The cornerstone of ruminant health and performance is the rumen, where forage and feed are converted into energy and microbial protein thanks to the activity of the rumen microflora: bacteria, protozoa and fungi.

When the rumen microbiota is challenged, a ruminal microbial imbalance occurs which impairs fiber digestion, increases acidosis risk, and may trigger inflammation which negatively impacts digestive comfort and well-being.
