Abstract

In six adult goats, the motility pattern of the stomach and the proximal part of the duodenum was studied by means of electro-myography. Special attention was paid to the motility at the fundus and pyloric antrum of the abomasum.
Normally the myo-electrical contractions of the fundus and pyloric antrum are more stronger than that of the other gastric compartements. In this study, it was found that the amplitude and duration of the spiking activity at gastro-intestinal tract following inflation of a rubber balloon inside the abomasum varied from one organ to another. The motility was low and all organs of the digestive tract, which decreased in the frequency in were sélected to study.Fundus and pyloric antrum of the abomasum were greatly affected during abomasal distension. Migrating myo-electrical activity returned to the normal pattern, just after removal of the abomasal inflation strimulus.
