Sheep must be shorn annually to prevent discomfort from excessive fleece growth. Shearing technique significantly affects welfare outcomes for millions of sheep.
Shearing is a necessary welfare intervention for domesticated wool breeds whose coats do not naturally shed. However, the process itself can cause significant distress if performed by unskilled workers or under poor conditions. Sheep are restrained in stressful positions; if shearers are rushed or rough, the animals may sustain cuts or injuries. The welfare imperative is ensuring that all shearers are properly trained, that sheep are handled calmly, that cold stress is prevented post-shearing, and that wounds are promptly treated.
