Sheep Shearing Welfare: Best Practice Guide

Shearing and Sheep Welfare

Shearing is an annual welfare requirement for most domestic sheep breeds — modern wool sheep have lost their ability to naturally shed fleece, meaning shearing is essential to prevent flystrike, overheating, and fleece-related health problems. However, shearing itself involves handling and restraint that causes temporary stress, and poor technique can cause injury.

Why Shearing is Essential

• Prevents blowfly strike — an extremely painful welfare emergency
• Prevents heat stress in hot weather
• Removes daggy, soiled fleece that causes skin disease
• Allows proper inspection of the body condition and skin
• Removes ectoparasites (lice, keds, mites) living in the fleece

Welfare Considerations During Shearing

• Restraint stress: Sheep experience moderate stress during restraint for shearing — cortisol elevations are measurable but temporary.
• Cuts and nicks: Poor technique or dull blades cause skin wounds — most are superficial but require wound treatment to prevent infection and flystrike.
• Cold stress: Freshly shorn sheep are vulnerable to cold and rain for several weeks — timing shearing to avoid cold snaps is a welfare priority.
• Handling injuries: Rough handling during shearing can cause bruising, dislocation, or fractures — calm, skilled shearers reduce this risk.
• Pregnant ewes: Shearing heavily pregnant ewes increases miscarriage risk; pre-lambing shearing requires particular care.

Best Practice for Shearing Welfare

• Use properly trained, experienced shearers — blade and machine options both acceptable when skill is present
• Keep blades/combs sharp — dull blades cause more cuts and require more pressure
• Work at a pace that minimises rough handling without prolonging restraint
• Check weather forecast before shearing — avoid shearing ahead of cold, wet weather
• Provide shelter for freshly shorn sheep for 2-3 weeks
• Treat any cuts promptly with appropriate wound spray or treatment
• Handle pregnant ewes very carefully; avoid shearing in the last 6 weeks of pregnancy if possible

Mulesing

Mulesing — surgical removal of breech skin in Merino sheep to prevent flystrike — is controversial on welfare grounds. The procedure causes acute pain; concerns about chronic wound pain and inadequate pain relief have led New Zealand to ban the practice and Australia to face growing pressure for phase-out. RSPCA and major retailers oppose mulesing without analgesia.

Key Takeaways

Shearing is a necessary welfare intervention for most domestic sheep, but the welfare of the procedure depends critically on shearer skill, timing, and post-shearing management. Skilled, calm shearing with appropriate shelter provision afterwards is the standard that every sheep flock should achieve.
