Euthanasia is ending life in a way that minimizes or eliminates pain and distress. It requires techniques that induce loss of consciousness followed by cardiac and respiratory arrest and loss of brain function. Although euthanasia is the objective for uncontrollable animal suffering, it is not always possible. Euthanasia of animals using barbiturates or barbituric acid derivatives is impractical for situations that require mass euthanasia of multiple animals. Selection of the most appropriate disposal method depends on number of carcasses, potential environmental impact, climatic conditions, and other factors. Preplanning and training are requirements for proper application of euthanasia procedures and disposal of carcasses.
安乐死是以尽量减轻或消除痛苦和不适的方式结束生命。它需要使用一些技术，先使动物失去意识，然后导致心脏和呼吸停止以及大脑功能丧失。尽管安乐死是为了减轻无法控制的动物痛苦而实施的，但并非总是可行。对于需要大规模处死多只动物的情况，使用巴比妥类药物或巴比妥酸衍生物进行动物安乐死是不切实际的。选择最合适的处理方法取决于尸体数量、潜在的环境影响、气候条件和其他因素。预先规划和培训是正确实施安乐死程序和处理尸体的要求。
