The reactions of pigs to the vibration and noise components of transport were examined with the use of an apparatus which simulated these factors. The pigs were trained to switch off the apparatus by pressing a switch panel with their snouts. It was found that vibration was aversive but that noise was not. The pigs switched off the apparatus more frequently when the vibration was fast and when they had been fed a large meal before the test. Although the sedative tranquillizing drug azaperone decreased the number of times the apparatus was switched off, the effect appeared to be non-specific because azaperone also reduced the number of responses that pigs would make in order to receive food.
利用一种模拟运输中振动和噪音因素的装置，研究了猪对这些因素的反应。训练猪用鼻子按压开关面板来关闭该装置。结果发现，振动是令人厌恶的，但噪音不是。当振动速度快且在测试前给猪喂了大餐时，猪更频繁地关闭装置。尽管镇静安定药物阿扎哌隆减少了装置被关闭的次数，但这种效果似乎是非特异性的，因为阿扎哌隆也减少了猪为获取食物而做出的反应次数。
