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

Where do you stand on lice biosecurity? 

Introduction by Paul Nilon, Nilon Farm Health, Tasmania

Have you noticed that some producers treat for lice every year? While it’s not easy to keep lice out of your flock, a systematic approach makes a world of difference. Of all sheep diseases, the risk of lice can be managed better than many others. A lice biosecurity plan increases the chance of eradicating lice and keeping them out. 

Essential elements for eradication include:

  • Complete musters.
  • Appropriate chemical, particularly if you have split shearing or treat close to lambing.

To stop introductions consider the following:

  • State of the boundary fence (action according to the risk posed).
  • Neighbours risk: sheep traders versus closed flocks. Merino versus XB—those XB lambs are second only to goats in their capacity to stray; if you are a lamb finisher, give plenty of thought to how you will keep your lambs at home.
  • Your sheep introduction policy: don’t forget the good, old sheep health statement. Avoid saleyards if you can.
  • Sheep to sheep transmission is a higher risk than non-sheep transmissions, such as tufts of wool on fences or shearers moccasins. >> Read more.

When should goats be drenched for barber’s pole?

Introduction by Paul Nilon, Nilon Farm Health, Tasmania

Barber’s pole is a real challenge in goats. Indeed, high-risk barber’s pole regions are problematic for goat production. For small holdings, one strategy is to use the FAMACHA system to assess anaemia. It works brilliantly, but is not applicable to large enterprises because of the labour requirement. This MLA article (and the webinar link at the end) explains how to use FAMACHA results, while visual learners may like this YouTube link. The big advantage of FAMACHA is you only drench animals that need it, rather than the whole mob. Moreover, animals that return consistently high FAMACHA scores can be culled as being less resilient. Always perform FAMACHA with a score-card in hand. >> Read more.
