Mulesing Alternatives in Sheep Welfare

The welfare debate around mulesing and the development of alternatives to prevent flystrike in Merino sheep.

Key Facts

Mulesing involves surgically removing folds of skin around the breech of Merino sheep to prevent flystrike
The procedure causes significant acute pain and is typically performed without adequate anaesthesia
Flystrike — blowfly larvae infesting moist skin folds — causes severe and potentially fatal suffering
Pain relief for mulesing is increasingly available and mandated in some jurisdictions
Alternatives including selective breeding for bare-breech phenotype, chemical control, and barrier methods are advancing
Australia is the largest producer of Merino wool and has faced international pressure to phase out mulesing

Welfare Considerations

Mulesing represents a genuine welfare dilemma: it causes acute pain but prevents potentially worse suffering from flystrike. The welfare case against mulesing as currently practiced — often without adequate pain relief on large numbers of lambs — is strong, particularly as alternatives improve. The welfare case for mandatory pain relief as an immediate interim measure is compelling and already supported by evidence of efficacy. Longer-term, selective breeding for bare-breech genetics reduces the need for surgical intervention entirely, representing the most welfare-optimal pathway for the industry. Consumer demand for non-mulesed wool is a meaningful driver of industry progress.

What You Can Do

Choose certified non-mulesed wool products where available
Support retailers and brands that have committed to phasing out mulesed wool from their supply chains
Advocate for mandatory pain relief for any mulesing still performed in transitional periods
Support research into bare-breech breeding programmes that eliminate the need for mulesing
Engage with the wool industry about timelines and support for complete mulesing phase-out
