Sheep Welfare at Shearing: Minimising Stress and Injury During Annual Handling

Shearing is an annual welfare-significant handling event for sheep. Low-stress techniques, appropriate shearer training, and minimising wounds and handling time are the primary welfare considerations.

Key Facts

Shearing is necessary for wool breeds to prevent overheating, flystrike, and mobility problems from excessive fleece growth — but the handling process itself causes acute stress and occasionally injury
Physiological studies show that heart rate and cortisol elevation during shearing indicate significant acute stress, with peaks during restraint, initial shearing, and turning manoeuvres
Cuts and nicks from shearing equipment are a common welfare concern — competent shearers using well-maintained equipment inflict significantly fewer wounds than poor-quality shearers
Shearing weather conditions matter: shorn sheep in cold, wet conditions are highly vulnerable to exposure and hypothermia — shearing should be timed appropriately for local climate conditions
Rough handling during mustering and penning before shearing is a significant welfare concern — low-stress herding techniques reduce the pre-shearing fear and stress that accumulate before clipping begins
Mulesing, practiced in Australia to prevent breech flystrike in Merino sheep, involves cutting skin folds without anaesthesia — this is one of the most controversial lamb welfare procedures in the sheep industry
Non-mulesing alternatives including selective breeding for plain-bodied Merinos (Mules Effect), chemical flystrike prevention, and alternative surgical approaches are increasingly available

Welfare Considerations

Shearing is unavoidable for wool breeds but is genuinely stressful for sheep. Restraint in the shearer's position, unfamiliar handling, and the sensory experience of clippers cause acute fear and physiological stress. Cuts from blades cause pain. In the hands of experienced, competent shearers using well-maintained equipment, shearing is relatively quick and minimally injurious. In the hands of poorly trained or rushed shearers, it causes unnecessary injury and prolonged stress. The overall welfare of shearing is therefore primarily determined by shearer quality and farm practice — investment in well-paid, properly trained shearers with maintained equipment is directly reflected in sheep welfare during one of the most significant annual handling events.

What You Can Do

Ensure shearers handling your flock are properly trained and that their equipment is well-maintained and sharp
Time shearing to avoid cold, wet weather conditions that expose freshly shorn sheep to hypothermia risk
Use low-stress mustering and penning practices to minimise fear accumulation before shearing begins
Assess and treat any shearing cuts promptly with antiseptic spray
Support Australian campaigns for the phase-out of mulesing without anaesthesia and transition to pain relief or non-surgical alternatives
Buy wool products certified by the Responsible Wool Standard or ZQ Merino, which include sheep welfare requirements
Support research into better shearing techniques and equipment that reduce handling time and stress
