Sheep Mulesing Alternatives and Welfare

Mulesing — surgical removal of skin folds around the breech of Merino sheep — is one of the most controversial practices in wool production, with viable welfare-friendly alternatives available.

Key Facts

Mulesing is performed on approximately 70% of Australian Merino sheep to prevent flystrike
The procedure removes strips of skin from the breech area without anaesthesia in most cases
Flystrike (blowfly larval infestation) causes severe welfare harm and death if untreated
Selective breeding for non-wrinkled skin (Wiltipoll and low-wrinkle Merino lines) eliminates the need for mulesing
Pain relief protocols for mulesing are available but not universally adopted

Welfare Considerations

Mulesing causes acute pain from the surgical wound and residual pain during healing. The raw wound is itself susceptible to flystrike during the healing period, potentially causing the very problem the procedure is meant to prevent. The welfare justification depends on comparing the acute pain of the procedure against the chronic, extreme suffering of untreated flystrike. However, selective breeding for non-wrinkled genetics and targeted insecticide treatments offer solutions that avoid both harms. Consumer and retailer pressure has driven significant industry movement toward mulesing-free certification.

What You Can Do

Choose wool products certified as mulesing-free or sourced from non-Merino breeds
Support retailers and brands that have made mulesing-free commitments
Advocate for accelerated industry transition to non-wrinkled sheep genetics
