Sheep shearing is a necessary welfare practice for domesticated sheep that cannot naturally shed wool, but shearing methods and handler skill significantly affect welfare outcomes.
Sheep welfare at shearing depends primarily on handler skill and technique. Well-executed shearing by experienced handlers causes brief, manageable stress with minimal injury. Poor technique causes cuts, bruising, and prolonged struggling that causes more significant welfare impact. Mulesing - the removal of skin folds around the breech to prevent fly strike - causes acute pain comparable to surgical procedures and chronic post-operative pain during healing. Despite its welfare cost, mulesing prevents the potentially worse welfare outcome of fly strike, creating a genuine trade-off. Breeding solutions including plain-bodied Merinos that don't require mulesing offer the welfare-positive long-term alternative. Consumer and retailer demand for non-mulesed wool has accelerated the transition to alternative approaches in major producing regions.
