AI Article Synopsis
- Cattle brains get blood from different sources, and during slaughter, their carotid arteries can develop problems called false aneurysms, which can affect blood loss.*
- This study looked at whether these false aneurysms happen during religious slaughter (shechita and halal) and after shocking cows to stop their hearts.*
- It found that about 10% of cattle had large false aneurysms during religious slaughter, but none had them when they were electrically stunned with heart failure.*
Article Abstract
It has previously been shown that the cattle brain is supplied with blood via a basi-occipital plexus, in addition to branches from the carotid and basilar arteries. In addition it has been shown during conventional stunning and slaughter that the carotid arteries in cattle can develop false aneurysms at their severed ends and this can curtail exsanguination. This investigation examined whether false aneurysms can occur during religious slaughter, and during bleeding following electrical stunning that simultaneously induced a cardiac arrest. The prevalence of large (>3cm outer diameter) false aneurysms in cattle carotid arteries was 10% for both shechita and halal slaughter. The prevalence of animals with bilateral false aneurysms (at least 2cm in one artery and at least 3cm diameter in the opposite artery) was 7% and 8% for shechita and halal slaughter, respectively. No false aneurysms occurred during bleeding in cattle that were electrically stunned and simultaneously developed a cardiac arrest. The combination of false aneurysms and collateral routes to the brain present a risk of sustained consciousness during religious slaughter in cattle.
