The effect of feeding on the motility of the stomach and small intestine in the pig.

1. Electromyographical studies were made on the motility of the stomach and small intestine of five pigs when given a standard diet either ad lib. or as one or two meals/d. Recordings were made from electrodes placed chronically on the antrum, the duodenum and the jejuno-ileum, and a continuous 24 h recording was made every 2d for a period of 4 weeks. A simple "T"-shaped cannula was positioned in the proximal duodenum in two of the pigs.
