The role of cholinergic mechanisms in the delayed food passage from the crop induced by medium chain triacylglycerol was investigated in the young chicken. Vagotomy altered the crop emptying of chicks given dietary long chain triacylglycerol, but did not alter it in chicks given dietary medium chain triacylglycerol. On the contrary, denervation in the cranial rete and lateral commissure of the gizzard further inhibited the food passage induced by medium chain triacylglycerol. Administration of cisapride, which induces acetylcholine release from the myenteric nerves, and atropine, a muscarinic cholinergic antagonist, both delayed crop emptying of chicks given medium chain triacylglycerol. These results demonstrate that cholinergic factors are not involved in the delayed forward movement of the food containing medium chain triacylglycerol from the crop of chicks.
