Australia's resource for control of worms, flies and lice in sheep,
and worms in goats

The Quick Quiz

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

1. Name 2 situations when you would drench sheep without a WormTest.

2. Is it possible to breed for flystrike resistance and still improve productivity?

3. Under what situation is resistance to lice treatments most likely?

4. Name other parasites, other than roundworms, that can cause scouring in goats.

>> Check the answers.

State Outlooks for July 2018

The drought continues to bite in many areas of Queensland and New South Wales. Most sheep have some degree of nutritional stress at this time of the year, and stock in lower than desirable body condition are predisposed to increased effects of worms even when present in relatively low numbers. Coccidiosis in lambs is also a concern on some properties.

New South Wales

Producers are being encouraged to continue worm testing during the ongoing dry conditions as there is an increased risk of larval ingestion when stock are supplementary fed off the ground.

The season has been good and egg counts are steadily rising. Monitor weaners and lambs every 2–3 weeks, and mature sheep every 4–5 weeks.

Submit samples of lice and blowflies from your sheep for resistance testing.

Western Australia

A lower body condition score than “normal” makes sheep especially susceptible to worms.

>> full report

Waterlogged paddocks have increased the threat of black scour worm infestations in merino weaners and pre-lambing ewes.

South Australia

Producers in the south east are well advised to monitor stock to determine the need for a drench. Lambs rarely need a drench at marking, but this year could be the exception.
