The effectiveness of captive bolt stunning in the poll position was evaluated in eight anaesthetised sheep. Brain function following shooting was assessed using cortical visual evoked responses (VERs). Immediately following shooting, VERs were abolished in all sheep. However, in five of the sheep, VERs gradually recovered; responses became evident in these animals in a mean (+/- SE) time of 50 +/- 16.7 seconds. These results suggest that captive bolt shooting in the poll position can be associated with rapid recovery of brain function. Because such recovery could be associated with return of sensibility, shooting in the poll position should only be used when essential (ie, in horned animals) and then always followed promptly by sticking.
在八只麻醉的绵羊身上评估了在头顶位置使用栓击式致昏的效果。使用皮层视觉诱发电位（VERs）评估射击后的脑功能。射击后立即，所有绵羊的VERs均消失。然而，在五只绵羊中，VERs逐渐恢复；这些动物的反应在平均（±标准误）50±16.7秒的时间内变得明显。这些结果表明，在头顶位置进行栓击式射击可能与脑功能的快速恢复有关。由于这种恢复可能与感觉恢复有关，因此仅在必要时（即有角动物）才应在头顶位置进行射击，并且随后应立即进行刺杀放血。
