The motor pattern of the small intestine of the sheep fed ad libitum is characterized by the regular occurrence of myoelectric complexes comprising a phase of regular and irregular spiking activities. Each complex is propagated along the ovine small intestine at a mean velocity of 17 cm/min and originated on the duodenal bulb at 70-100 mn intervals. Reduction and increase in duration of the phase of irregular spiking activity of the complex occurred during fasting and overfeeding respectively. Reduction in spiking activity is paralleled by an increased velocity of propagation whilst a lower migration and a reduced number of the complexes are characteristic of overfeeding. It is concluded that duration, number and velocity of propagation of the myoelectric complexes are adaptative factors in changes of the intestinal flow rate.
随意采食的绵羊小肠运动模式的特征是，肌电复合波有规律地出现，该复合波包括规则和不规则的锋电位活动阶段。每个复合波沿绵羊小肠以平均17厘米/分钟的速度传播，每隔70 - 100分钟在十二指肠球部产生。复合波不规则锋电位活动阶段的持续时间在禁食期间缩短，在过度喂食期间延长。锋电位活动的减少与传播速度的增加同时出现，而过度喂食的特征是复合波的迁移速度降低和数量减少。得出的结论是，肌电复合波的持续时间、数量和传播速度是肠道流速变化中的适应性因素。
