Mulesing — surgical skin removal around sheep hindquarters — is practiced to prevent flystrike but causes significant pain and has driven consumer campaigns demanding welfare alternatives.
Mulesing creates a wound that takes 4-8 weeks to heal fully and causes documented pain, fear, and stress during and after the procedure. While the welfare harm of flystrike is genuine and severe, performing surgery without analgesics on millions of animals reflects a legacy of treating farm animal pain as economically inconvenient rather than morally obligatory. Transition pathways exist through pain relief adoption, genetic programs selecting away from susceptible body conformations, and improved surveillance technology. These transitions require investment but are technically achievable.
