State Outlooks for December 2020

WormTest results have varied across the country, so it's important to test before deciding on your drenching strategy over summer. Consider a larval culture to see if barber's pole worm is present in large numbers. Flystrike is increasingly becoming an issue, so now is the time to consider your management strategy.

Perform a WormTest now to assess worm burdens to help time your ‘summer’ drench. Many of our district vets have noted growing flystrike issues with possible chemical resistance, so make sure to consider your management approach, monitor even after preventative chemical has been applied, and treat flystruck sheep appropriately.

With a lot of feed around this will mean worm and fly numbers will be up, and producers should consider the nutritional value of their feed to avoid deficiencies and aid with immunity. WormTest results indicate many mobs will likely need a drench.

Given the warm and wet forecast, Maxine has some advice on whether to drench following rainfall, or whether to WormTest to get a more complete picture, which will help you select a strategy and a drenching product.

 

Western Australia

The time is right for a first ‘summer’ drench, especially for younger sheep, to limit pasture contamination in the lead-up to autumn. For older sheep, consider delaying a drench or using targeted treatment unless worm egg counts are high.

When weaning, Paul’s advice is to go sooner rather than later, as late weaning runs the risk of contaminating paddocks with worm eggs. If considering a first ‘summer’ drench, make sure it’s as effective as possible.

 

South Australia

Conditions are perfect for worms around the state, with intermittent rainfall and mild temperatures. Monitor worm egg counts and consider a larval culture if counts are high to see if barber’s pole worm is to blame.
