Sheep Mulesing Alternatives: Protecting Wool Sheep from Flystrike Humanely

Mulesing is a painful procedure used to prevent flystrike in Merino sheep, and significant welfare progress has been made in developing effective alternatives.

Key Facts

Mulesing involves surgically removing strips of skin from around a sheep rump to prevent fly larvae infestation
The procedure causes acute pain lasting hours to days and is typically performed without anesthetic in many countries
Blowfly strike is itself a severe welfare problem causing intense suffering if untreated
Alternatives including selective breeding for non-wrinkled skin, long-acting insecticides, and clips are increasingly viable
New Zealand completed a voluntary industry shift away from mulesing, demonstrating that change is achievable

Welfare Considerations

Mulesing presents a classic welfare dilemma: a painful procedure performed to prevent a potentially more painful condition. The ethical case for alternatives has driven significant industry investment in selective breeding for plain-bodied, less wrinkle-prone Merino sheep that are naturally more resistant to flystrike. Genetic approaches represent the most sustainable long-term solution, as they eliminate both the need for mulesing and the ongoing need for chemical flystrike prevention. Where mulesing continues, use of local anesthetic and pain relief is increasingly mandated. Major wool buyers have committed to phasing out mulesing in their supply chains.

What You Can Do

Choose wool products from non-mulesed flocks where alternatives are clearly labeled
Support brands that have committed to sourcing from non-mulesed or mulesing-with-pain-relief flocks
Advocate for mandatory pain relief requirements where mulesing continues
