With this adjustable apparatus sheep aged from five months to five years and varying in mass from 16-95 kg could be restrained effectively. Cercarial suspension was split by only 2/44 sheep during infestation with Schistosoma mattheei. Using a battery of seven cages, it was possible to infest 23 sheep, each for 30 minutes, in one day. No cercariae were more than 4-1/2 hours old at the end of exposure.
借助这种可调节装置，年龄在5个月至5岁之间、体重在16至95千克之间的绵羊能够得到有效约束。在用马氏血吸虫感染期间，只有2/44的绵羊出现尾蚴悬浮现象。使用一组七个笼子，一天内可以感染23只绵羊，每只感染30分钟。在暴露结束时，尾蚴的存活时间不超过4个半小时。
