Cud

Cud, the sudden bolus of hastily swallowed fodder which ruminants drive from their paunch and honeycomb stomach back again into the mouth. There the cud is leisurely chewed, and the semifluid result passes down again into the stomach, usually into the manyplyes. One bolus is driven upwards after another until the greater part of the cropped herbage has been chewed. See RUMINANTS.
