Explanation:
Correct Answer: Electric Water Bath
The commercial method of stunning poultry (broilers, layers) in processing plants is the electric water bath (wet electrical stunner).
How the Electric Water Bath Works
- Live birds are hung upside down on a moving shackle line.
- Their heads are immersed in an electrically charged water bath.
- Current passes through the brain → immediate unconsciousness.
- Birds then pass to the automatic neck-cutting machine for bleeding.
Advantages of Electric Water Bath for Poultry
- Suitable for high-throughput poultry processing (thousands of birds per hour).
- Consistent and uniform stunning across all birds.
- Reduces struggling and wing flapping that causes bruising.
