CO2 Stunning — Full Details
- Species: Pigs (primarily)
- Concentration: 70% CO2 + 30% O2
- Duration: 45 seconds
- Mode of action: CO2 blocks nerve endings in the brain → unconsciousness without pain
- Function in meat quality: Reduces stress → reduces glycogen depletion → reduces PSE incidence
Why Not Used in Cattle?
CO2 stunning is impractical for large animals like cattle and buffalo because of the large enclosed chamber required and their resistance to anaesthetic gases. Mechanical stunning (captive bolt) is more practical and reliable for bovines.
