Abstract
Simple SummaryResource-limited farmers under communal farming environments slaughter goats for cultural beliefs and meat consumption using indigenous slaughter methods. These methods include transverse neck incision (TNI), piercing with a short spear on the suprasternal notch targeting the heart (SNP), and piercing with a short spear under-shoulder-blade chest-floor point-of-elbow (CFP) targeting the heart to induce insensibility and death. Unsatisfied animal welfare institutes consider these slaughter methods as cruel because goats are slaughtered while sensible; therefore, experiencing pain and suffering before death. In this study, we slaughtered castrates using the above-mentioned methods and collected behavioural responses before slaughter and while bleeding, the total blood expelled during bleeding, the time it took for the blood to be expelled, the time it took the goats to lose sensibility, and time to lose heartbeat. We found that goats slaughtered using CFP lost sensibility faster. We concluded that goats slaughtered using the CFP method experienced less pain and suffering during slaughter and died faster.Resource-limited farmers slaughter goats without stunning. The objective of the current study was to assess the influence of indigenous slaughter methods used by resource-limited households on slaughter stress-related behaviour, bleeding efficiency, and time to post-slaughter trauma of goats. Thirty clinically healthy castrated Nguni goats aged between 15 to 18 months old with body condition score of three were randomly assigned to three non-stunning informal slaughter methods, (1) transverse neck incision (TNI); (2) suprasternal notch piercing in the direction of the heart (SNP); and (3) under-shoulder-blade chest-floor point-of-elbow (CFP) sticking in the direction of the heart. Ten goats were slaughtered using each method. Slaughter method had no effect (p < 0.05) on stress-related behaviour. Rate of bleeding efficiency was highest (p < 0.05) for SNP slaughtered goats. Time to lose sensibility was lowest (p < 0.05) for goats slaughtered using the CFP (55 s) when compared to SNP (68 s) and TNI (75 s) slaughter methods. Time to post-slaughter trauma was highest (p < 0.05) for SNP (247 s) and lowest for TNI (195 s). These findings suggest that goats slaughtered with SNP experienced rapid death when compared to TNI and SNP slaughter methods. It was concluded that the SNP slaughter method is the most effective slaughter technique because it is associated with higher bleeding efficiency and lower time to lose sensibility before death.
Highlights
Slaughter is any procedure which causes the death of an animal for human consumption
Time to loss of sensibility was significantly lowest for goats slaughtered using the chest-floor point-of-elbow (CFP) slaughter method
Time to cardiac arrest was lowest for goats slaughtered using the transverse neck incision (TNI) slaughter method
Summary
Slaughter is any procedure which causes the death of an animal for human consumption. Death is achieved through stunning and bleeding under conventional slaughter or only bleeding for religious slaughter [1]. In conventional slaughter methods, stunning which aims at inducing insensibility through cerebral concussion resulting in cessation of breathing and cardiac function is achieved either through a penetrative captive bolt, electrical, and gas stunning [2]. Bleeding is usually achieved through the neck incision. Slaughter is currently one of the growing areas of public concern where cultural and religious practices are in conflict with conventional slaughter practices. The public concern is expected to further increase because animal welfare institutes enforce slaughter laws without respecting the religious needs of other ethnic groups where slaughter has a spiritual aspect
