Pre-slaughter stunning is the primary tool for minimizing suffering at slaughter, and understanding the different methods and their effectiveness is essential for welfare-conscious advocacy.
Stunning technology, when properly applied, dramatically reduces the suffering of slaughter. The gap between best practice and common practice is significant, however. Equipment failures, inadequate training, and high line speeds all compromise stunning effectiveness. The choice of stunning method also matters — CO2 stunning for pigs causes documented distress during induction that better alternatives can avoid. Welfare-focused regulation must address both technology standards and implementation quality.
