The experiments were carried out on 5 sheep with chronic fistulae of the rumen and of the fundus and pyloric part of the abomasum. The motor activity of the parts of the stomach containing fistulae was recorded by the balloon method. The analysis of the obtained contraction curves showed that the motor activity of the pyloric part was more intense than that of the fundus of the abomasum, and the intensity increased with filling of the multichamber stomach with food, food intake increased the tonus and the intensity of peristaltic movements in the fundus and pyloric part of the abomasum, rumination had no effect on the motor activity of the fundus but increased usually the frequency of contractions of the pyloric part. It has been demonstrated also that the movements of the pyloric part of the abomasum can be inhibited for short time periods.
实验是在5只患有瘤胃以及皱胃底部和幽门部慢性瘘管的绵羊身上进行的。通过气囊法记录含有瘘管的胃部各部分的运动活性。对所获得的收缩曲线的分析表明，幽门部的运动活性比皱胃底部更强，并且随着多室胃充满食物，其强度增加，食物摄入增加了皱胃底部和幽门部的紧张度以及蠕动运动的强度，反刍对皱胃底部的运动活性没有影响，但通常会增加幽门部的收缩频率。还已证明，皱胃幽门部的运动可在短时间内受到抑制。
