R&D update

Mulesing alternative top R&D priority

Australian Wool Innovation Limited (AWI) has to date invested more than $8 million and earmarked up to $15 million into R&D for more effective breech flystrike prevention and control, including the development of alternatives to surgical mulesing. It is a top priority of the R&D program.

Research into genetics, bio-controls, the blowfly genome, different management techniques, plus new non-surgical alternatives such as the natural protein collagenase are all being fast tracked as much as possible to get one or more practical, pain-free alternatives to mulesing to market as quickly as possible, together with improved flystrike prevention and control techniques.

Here is 'Part 1' of a two part snapshot of the latest developments within major projects:

1. Collagenase natural protein

What is it? The development of a natural protein, collagenase, which when applied results in bare skin together with tightening of the skin in that area, replicating the effects of mulesing once the skin has healed.

Latest news: This work is being undertaken by the University of Adelaide and clinical trials to date have been very promising. Field trials are planned for October 2005.

2. Alternative compounds

What is it? AWI is investigating the potential of an additional two compounds that when applied, like collagenase, may deliver a similar result to mulesing.

Latest news: This research is currently subject to confidentiality restrictions. However, if early clinical work is successful, one or both of the compounds may be included in the October field trials.

3. Compound applicators

What is it? The development of a practical and effective applicator for the use of the collagenase or other compounds as an alternative to mulesing.

Latest news: AWI has funded four specialist companies to develop practical and cost effective injection devices for the collagenase or any other compound that may be developed as an alternative to mulesing.

4. Genetics

What is it? AWI is looking at sires with a possible genetic mutation that are completely wool free in the crutch and inner hind legs. Research is looking at the extent and mode of inheritance of this trait, and whether it is possible to identify a gene marker for the trait. In addition, AWI is investing in a project looking at breeding sheep less susceptible to breech flystrike.

Latest news: Trials will clearly establish the degree of resistance that can be conferred by breeding, the impact on other traits, and the most efficient ways to breed such sheep.

5. Pain relief

What is it? The use of a longer acting analgesic which it is hoped could provide 24 - 48 hours pain relief after the mulesing procedure.

Latest news: A feasibility study into the development of the analgesic is underway.
