The quick quiz

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

1. What is a concern with using a long-acting moxidectin product as a pre-lambing drench (i.e. within a few weeks prior to lambing)?

2. For mulesing or castration or tail docking, what are the differences between “analgesic” and “anaesthetic” pain relief treatments?

3. What are the two major sources of lice introduction?

4. When introducing new goats, how can other people’s drench-resistant worms be kept out of your property?

State Outlooks for September 2017

Spring is dry in much of the country keeping worm burdens low. Advisors warn that any rain will quickly start the worm cycle, as many sheep, even those with low burdens are shedding eggs onto pastures.  South Australia and Victoria report good seasons, but worms are on the increase.

This month, Paul Nilon (Tasmania) and Bill Johnston (Goulburn, NSW) discuss why weaning shouldn’t be delayed when pasture conditions are tight, and Colin Trengove (South Australia) and Kate Sawford (Braidwood, NSW) again illustrate the value of wormtesting individual mobs.  


New South Wales
>> full report

Conditions have generally remained dry across much of NSW and temperatures are on the rise. Ewes and lambs in poor condition are at risk of parasitism by worms, flies and lice if rain falls.

Seasonal conditions in the south west have been fantastic, but now is the time to monitor lambs for worm burdens every 3 weeks and ewes every 5 weeks.

Seasonal conditions are dry, but worms are still active.

Western Australia
>> full report

Worm control will have to be especially good this springtime as sheep in most districts are generally in lighter condition and have less resistance and tolerance to worms.

>> full report

Two things have happened in the last month: ewe egg counts have blown out in the run up to lambing, and egg counts in merino hoggets have gone through the roof.

South Australia
>> full report

Rainfall averages are up and great for production, but there is also an increase in the risk of disease and parasite burdens.
