The bolus is mixed with saliva, it is chewed, the liquid digesta are squeezed out and swallowed first a n d then the bolus itself is swallowed. The fermentation gases also leave the rumen via the oesophagus. The true outlet from the rumen is the reticulo-omasal orifice. This outlet carries small undigested feed particles, a suspension of microorganisms a n d a mixture of solutes in water from the rumen t o the omasum.
