1forms of non stun slaughter
• Halal (some communities permit recoverable stunning)
• Shechita
• Jhatka (Sikh)
• Traditional slaughter
• Emergency euthanasia
2welfare issues of no stunning
• Stress and pain associated with restraint
• Pain from the cut
• Distress associated with delays in the time to loss of consciousness
• Distress from aspiration of blood into the respiratory tract
3how is pain from the cut measured
hard to assess
change in EEG relate to pain
increase in frequency
narrow window for pain before become apoxic
4what can reduce pain after cuttng
post cut stunning
captive bolt gun
5what animal has to longest and most variable time to loss of pain
cattle
sheep are consitent and shorter
6what is the cause of the time discrepency between sheep and cattle
cattle have a basal plexus- supply blood to both sides of brain
sheep dont have the plexus
= enough to delay loss of conciousness
ALSO false aneurysms/ carotid occlusions= retracts intp carotid sheath, ballons and can slow/ stop blood flow. if develop instanltly could be cause of slow loss of conciousness
7does stunning before affect blood loss
nope
8how to reduce the affects of carotid occlusion
cut differently:
high neck cut, C1 (less trachea rings down)= faster unconciousness and less occlulusions. loss of reflexes faster.
9down side of high neck cut
near larynx and bones- can damage the knife
