What is the Stunning process in poultry slaughter? Why is stunning necessary? What precautions should be taken during stunning?
Electrical stunning in poultry slaughter, a key link between pre-slaughter and bleeding, widely uses water-bath variable-frequency tech to ensure animal welfare and improve meat quality.
Poultry stunning process: dim pre-stun prep → water-bath immersion → bleed within 9-30s → 60s spontaneous recovery check.
The core function of the electrical stunning process： ensures operator safety, boosts bleeding efficiency, cuts defective rates, meets welfare standards, stabilizes meat quality.
Key Precautions for Electrical Stunning Operations： control species-specific parameters, avoid over-stunning, stabilize equipment, ensure personnel safety, adapt to poultry variations.
