiency

Frontiers in Microbiology, 2020
Rumen microbiome composition and functionality is linked to animal feed efficiency, particularly for bovine ruminants. To investigate this in sheep, we compared rumen bacterial and archaeal populations (and predicted metabolic processes) of sheep ...

The rumen microbiome: a crucial consideration when optimising milk and meat production and nitrogen utilisation efficiency

Gut microbes, 2018
Methane is generated in the foregut of all ruminant animals by the microorganisms present. Dietary manipulation is regarded as the most effective and most convenient way to reduce methane emissions (and in turn energy loss in the animal) and increase ...

Altitude influences microbial diversity and herbage fermentation in the rumen of yaks

BMC Microbiology, 2020
Background Rumen microbiota in ruminants are vital for sustaining good rumen ecology, health, and productivity. Currently, limited information is available regarding the response of yaks ( Bos grunniens ) to fluctuating environments, especially the rumen

Novel Role of Gut‐Derived Roseburia Intestinalis in Safeguarding Intestinal Barrier Integrity and Microenvironment Homeostasis During Arsenic Exposure

Advanced Science, EarlyView.
Arsenic exposure disrupts intestinal barriers and gut microenvironment. Fecal microbiota transplantation (FMT) alleviates arsenic‐induced damage, with gut‐derived Roseburia intestinalis (R.i) identified as a key protective strain. R.i administration counters arsenic toxicity through immunomodulatory pathways and metabolites.
