Wool Stocktake : AWI Annual Report 2012-13
Sheep health, welfare and productivity (continued) Research based at Armidale (CSIRO) and Mt Barker (Department of Agriculture and Food WA) into the breeding of breech strike resistant sheep continued with further divergence between the resistant and susceptible lines. Dags, Breech Wrinkle, Urine Stain and Breech Cover are the lead indicator traits although there are other as yet undetermined traits, likely to be odours that repel or attract flies that influence the risk of breech strike. Sniffer dogs can differentiate wool from the two lines of sheep. Results are disseminated via newsletters, FlyBoss, breeder presentations and updates on the AWI website at www.wool.com Trials of the SkinTractionTM intradermal breech strike prevention method by Cobbett Technologies continued with promising results. A decision on registration through the APVMA is now due February 2014. A "proof of concept" was achieved for the application of Liquid Nitrogen to breech and tail wrinkle to reduce wrinkle and breech wool cover. Trials to improve the applicator and efficiency of the application have commenced. A "proof of concept" was not achieved for the use of lasers to permanently remove from breech and tail but warrant further investigations which will continue in 2013 /14. Trials using combinations of pre and post-operative pain relief continue. A project with the University of Melbourne to complete the gene sequencing of the remaining 50 per cent of the fly genome commenced, to be followed by an assessment of this information for fly prevention chemicals and future resistance. Field sampling has been completed on broad populations of sheep blowfly to enable testing for cryomazine and dicyclanil resistance. This will help determine whether the risk of a low level resistant population of the NSW Monaro is an isolated case or just one representative of a new phenotype found in other locations. Extension of the outcomes of the research and how breeders can best address the risk of breech flystrike are available on the Sheep CRC's FlyBoss website and workshops and the AWI website at www.wool.com Six monthly meetings with animal welfare groups continue allowing two-way feedback to occur. Independent audits of AWI's Breech Flystrike program continue by the Australian Veterinary Association (two times per year) and by the Genetic Review (once per year). There is ongoing communications with the global retailers and retailer associations. The WormBoss website was redeveloped by AWI and the Sheep CRC and launched in November 2012 at www.wormboss.com.au. The WormBoss decision support system aims to help woolgrowers maximise the timing and effectiveness of drenching and other worm management practices. The LiceBoss website was redeveloped by AWI and the Sheep CRC and launched in June 2013 at www.liceboss.com.au. The LiceBoss decision support system aims to help woolgrowers control lice more effectively, minimise pesticide residues and reduce the cost of lice control. The WormBoss and LiceBoss websites are aligned with the FlyBoss website to deliver an integrated suite of decision support tools, hosted by the Sheep CRC, for woolgrowers to control parasites in their flocks. A project is under way to further integrate the current WormBoss, LiceBoss and FlyBoss tools to reduce duplication and improve efficiencies. Monthly wool residue surveys were funded and undertaken. As part of the Weanersafe project, a drench resistance testing survey and time-based rotational grazing trials have been completed on properties across different rainfall zones of southern Queensland to help develop region-specific rotational grazing recommendations. Focus farms and groups have been established in NSW and South Australia to help ensure "woolgrower ownership" of the eradication of sheep lice, especially a younger generation of farmers who have not previously been exposed to such learning and engagement processes.
