Pre-Slaughter Handling and Stress Reduction

How handling, lairage, and pre-slaughter management affect animal welfare and meat quality, and best practices for minimizing stress.

Key Facts

Pre-slaughter stress elevates cortisol, causes muscle glycogen depletion, and affects meat quality
Lairage (holding) times over 24 hours increase stress in pigs and cattle
Mixing unfamiliar animals in lairage causes aggression and additional stress
High-contrast lighting, sudden movements, and noise are all identified flight-zone activators
Stockmanship quality during pre-slaughter handling is among the most important welfare determinants

Welfare Considerations

Pre-slaughter welfare is the culmination of an animal's life in the food system and deserves specific attention. The journey from farm to slaughter involves loading, transport, unloading, lairage, and movement through the slaughterhouse - each stage is a welfare event. Animals in slaughterhouses often encounter novel, frightening stimuli - unfamiliar people, sounds, smells, and handling methods. Pre-slaughter stress causes genuine animal suffering and also degrades meat quality, creating a direct economic incentive for welfare investment. Evidence-based low-stress handling, appropriate lairage design, and skilled handling staff can significantly improve both welfare and quality outcomes.
