The objective of this study was to assess welfare of cattle during bleeding after slaughter with or without stunning. A total of 434 bulls were distributed across three slaughter treatments: penetrating captive bolt stunning followed by chest sticking (PCB, N=279), non-penetrating captive bolt stunning followed by halal slaughter (NPCB, N=67) and shechita without previous stunning (SHE, N=88). Four measures of possible consciousness and return to sensibility were recorded 20 and 60 s after bleeding as welfare indicators. They were the frequencies of responses to nostril stimulation and tongue pinch, spontaneous eye blinking, and rhythmic breathing. All responses were absent in stunned cattle at both 20 and 60 s, and in SHE cattle 7, 4, 10, and 100% of the animals presented these responses, respectively. Repeat shots were required for 46% NPCB and 2% PCB (P<0.05). The application of religious slaughter without previous stunning may result in greater risk of cattle suffering, pain and distress at slaughter.
本研究的目的是评估屠宰时放血过程中，有或没有致昏情况下牛的福利状况。总共434头公牛被分配到三种屠宰处理方式中：穿透式击晕枪致昏后进行胸腔刺杀放血（PCB组，N = 279）、非穿透式击晕枪致昏后进行清真屠宰（NPCB组，N = 67）以及未经事先致昏的犹太教屠宰方式（SHE组，N = 88）。放血后20秒和60秒记录了四项可能反映意识和恢复知觉的指标作为福利指标。它们分别是对鼻孔刺激和舌头挤压的反应频率、自发眨眼以及有节律的呼吸。在致昏的牛中，20秒和60秒时所有反应均未出现，而在SHE组的牛中，分别有7%、4%、10%和100%的动物出现了这些反应。NPCB组46%的牛和PCB组2%的牛需要重复枪击（P<0.05）。未经事先致昏的宗教屠宰方式可能会增加牛在屠宰时遭受更多痛苦、疼痛和痛苦的风险。
