Australia's resource for control of worms, flies and lice in sheep, |
This quick quiz tests your knowledge of sheep and goat parasites and their control.
1. Why does drenching in dry weather impose a greater selection pressure for drench-resistant worms than drenching in wet weather?
2. Why do ‘multi-active’ drenches help delay the development of drench resistance?
3. Is it better to treat for flystrike on the same date every year, or to wait and see?
4. When restocking, should you consider that all introduced sheep present a possible risk of introducing lice?
NSW DPI and AWI are still accepting maggots from properties across Australia to test them for resistance to pesticides. These tests are each worth thousands of dollars, but are free during this project. Read how you can submit maggots from your property. >> Read more.
The harshness of the weather on livestock-rearing is evident once again this month. In New South Wales, for instance, in areas that are still without rain, worms are not so much of an issue, but for those who have received the lightest of rainfall, the opportunistic barber’s pole has already killed sheep (see the Bega report).
The message from the district veterinarians is clear. Please seek advice.
