The technique of partial exteriorization of the reticulum and
rumen of the sheep is briefly described. Partial exteriorizations have
been used to study the motility of the reticulum and rumen and to
observe the effects of dietary factors on the motility. A characteristic
pattern of motility is present in animals fasted until their stomach
contents have become freely liquid. The pattern alters when the animals
feed. The changes include, in addition to changes such as an increase in
the frequency of co-ordinated contractions, a change in the form of the
co-ordinated contractions. The extent of the changes in form, and their
persistence after feeding stops appears primarily determined by the
nature of the feed and the amount eaten. The origin of the changes and
their possible effects on gastric functions are briefly discussed.
