View Complete Answer & Explanation
Question (English)
Commercial method for stunning of pig is:
- CO₂ gas stunning ✓ Correct
- Captive bolt pistol
- Electric stunning
- Percussion stunner
Explanation:
Correct Answer: CO₂ Gas Stunning
The commercial method of stunning pigs in large-scale abattoirs is CO₂ gas stunning (chemical stunning). This is used because it allows continuous, high-throughput processing without manual handling stress.
CO₂ Gas Stunning Parameters
- Concentration: 70% CO₂ + 30% O₂
- Exposure time: 45 seconds
- Mechanism: CO₂ blocks nerve endings → anaesthesia/unconsciousness
- Advantage: No physical contact needed; pigs walk in voluntarily (reduces stress)
Compare: Most Suitable vs Commercial Method for Pigs
- Most suitable method for pigs = Chemical (CO₂) stunning ✓
- Commercial method for pigs = CO₂ gas stunning ✓ (same in this case)
Stunning by Species
- Cattle/Buffalo → Mechanical (captive bolt pistol)
- Sheep/Goat/Pig → Electrical (alternating current, 250 mA, 75V, 10 sec)
- Pigs (commercial/large scale) → CO₂ gas stunning
- Poultry → Electric water bath
