Untreated Contractor mulesed Station mulesed SkinTraction Wrinkle CoUnT Trial 037, 259 dayS poST TreaTmenT aWI has been working with several potential breech flystrike alternatives in recent years. The most prominent is the SkinTraction® intradermal, owned by Cobbett Technologies Pty Ltd, which uses the active ingredient of Sodium Lauryl Sulphate. AWI has been funding and reporting these trials since 2007. Over the past 12 months AWI has also been assisting with early scoping trials on two other potential alternatives, firstly ‘Liquid Nitrogen’ with Steinfort AgVet Pty Ltd of Victoria, to remove breech and tail skin, and secondly the use of ‘Laser’ treatments with Zeta LLC of Colorado USA, to potentially remove wool around the eye, pizzle, breech and tail. The early scoping results for liquid nitrogen have shown a proof of concept:, the laser technique has not demonstrated proof of concept. However both alternatives warrant further investigation. It is important to note that it takes many years to take a technology from proof of concept to commercialisation and there is often a large attrition rate in between. skintraction® The latest R&D results for SkinTraction® were presented at the Breech Strike Technical R&D Update in August 2012 and are available on the AWI website at www.wool.com/flystrikeRnDupdate Results of one of the trials, Trial 037 at nine months post treatment are shown in Figures 1 and 2.
