Beyond the Bale : Apr - May 08
12 BIOSECURITY BEYOND THE BALE CHANGES TO STREAMLINE THE OJO SCHEME WoolProducers Australia, in conjunction with other stakeholders including AWl, has developed a new five-year program to manage ovine Johne's disease (OJD), while continuing a risk-based trading system for producers.The main features of the program include the continuation of: o the Assurance Based Credit (ABC) scheme; o abattoir surveillance to estimate regional Prevalence Areas and for the early detection of infection in Low Prevalence Areas; o vaccination; and o the use of the Sheep Health Statement to enable prospective purchasers to manage the risk of inadvertently introducing the disease. The industry will continue to fund abattoir monitoring with surveillance now to be undertaken by the Australian Quarantine and Inspection Service (AQIS). The major differences in the new national program are the number of Prevalence Areas and their associated ABC points. The changes are designed to streamline the program and make it simpler to trade sheep. The data collected at abattoirs in the past six years has provided important information to individual producers, state and national industry groups, and governments about the animal health status of the Australian flock and the regional prevalence of Johne's disease. As a result of this information, the Prevalence Areas have been reduced from four to three with new boundaries that more closely relate to regional risk. The points allocated to each of these new Prevalence Areas have also changed and better quantify the risk that sheep from these areas represent. The changes to the ABC scheme were introduced on 3 I March. WoolProducers Australia has also jointly funded, with Meat and Livestock Australia, research into OJD at the University of Sydney's Faculty ofYeterinary Science at Camden, which will hopefully lead to better tools for the diagnosis and control of OJD in Australia. At the farm level, the researchers have identified risk factors that are associated with the range of different rates at which OJD occurs in infected sheep flocks. Both management and soil factors affect OJD prevalence. The level of pasture contamination, management and nutrition of young sheep, and infected dams appear to be the major drivers for OJD infection. Sheep raised on soils containing a higher percentage of organic carbon are also at greater risk. From the producer's perspective, the disease prevalence could be reduced by: o reducing stocking rates, particularly in the lambing paddock; o improving nutritional status of ewes at lambing; OJD Prevalence Area for implementation from 31 March 2008 OJD Prevalence Areas _ 0 High Prevalence _ 2 Medium Prevalence _ 4 Low Prevalence King Island o OFlinders v;llsland 2 Tasmania Source NSW Department of Primary Industries o providing superior nutrition to weaners; o vaccinating sheep with the Gudair@ vaccine; and o improving farm biosecurity.
