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

Fast Fact: Alpha-gal and burger burps

Alpha-gal is not alpha-male’s nemesis. Rather, it is a sugar found in the meat of all mammals except humans and some primates. So what? Well, sensitivity to alpha-gal is the basis of the increasing problem of red meat intolerance. It seems that you may acquire red meat intolerance after being bitten by one of a number of different ticks, depending on where you live in the world. In Australia, the culprits are the paralysis ticks Ixodes holocyclus and Ixodes australiensis. In Japan, Haemaphysalis longicornis, a tick also found in Australia, has been implicated in sensitivity to red meat. In the U.S. the Lone Star tick, Amblyomma americanum, is the culprit. This sad state of affairs results from minute amounts of the alpha-gal present in tick saliva being injected into the victim’s body, resulting in a hypersensitive state. So, before you bite into your roast lamb burger, first check the shrubbery for ticks.

Feature articles

Just because a site has had more hits than Jeff Fenech

Introduction by Paul Nilon, Nilon Farm Health, Tasmania

Continuing to mine the ParaBoss Conference video presentations, I draw your attention to Sandra Baxendell’s explanation of copper oxide pellets (10:42–13:16) for barber’s pole control. This excellent snippet not only describes the use of copper oxide pellets, but also explains the risk of copper toxicity with over-supplementation. Very importantly, Sandra exposes the risks of social media as a source of “scientific” information. All goat producers should view this, but particularly those with smaller herds who may not have an extensive scientific background in livestock production. >> Read more.

Multi-tasking for better fly control

Introduction by Paul Nilon, Nilon Farm Health, Tasmania

Brian Horton’s flystrike tools have received a deal of coverage in feature articles and state monthly reports. In this video section (3:29–14:22) the great man himself describes how to use the flystrike decision support tools. If you open the video on one computer and the tools on your kid’s unit, you can multitask to examine the efficacy of your current treatment regime, or plan to stop mulesing. This will be easy for the women; men, if you succeed, you should expect to do the wiping up while answering questions about the kid’s homework. >> Read more.

Do you really understand worm control?

Introduction by Paul Nilon, Nilon Farm Health, Tasmania

When clients ask the best time to drench I reply “10 o’clock, after a cup of tea”. The point is that worm control is much more than drenching, and it’s important we understand all aspects so that we can tailor programs to our individual farms and react to changing seasons and enterprise mixes. The video from the ParaBoss Conference is the most complete presentation on worm control and managing resistance I’ve ever heard. It contains a prodigious amount of fundamental information. While you can watch it in one sitting the suggested starting point is Lewis Kahn’s section on preventing worms (9:07–17:24). >> Read more.

“Does it bloody work?” 

Introduction by Paul Nilon, Nilon Farm Health, Tasmania

... asked an agitated client who had failed to eradicate a lice infestation. The answer was “probably not”. Clients often present me with a list of possible products that shows they have done some research. Koala stamps all ’round. However, while drench resistance lights many bulbs, resistance to lice products flies under the radar. The lice and flystrike products tool allows you to bring up all registered products for your scenario. Highlighted in blue in the chemical group column is “view resistance notes.” Click on this and you will have your answer. While worm resistance is a highly personal matter, lice resistance tends to be more regional and even universal. So if the tab highlights the likelihood of resistance avoid the product unless you have other particular circumstances.  >> Read more.
