Learn more about the role of the rumen and lower gut microorganisms and their impact on the host’s performance and health. The ruminant is a fascinating animal due to its ability to convert feed and forage into energy and microbial protein thanks to the activity of its gut microbial community: bacteria, archaea, protozoa, and fungi. Monthly, this page will feature a microbe found in the gut of ruminants. For more information, please contact Dr. Phillip Myer.
