Slaughterhouse design profoundly affects the welfare of billions of animals annually, with evidence showing that facility layout and handling systems determine suffering outcomes.
Slaughterhouse welfare is determined by a combination of facility design, line speed, staff training, management culture, and oversight mechanisms. Poorly designed handling systems create bottlenecks where animals bunch, turn back, and receive electric prods. High line speeds prevent proper stunning verification. CCTV monitoring has proven more effective than periodic audit inspection at maintaining welfare standards because it removes the Hawthorne effect.
