摘　　要：采用活体瘤胃运动测定装置,测定山羊日粮中添加小麦面筋蛋白条件下瘤胃运动的变化。结果表明:4只山羊试验期与对照期相比,瘤胃平滑肌收缩力平均提高31.2%,差异极显著(P<0.05)。15 min内,瘤胃平均蠕动持续时间延长34.1%,差异显著(P<0.05)。瘤胃蠕动频率下降25.1%,差异显著(P<0.05)。建立的瘤胃运动检测装置能够灵敏地检测山羊瘤胃运动变化规律。同时利用家兔小肠体外培养装置检测到小麦面筋蛋白通过瘤胃微生物降解作用生成的阿片肽活性,为反刍动物瘤胃代谢调控的研究提供理论依据。Wheat gluten protein was added to the diet of goats to determine the changes of rumen movements with the rumen dynamic determination device. Compared with control period, the results of four goats in experiment period showed that, the average contract power of the goat＇s rumen was significantly increased by 31.2% （P〈0.05）, the average of rumen peristalsis continued time were prolonged significantly by 34. 1% （P〈0.05）in 15 minutes. As a contrast, rumen peristalsis frequency of the goats was decreased remarkably by 25.1%（P〈0.05）. The determination device of rumen movement could sensitively observe change regulations of ruman movements in goats. At the same timer activities of opioid peptides from gluten protein degradated by rumen microbes were detected with the device of intestine of rabbits cultured in vitro. This provides theoretical base for the study on the control of rumen metabolism in ruminants.
