Shearing is a necessary procedure for domestic sheep that can cause significant distress if done poorly. Understanding best practice helps farmers and welfare advocates assess shearing welfare.
Shearing causes acute stress through restraint and handling, even when done well. The stress response in sheep during shearing is well-documented and is reduced but not eliminated by good technique. Poor shearing practice — rough handling, slow technique, cuts from blades, and rough use of the handpiece — multiplies both the duration and severity of this stress. The welfare of sheep during shearing depends almost entirely on shearer skill and care. High-welfare shearing also ensures the site is not too hot, sheep are in appropriate condition, and animals are handled calmly before, during, and after the procedure.
