Abstract

Euthanasia is a common veterinary medical procedure performed on terminally ill backyard chickens (Gallus gallus domesticus). To reduce stress for these animals, it is important to develop a euthanasia protocol that provides a rapid and humane death. For this prospective research investigation, we evaluated 2 different methods of euthanasia in chickens. Twenty-two adult female leghorn chickens were administered an intravenous (IV, n = 11) or oral transmucosal (OTM, n = 11) 602 mg/kg dose of pentobarbital sodium solution for humane euthanasia. Loss of consciousness (LOC) occurred in 95.4% (21/22) of the birds within 5 minutes. Both apnea and asystole were achieved in 100% (11/11) of the birds in the IV group and 54.5% (6/11) of the birds in the OTM group after 5 minutes; 45.5% (5/11) of the chickens in the OTM group had to be rescued. Birds administered the euthanasia solution IV were found to have faster times to LOC (Mann-Whitney U [MW]=110.5, P < 0.001), asystole (MW: 121, P < 0.001), and apnea (MW: 121, P < 0.001) compared with the OTM chickens. Overall, the OTM route for administering pentobarbital sodium in chickens resulted in a reliable LOC in all but 1 bird; however, it did not result in apnea and asystole for all birds within 5 minutes. Based on the results of this study, the OTM administration of pentobarbital sodium is not a reliable method to euthanize chickens.

戊巴比妥钠经黏膜与静脉给药对白来角鸡人道安乐死的比较。
安乐死是一种常见的兽医程序,对身患绝症的后院鸡(Gallus Gallus domesticus)进行安乐死。为了减轻这些动物的压力,重要的是制定一项安乐死协议,提供快速和人道的死亡。在这项前瞻性研究中,我们评估了两种不同的鸡安乐死方法。采用602 mg/kg剂量戊巴比妥钠溶液经静脉注射(IV, n = 11)或经黏膜口服(OTM, n = 11)对22只成年雌来角鸡进行人道安乐死。95.4%(21/22)的鸟类在5分钟内发生意识丧失。IV组和OTM组在5分钟后分别有100%(11/11)和54.5%(6/11)的鸟类实现呼吸暂停和无搏停止;OTM组有45.5%(5/11)的鸡需要抢救。注射安乐死液IV的鸡出现LOC (Mann-Whitney U [MW]=110.5, P < 0.001)、心脏骤停(MW: 121, P < 0.001)和呼吸暂停(MW: 121, P < 0.001)的时间比注射安乐死液IV的鸡更快。总的来说,给鸡施用戊巴比妥钠的OTM途径在除1只鸡外的所有鸡中产生可靠的LOC;然而,并不是所有的鸟类都在5分钟内出现呼吸暂停和心脏骤停。基于本研究的结果,戊巴比妥钠不是一种可靠的安乐死鸡的方法。
