rumination

Dictionary: ru·mi·na·tion   (rū'mə-nā'shən)

1. The act of pondering; meditation.
2. The act or process of chewing cud.

noun

The act or process of thinking: brainwork, cerebration, cogitation, contemplation, deliberation, excogitation, meditation, reflection, speculation, thought. See thoughts.

Includes regurgitation, remastication, ensalivation and reswallowing. The regurgitation of fluid reticular contents occurs as a result of a positive lowering of intrathoracic pressure, the arrival of a ruminal contraction at the cardial sphincter at the appropriate time, relaxation of the cardia and reverse peristalsis in the lower esophagus. The regurgitus is compressed at the back of the tongue and the fluid immediately reswallowed. The solid material is chewed for about a minute and reswallowed. The cycle is then ready to recommence. Rumination requires a positive approach by the cow and it is easily dissuaded by fright or food. Called also chewing the cud, cudding.
