Mulesing - removing skin folds around a sheep's hindquarters without anaesthetic - remains controversial, with alternatives developing but not yet universally adopted.
Mulesing causes acute and lasting pain - the procedure removes strips of skin without anaesthetic, and wound healing takes weeks. Even proponents acknowledge the severe welfare cost and justify it against the alternative risk of flystrike. The availability of anaesthetic and analgesic products means that where mulesing continues, pain relief is increasingly available but not universally used. The industry transition to non-mulesing alternatives is real but slow.
