Study Notes

Mulesing Overview

Mulesing is the removal of wool-bearing skin from the breech of a sheep to prevent flystrike, a parasitic infection from fly larvae.
The wool in the breech area can trap feces and urine, attracting flies that cause flystrike.
Scar tissue resulting from mulesing does not attract flies, thereby reducing flystrike susceptibility.
It is a common practice in Australia, particularly with Merino sheep known for their high wool production.

Mulesing Procedure and Impact

Considered a skilled surgical task, mulesing can only prevent flystrike in the affected area, not elsewhere on the sheep's body.
National Farmers Federation of Australia claims that mulesing is the most practical method to prevent flystrike, saving millions of sheep from death.
The Australian Veterinary Association acknowledges welfare implications but supports mulesing as a necessary practice in the absence of humane alternatives.

Controversy and Animal Rights Perspectives

Animal rights organizations, including PETA, label mulesing as cruel and advocate for more humane alternatives.
Australian wool industry previously pledged to phase out mulesing by 2010 but later abandoned this commitment, leading to criticism from animal welfare groups.
New Zealand's wool industry began phasing out mulesing in 2007, officially banning it by October 2018.

Flystrike and Wool Production Background

The Australian sheep blow fly, an invasive species, is attracted to Merino sheep due to their wrinkled skin that traps dirt and feces.
The practice of mulesing originated in the early 1930s when a rancher inadvertently discovered that removing skin reduced fly attraction following healing.

Mulesing vs. Crutching

Mulesing involves permanent skin removal for flystrike prevention, while crutching is periodic wool removal that does not provide permanent protection.
Frequent crutching reduces flystrike incidence but is less effective than mulesing.

Pain Management and Regulation

Mulesing requires accreditation and training for practitioners, typically done during other procedures like tail docking.
Mulesing causes pain, with no required pre or post-operative pain relief according to Australian law, though analgesics are often applied.
Codes of practice since 2006 prohibit mulesing in sheep older than 12 months.

Alternatives and Non-Surgical Solutions

Freeze branding (steining) has emerged as a non-surgical alternative, aiming to prevent wool growth without the same level of pain associated with mulesing.
Breeding programs focus on creating Merino sheep with less skin wrinkling to reduce flystrike susceptibility.
Research is ongoing into insecticides, topical treatments, and biological controls to manage flystrike without surgical procedures.

Industry Impact and Fashion Retailer Responses

Several international retailers, including Abercrombie & Fitch and Liz Claiborne, have boycotted Australian Merino wool due to ethical concerns surrounding mulesing.
Public and celebrity pressure has intensified the demand for alternatives, leading to research funding for non-mulesing methods.
Animal welfare groups advocate for a focus on breed modification and dietary interventions to minimize flystrike risk without surgical intervention.
