The most common method for the on-farm euthanasia of neonate piglets is reported to be manual blunt force trauma. This paper presents the results of research to evaluate a mechanical non-penetrating captive bolt (the Accles and Shelvoke CASH small animal tool, Birmingham, UK) to produce an immediate stun/kill with neonate piglets. One hundred and forty-seven piglets (average dead weight = 1.20 kg ± 0.58 (standard deviation, SD), mean age = 5.8 days (median = 3)) were euthanized with the device and demonstrated immediate loss of consciousness, subjectively assessed by behavioural signs and no recovery. The result that 147 out of 147 animals were effectively stun/killed gives a 95% confidence interval for the true percentage of animals that would be effectively stun/killed of 97.5-100% with the use of the CASH small animal tool under the conditions of the current study. This research concludes that the CASH small animal tool, using a 1 grain brown coded cartridge, is suitable for producing a stun/kill in neonate piglets when applied in a frontal/parietal position.
据报道，农场中对新生仔猪实施安乐死最常见的方法是人工钝器创伤。本文介绍了一项研究结果，该研究旨在评估一种机械式非穿透性击晕枪（英国伯明翰的阿克斯和谢尔沃克CASH小型动物工具）对新生仔猪进行即时击晕/致死的效果。用该设备对147头仔猪（平均死亡体重 = 1.20千克±0.58（标准差，SD），平均年龄 = 5.8天（中位数 = 3天））实施安乐死，通过行为迹象主观评估显示，这些仔猪立即失去意识且未恢复。在当前研究条件下，147头动物中有147头被有效击晕/致死，据此得出使用CASH小型动物工具时，能被有效击晕/致死的动物真实百分比的95%置信区间为97.5% - 100%。本研究得出结论，使用1格令棕色编码弹药筒的CASH小型动物工具，应用于额部/顶部位置时，适用于对新生仔猪进行击晕/致死。
