LLM Farm Vets Newsletter June 2019
this month we’re trying to do our bit with the global plastic problem - every little helps. Rob Howe gives us a very in-depth look at why dung beetles are good for farms. Dan Stevenson discusses scab in Ewes News and Steph highlights the benefits of worm egg counts towards combating wormer resistance. We hope you enjoy! And as always, any questions, give us a shout.

failed to respond to injectable clear<br />
wormers. These mites were then<br />
exposed to a clear wormer within the<br />
laboratory along with control samples<br />
of mites that had never been exposed<br />
to any treatment products. Worryingly,<br />
the mites collected from the four farms<br />
showed similar low levels of death<br />
when exposed to the clear wormer<br />
product as the control mites did when<br />
exposed to no product at all. This<br />
suggests that the product had little<br />
effect on the mortality of the mites from<br />
the farm outbreaks. The fact that the<br />
control mites (that had never been<br />
exposed to treatment products before)<br />
nearly all died on exposure to the<br />
product shows that it is still effective<br />
but that resistance had developed<br />
on the four farms as a result of overexposure<br />
to these products in the<br />
past. This was the first demonstration<br />
of resistance to clear products in the<br />
UK and it is likely that this represents<br />
some degree of resistance across all<br />
the clear products.<br />
Whilst this is not great news for the<br />
control of a disease that has serious<br />
economic and welfare consequences<br />
there are several things we can do to<br />
ensure effective Scab management:<br />
• If you don’t have Scab then talk<br />
to us about effective quarantine<br />
treatments and biosecurity to keep<br />
it this way.<br />
• If you suspect Scab then involve us<br />
early to make sure the diagnosis is<br />
correct. This way you will not waste<br />
time and money with ineffective<br />
treatments.<br />
• Dipping provides very effective<br />
treatment and protection for up to<br />
four weeks. There are increasing<br />
numbers of contractors offering<br />
fully licensed, mobile dipping<br />
services making this a realistic<br />
option. All of our clients having<br />
used these services, including<br />
those where clear wormer<br />
resistance has been suspected,<br />
have been very pleased with the<br />
process and results.<br />
Whilst Sheep Scab is on the rise and<br />
resistance to clear wormer products is<br />
here to stay there is much we can do to<br />
keep the disease under control on your<br />
farms. Please give us a ring to arrange<br />
a time to discuss your individual Scab<br />
control plan.<br />
