This study by U.S. researchers quantifies the links between neutral detergent fiber (NDF) intake, diet particle size and ruminal pH. Read

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.
