Turkey slaughter welfare depends critically on pre-slaughter stunning effectiveness, with controlled atmosphere stunning emerging as a more humane alternative to electrical waterbath systems.
Pre-slaughter handling including shackling and transport to the stun bath causes significant fear and stress in turkeys. The inverted position during shackling causes wing flapping and injury. Waterbath systems with inadequate current or misaligned birds result in conscious entry into scalding water - a welfare catastrophe that occurs in a percentage of birds at every session. Controlled atmosphere systems eliminate shackling-related stress and ensure unconsciousness before any pain is experienced.
