Mulesing in Sheep Farming: The Welfare Debate and Alternatives

Mulesing — surgical removal of skin around the breech of Merino sheep — is practised in Australia to prevent fatal flystrike. The procedure causes significant pain and is increasingly contested as alternatives improve.

Key Facts

Mulesing involves removing skin folds around the hindquarters of Merino lambs, typically without anaesthesia
The procedure causes acute pain lasting days, and chronic pain during healing lasting up to 8 weeks
Blowfly strike (flystrike) kills affected sheep within days if untreated — it is a genuine welfare threat
Pain relief use during mulesing remains inconsistent across Australian farms despite being widely available
Alternatives including selective breeding for plain-bodied sheep, crutching, and topical treatments are increasingly viable

Welfare Considerations

Mulesing presents a genuine welfare dilemma — the procedure causes significant pain, but untreated flystrike causes severe suffering and death. The strongest welfare case supports eliminating mulesing through selective breeding for sheep with less skin folding, combined with improved flystrike monitoring and treatment. Where mulesing continues, mandatory pain relief (meloxicam and/or local anaesthesia) substantially reduces suffering. Many major wool buyers now require suppliers to commit to mulesing-free sourcing timelines. Consumer and retailer pressure, combined with investment in breeding alternatives, is accelerating the transition away from the practice.

What You Can Do

Choose wool products certified as mulesing-free or sourced from operations committed to its elimination
Support retailers and brands that have committed to mulesing-free supply chains
Advocate for mandatory pain relief during any mulesing procedure as an immediate welfare improvement
Support research into selective breeding programmes for naturally flystrike-resistant Merino sheep
