【摘要】 利用M-型超声波对怀孕母山羊以及围产期山羊胎儿的心率进行检测,并对三者的检测结果进行比较,以观察分娩前后胎儿的超声心动图之间的相同点和不同点,以及围产期胎儿和成年山羊的超声心动图之间的异同点。并对围产期胎儿心率以及母山羊心率的M-型超声心动图进行分析,以观察围产期胎儿心脏和成年羊心脏不同结构部位博动的超声情况。从而得到健康山羊及围产期胎儿的正常心率的M型超声心动图生理指标,为以后动物的心血管疾病的超声诊断提供数据。更多还原

【Abstract】 Cyetic ewe and fetus and lamb’s heart rates were measured by M-mode ultrasonic apparatus,and the results were compared in order to find the similarity and the difference of ultrasonogram among them.And the M-mode ultrasonogram of fetus and lamb and cyetic ewe’s heart rates were analysed in order to find the instance of the beating of the different part of cyetic ewe and fetus and lamb’s heart by M-mode ultrasonic apparatus.So the biological indexes of the Mmode ultrasonogram of the normal heart rates of healthy goats and fetus were acquired which may provide data for ultrasonic diagnosis of animal cardiovascular disease.更多还原
