The Quick Quiz

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

1. What weather conditions would indicate that Nematodirus (the thin-necked intestinal worm) could be a cause of scouring in young stock?

2.  Would you give a routine pre-kidding drench to does in the WormBoss East Coast Zone if kidding is to be spread out over many months?

3. ‘Shear and treat immediately’ is just one option to control lice on ‘introductions’. This option gives good biosecurity, but it may result in high chemical residues. Name 3 situations when it is the best option.

4. Name two non-chemical flystrike control strategies and describe why they delay the development of insecticide resistance in flies?

State Outlooks for September 2019

Much of inland Queensland and New South Wales are still drought declared. Other regions are doing much better, but rainfall is mostly below the long term annual averages and temperatures are much higher than expected for this time of the year.

A worm egg count will help you make an informed decision about drenching ewes at weaning while they are in the yards.  

>> full report

Weaners and light conditioned ewe mobs will require close monitoring of worm burdens to capitalise on spring pasture.

Much of the state is drought declared. Coastal regions around Brisbane and particularly those along the coast north of the Burdekin that have received patchy rains could find worms in their lambs and kids.

Western Australia

The main focus is on worm control in lambs, and very importantly, the opportunity they provide to test for drench resistance. In wetter areas, weaners and hoggets should receive a first summer drench (ideally onto stubbles) to avoid significant worm burdens later in the summer.

Don’t assume the dry times have sterilised your paddocks. The recent rain may trigger a major worm event in the previously dry areas, so watch all mobs, particularly the lambing ewes as the grass comes away.

Worm egg count monitoring will be critical during October/November to decide if a summer drench is required.
