The slaughter of horses raises significant welfare concerns at every stage: transport to slaughter, lairage conditions, and killing methods. Ensuring dignified end-of-life for horses requires engagement with this difficult subject.
Horse slaughter welfare is a subject that generates intense public emotion but requires clear-eyed welfare analysis. The fundamental welfare question is not whether horses are slaughtered — in many countries this is legal and involves animals from legitimate agricultural contexts — but whether the conditions of transport, lairage, and killing meet acceptable welfare standards. The evidence on long-distance transport to slaughter is concerning: horses transported many hours show elevated stress indicators, injury rates from fighting in unfamiliar groups, and food and water deprivation. Slaughter facilities vary enormously in their ability to handle horses humanely: the prey animal neurology that makes horses effective at detecting and responding to threat also makes them acutely sensitive to slaughterhouse environments. Humane veterinary euthanasia avoids all of these concerns but is not economically viable for all owners, particularly those facing sudden financial crisis with horses. The welfare policy challenge is creating systems that ensure all horses, including unwanted horses, reach end of life in conditions that minimize suffering regardless of economic route.
