mulesed

Mulesing is a surgical procedure performed on sheep, primarily Merino sheep, in Australia. The practice involves the removal of strips of wool-bearing skin from the breech area of a lamb, usually when it is between four and twelve weeks old. The resulting wound is left to heal by secondary intention, meaning it heals naturally from the edges inwards. The main purpose of mulesing is to prevent "flystrike," a condition where blowflies lay their eggs on sheep, leading to maggot infestation and potentially death. The bare, scarred skin that results from mulesing is less attractive to flies and also less prone to wrinkling, which can trap moisture and feces, further attracting flies.

The practice has been controversial due to animal welfare concerns, with many animal rights organizations and consumers advocating for its cessation. Critics argue that mulesing is a painful and unnecessary mutilation that inflicts suffering on lambs. Proponents, however, maintain that it is a necessary and effective tool for preventing flystrike, which can cause significant suffering and economic loss to farmers.

In response to concerns, the Australian sheep industry has been working towards the phased withdrawal of mulesing. This involves promoting alternative methods of flystrike prevention, such as the use of chemical treatments, selective breeding for sheep with less wrinkled skin, and genetic selection against susceptibility to flystrike. The goal is to eliminate the need for mulesing while ensuring the welfare of sheep and the sustainability of the wool industry. Many brands and retailers are increasingly demanding mulesing-free wool.
