PARABOSS: BEST PRACTICE ADVICE FOR MANAGING SHEEP PARASITES ParaBoss is a suite of three products – LiceBoss, WormBoss and FlyBoss – developed to help sheep producers in the management of lice, worms and blowflies. The LiceBoss, WormBoss and FlyBoss websites are sources of detailed management information and regional programs that will assist in managing the major parasite risks for sheep. The websites have been developed by expert panels of parasitologists and veterinarians from across Australia. ParaBoss provides access to the three websites at www.paraboss.com.au. Subscribe to ParaBoss News, the twice monthly free email newsletter with state outlooks on the current state of sheep parasites as well as feature articles and the quick quiz to test your knowledge of sheep parasites. You can subscribe on the ParaBoss website. Join us on Facebook at www.facebook. com/paraboss.com.au to see weekly posts on flystrike, lice and worm control. ParaBoss is funded by AWI and MLA and coordinated by the University of New England with industry oversight.

When determining whether a tactical drench is required, a bulk collection will generally give a better estimate of the true mob average WEC when enough (20–40) animals from the mob are sampled. It will not display the variation in WEC among animals, but this is rarely an issue for monitor tests. TESTING When individual samples arrive at your chosen laboratory, they may test each sample separately, or for a monitor test, they may mix some of the individuals together, for example, ten individual samples may be made into two bulk lots of five, with a worm egg count on each bulk. When they receive a bulk sample they will thoroughly mix it and take a number of subsamples; again, the number done will depend on the particular laboratory. Do not put pellets from a number of individual sheep into any one of the small sample bottles in a kit hoping that this constitutes a bulk sample. The laboratory will assume each bottle is from an individual sheep and will not mix the contents; they will take about two grams (the first few pellets) from the top. SUMMARY The more animals sampled for a mob test, the closer the result will be to the true average of the mob; this is the best option for monitor WormTests. Stick to individual samples for DrenchTests, DrenchChecks and WEC ASBV. MORE INFORMATION www.wormboss.com.au WHAT ARE TACTICAL AND STRATEGIC DRENCHES? Tactical or therapeutic drench: a drench given when sheep are suffering from the effects of worms. Strategic drench: a drench given at a critical time to reduce worm larval contamination of a pasture for the benefit of the whole mob or flock rather than just for the treated animals, and/or a drench given, irrespective of worm egg count, at times when they are expected to be most susceptible to worm infection.
