Shearing is a necessary annual welfare procedure for most sheep breeds that causes acute stress, with shearing technique and handling practices significantly affecting the welfare impact.
Shearing causes acute but short-lived stress for most sheep, with the fear of restraint and handling being the primary welfare concern rather than the shearing itself when performed by competent shearers. Inexperienced or rough handling, inappropriate restraint positions, and cuts from poor technique significantly worsen welfare during shearing. Thermal stress from post-shearing cold exposure, particularly in late-winter or early-spring shearing, adds a welfare dimension that must be managed with appropriate shelter provision. The welfare goal is not to avoid shearing - unsheared wooled breeds develop significant welfare problems - but to minimize the stress and discomfort through good technique and facilities.
