Rumen Digestion and Rumination

Oral digestion undergoes a tremendous intensification in the act of rumination. This proceeds in the opposite direction to fodder-uptake. What the cow has grazed, tasted, and swallowed, it brings back up again in portions from a deeper digestive zone, the forestomachs, chews it and tastes it through once more — and now for the first time thoroughly. Depending on the kind of fodder, whether fresh green or roughage, it carries out 30 to 80 rumination strokes per portion.
