Nine different methods of electrical stimulation with a bi-polar rectal probe, were used on 5 rams. The quantity and quality of semen collected, the time taken to produce ejaculation and the maximum voltage required were compared. Semen of good quality was collected by applying a stimulus every 7 seconds for a period of 3 seconds commencing at 1 volt and increasing by 1 volt at a time. A mean maximum voltage of 5.1 volts produced ejaculation. Electrical stimulation, using a voltage rise of 2 volts applied at 5 sec intervals frequently produced smaller volumes of semen, a greater number of collection failures, and severe physical stress to the rams.
使用双极直肠探头对5只公羊采用9种不同的电刺激方法。比较了所采集精液的数量和质量、产生射精所需的时间以及所需的最大电压。通过从1伏开始每隔7秒施加一次刺激，持续3秒，并每次增加1伏的方式来采集优质精液。平均最大电压为5.1伏时可产生射精。以每隔5秒施加2伏电压上升的方式进行电刺激，常常会导致采集到的精液量较少、采集失败次数较多，并且公羊会承受严重的身体应激。
