The principal blood vessels in the neck which are severed at slaughter in commercial poultry processing plants are described. Mechanical slaughtering methods often severed the spinal cord without cutting the carotid arteries. The manual method of slaughter cut one carotid artery plus one jugular vein. The effects of 9 different slaughtering methods on spontaneous and evoked electrical activity in the brain were examined in anaesthetised chickens and ducks. Severing the spinal cord without cutting the carotid arteries was found to result in death from asphyxia, and cutting one carotid artery plus one jugular vein was one of the slowest methods of killing the birds. Inducing a cardiac arrest at electrical stunning was the quickest method of inducing death. Spontaneous activity in the brain was lost before visual evoked activity. The times before loss of spontaneous activity varied between 23 and 233 s according to the method of slaughter and loss of evoked activity ranged between 90 and 349 s after slaughter.
描述了商业家禽加工厂宰杀时颈部被切断的主要血管。机械宰杀方法常常切断脊髓而不切断颈动脉。手工宰杀方法会切断一条颈动脉和一条颈静脉。在麻醉的鸡和鸭身上研究了9种不同宰杀方法对大脑自发和诱发电活动的影响。发现不切断颈动脉而切断脊髓会导致窒息死亡，切断一条颈动脉和一条颈静脉是杀死禽类最慢的方法之一。电击致昏时诱发心脏骤停是最快的致死方法。大脑的自发活动在视觉诱发活动之前消失。根据宰杀方法不同，自发活动消失前的时间在23至233秒之间，宰杀后诱发活动消失的时间在90至349秒之间。
