The Quick Quiz

This quick quiz tests your knowledge of sheep and goat parasites and their control. 

1.  Why do dual- and multi-active drenches better protect against drench resistance than single-active drenches? 

2. How does tail docking reduce the risk of flystrike in lambs?

3.   If the most important liver fluke drench is given in April when should the second most important liver fluke drench be given and why?

 4.  If lice are found in long wool, how would you determine if a long wool treatment is necessary before shearing?

State Outlooks for August 2019

It remains dry over much of the central and northern areas of NSW and into southern Queensland, but there have been showers in temperate regions. Rain, increasing temperatures coming into spring, and young sheep are three good reasons to monitor stock for worms and coccidia and to develop a fly management plan in the run-up to lamb-marking.

Nematodirus remains a concern in young sheep in areas experiencing continuing dry conditions. In wetter regions, the advice is to have in place a plan to manage the anticipated rise in barber’s pole.

Victoria
>> full report

Close monitoring of worm egg counts and mob health remains important throughout spring as subclinical worm burdens can prevent peak production in at-risk classes of stock.

Queensland
>> full report

Grazing regions are cold and dry, and getting drier. If you are considering a pre-lambing drench, do a worm egg count first.

Western Australia
>> full report

Spring will bring maximum pasture growth and parasites. Monitor lambs as significant reductions in final slaughter weight can occur if moderate worm burdens persist during the growing period. Devise a flystrike management plan ahead of the main risk period.

Tasmania
>> full report

By now there are no finishing lambs, Merino weaners are struggling, and ewes are in the labour ward. Producers are considering if a lambing drench is necessary this year.

South Australia
>> full report

Worm egg counts have been mostly modest, but in the south-east, a third of counts have indicated a need for drenching.
