Brain function was examined in adult cattle after conventional captive bolt stunning or shechita slaughter, using eight animals in each treatment. The times to loss of evoked responses (visual and somatosensory) and spontaneous activity in the electro-corticogram were used to determine the onset of brain failure. Captive bolt stunning followed by sticking one minute later resulted in immediate and irreversible loss of evoked responses after the stun. Spontaneous cortical activity was lost before sticking in three animals, and in an average of 10 seconds after sticking in the remaining five animals. The duration of brain function after shechita was very variable, and particularly contrasted with captive bolt stunning with respect to the effects on evoked responses. These were lost between 20 and 126 seconds (means of 77 seconds for somatosensory and 55 seconds for visual evoked responses) and spontaneous activity was lost between 19 and 113 seconds (mean 75 seconds) after slaughter.
在成年牛接受传统的 captive bolt 击晕或犹太教屠宰法宰杀后，对其脑功能进行了检查，每种处理方式使用八只动物。通过诱发反应（视觉和体感）消失的时间以及脑电图中的自发活动来确定脑功能衰竭的开始。先用 captive bolt 击晕，一分钟后放血，击晕后诱发反应立即且不可逆转地消失。在三只动物中，自发皮层活动在放血前就已消失，在其余五只动物中，平均在放血后 10 秒消失。犹太教屠宰法后脑功能持续的时间差异很大，特别是在对诱发反应的影响方面与 captive bolt 击晕形成鲜明对比。屠宰后，诱发反应在 20 至 126 秒之间消失（体感诱发反应平均为 77 秒，视觉诱发反应平均为 55 秒），自发活动在 19 至 113 秒之间消失（平均 75 秒）。
