To improve goat meat quality in rural communities, it is important to evaluate the effects of indigenous slaughter methods used by resource-limited farmers when performing traditional ceremonies on the meat physico-chemical characteristics. The current study assessed the effects of the meat physico-chemical characteristics of Nguni goats slaughtered with the transverse neck incision (TNI), suprasternal notch piercing (SNP) and the under shoulder blade piercing at the chest floor point of elbow (CFP) to the direction of the heart methods. Thirty Nguni weathers were randomly assigned to three slaughter treatments (10 goats/treatment). (LTL) was sampled at post-mortem for physico-chemical characteristic measurements. Meat from wethers slaughtered with the SNP method had greater ultimate pH values than meat from wethers slaughtered with TNI and CFP slaughter methods. Wethers slaughtered with the SNP method had lower meat redness (), yellowness (), and chroma (*) values than those slaughtered with TNI and CFP slaughter methods. Goat slaughter method did not affect meat drip loss, water holding capacity, cooking loss and shear force. Overall, Nguni wethers slaughtered with the TNI and CFP methods produced chevon with fresher meat appearance than those slaughtered using the SNP method.
为了改善农村社区的山羊肉品质,评估资源有限的农民在举行传统仪式时使用的本土屠宰方法对肉的理化特性的影响很重要。当前的研究评估了采用横向颈部切口(TNI)、胸骨上切迹穿刺(SNP)以及从肘的胸底点(CFP)向心脏方向的肩胛下穿刺方法屠宰的恩古尼山羊的肉理化特性的影响。30只恩古尼阉公羊被随机分配到三种屠宰处理方式(每种处理10只山羊)。宰后采集腰大肌(LTL)用于理化特性测量。采用SNP方法屠宰的阉公羊的肉的最终pH值高于采用TNI和CFP屠宰方法的阉公羊的肉。采用SNP方法屠宰的阉公羊的肉的红色度()、黄色度()和色度(*)值低于采用TNI和CFP屠宰方法的阉公羊。山羊屠宰方法对肉的滴水损失、持水力、烹饪损失和剪切力没有影响。总体而言,采用TNI和CFP方法屠宰的恩古尼阉公羊生产的山羊肉比采用SNP方法屠宰的阉公羊生产的山羊肉外观更新鲜。
