Korean Hanwoo Cattle (KHC) were utilized to compare existing and modified methods of slaughtering. Carcass traits, loin eye muscle color coordination, physico-chemical attributes, sensory evaluation and proximate composition were assessed. Twelve KHC were slaughtered following 1) CSNHS: non-halal way neck cutting as following captive bolt stunning with pithing and 2) CSHS: halal way neck cutting as following captive bolt stunning without pithing. Loin eye muscle color coordination, physico-chemical attributes and sensory evaluation did not differ significantly subjected to slaughter types (P > 0.05). However, loin eye muscle crude ash content was higher in CSHS group relative to CSNHS (P < 0.05). Pearson's correlation analysis indicated that several traits were affected by slaughter types. Overall, CSHS ensures no negative impact on meat yield and qualitative traits rather led a higher loin eye muscle crude ash content. Therefore, CSHS could be adopted in Korean slaughterhouses with modification of existing practice.
韩国韩牛（KHC）被用于比较现有的和改良的屠宰方法。评估了胴体特性、腰眼肌肉颜色协调性、理化特性、感官评价和近似成分。12 头 KHC 按照以下两种方法之一进行屠宰：1）CSNHS：非清真方式颈部切割，采用管刺法致昏和刺心，2）CSHS：清真方式颈部切割，采用管刺法致昏而不刺心。根据屠宰方式，腰眼肌肉颜色协调性、理化特性和感官评价没有显著差异（P＞0.05）。然而，CSHS 组的腰眼肌肉粗灰分含量高于 CSNHS 组（P＜0.05）。Pearson 相关分析表明，几种性状受到屠宰方式的影响。总的来说，CSHS 确保了肉产量和质量性状不受负面影响，反而导致了更高的腰眼肌肉粗灰分含量。因此，在韩国屠宰场可以采用 CSHS，但需要对现有做法进行修改。
