Sheepmeat Council : Sheepmeat 2012
SHEEPMEAT COUNCIL OF AUSTRALIA ANNUAL MUSTER 2012 45 oJD update A TFGA chaired, industry wide OJD Taskforce has been set up in Tasmania to agree to a strategic approach for control, eradication and the management and safety of vaccines. The National Sheep Health Statement has been updated and an excellent job is being done by Tasmanian Quality Meats, Cressy, with their State Abattoir Surveillance Program and recently their AHA funded project to look at the costs associated with OJD to the industry, especially to processors. Footrot update This year the TFGA have bought the industry together to develop and seek funding for a Tasmanian Footrot control and eradication strategy. Tasmania is a relatively wet environment and virulent footrot is common in Tasmanian sheep flocks. At least 40% of flocks were found to be infected when a survey was conducted over 10 years ago, with up to 80% of sheep within a flock affected with footrot. Foot-paring and foot bathing programs are only partially effective and very expensive, few contractors are available; good farm labour is scarce; and there is very little residual protection resulting in rapid spread after ewes are placed in lambing paddocks in spring. Eradication has been achieved in very few flocks using conventional techniques mostly due to the short non-transmission period and irrigation practices. Regulatory programs aimed at eradication of virulent Tasmania has seen an increasing proportion of prime lamb and mutton production resulting in a steady increase in meat values. Tasmanian Farmers and Graziers Association footrot were terminated in 1975 and many producers rely on control programs. Regional eradication groups folded after several properties failed to eradicate using conventional techniques. Most Tasmanian sheep producers used FootvaxTM as the basis for effective control and eradication programs and have seen sharp increases of within-flock prevalence since the vaccine became unavailable. Tasmanian sheep producers need ready access to specific and/or multiple strain vaccines, rapid and economical strain typing and accurate up to date technical information in order to overcome the animal welfare and animal production impacts of virulent footrot.
