This study quantified the welfare of 423 cattle and water buffalo in four Bangladeshi slaughterhouses to identify facility and species-specific factors that influence welfare. The majority of animals arrived at the slaughterhouse with injuries, signs of dehydration and oculo-nasal discharge. During slaughter, buffalo experienced more stabbing at the throat (21%), compared to local cattle (10%, P = 0.011), and significantly more cuts to the neck during slaughter (5.1 ± 1) than Hariana (3.9 ± 1) or local cattle (3.6 ± 1.1; P < 0.001). These results indicated that welfare compromise is common to all species, but that the risk to buffalo was greater. Partial severing of carotid arteries was common and affected time to unconsciousness. There was a statistical interaction between facility and species on the time taken for animals to reach unconsciousness, suggesting that welfare within a location could be improved; however, animal welfare was compromised at all facilities. Immediate welfare improvements could be made by training for effective halal slaughter, and future welfare improvements could be gained by improved facility infrastructure for restraint and halal approved pre-slaughter stunning.
本研究对孟加拉国四个屠宰场的423头牛和水牛的福利状况进行了量化，以确定影响福利的设施和特定物种因素。大多数动物抵达屠宰场时都有受伤、脱水迹象以及眼鼻分泌物。在屠宰过程中，水牛在喉部被刺伤的比例（21%）高于当地牛（10%，P = 0.011），并且在屠宰期间颈部被切割的次数（5.1±1）明显多于哈里亚纳牛（3.9±1）或当地牛（3.6±1.1；P < 0.001）。这些结果表明，福利受损在所有物种中都很常见，但水牛面临的风险更大。颈动脉部分切断很常见，且影响失去意识的时间。在动物达到失去意识所需的时间上，设施和物种之间存在统计学交互作用，这表明特定场所的福利状况可以得到改善；然而，所有设施中的动物福利都受到了损害。通过有效清真屠宰培训可立即改善福利，未来通过改进用于约束的设施基础设施和经清真认证的宰前致昏方式可进一步改善福利。
