lamb dose not working one one lamb

What doses have you used, how do you kanow the doses aren't working ... did you test the lambs for worms,

Dirty tails doesn't alwys mean they have worms, we'd often test a dirty lamb on it's own and there'd be no worms

We test our own here,

There's three types of wormers, a white dose, a yellow dose and a clear dose, which ones have you used already

whichever of those you have used, try a different one, If a white dose doesn't work there's no point in going with any white dose even from a different maker if you know what I mean. all white doses have the same active ingredient

Dosed my lambs a couple of weeks ago. I put them into a rich field of grass and some got very dirty. Didn’t know was it dose not working, the new grass or a combination of both. Took a pool sample and it came up clean as a whistle for words thankfully.

I also had one lamb that I had isolated as he wasn’t doing. I took a sample from just him. He wasn’t dirty at all, was passing balls of dung, and he showed up with worms.

judging dirty back ends isn’t the best way to judge after that

What are his options there? Would ploughing the farm for a year and getting in new sheep help at all?

that’s some headache. I think I heard them say at the Athenry open day that there is research coming from nz showing if a dose hasn’t been used for a good few years if can start to become effective again. Was only a small glimmer of hope they were saying

What would you quarantine dose with what wrangler?

We don't get any tests from multi species.

An interesting fact,..... dung beetles reduce worm infestation on land but cydectin/ivomec kills the dung beetles when they eat dung from treated sheep.

Doesn’t Clik kill that beetle too, or if not it kills something similar

Worms get immune to the dose

Then when you dose sheep, the dose kills all the worms that aren't immune and the sheep puts out on the pasture 100% live worms that are immune to the dose so gradually the only worms on the land are the worms that are resistant to the dose

Its difficult to convince farmers not to dose 10% of the flock though

Very disappointing to have to wait a fortnight for a result, was it for sheep welfare scheme, we sent away a sample for the sheep welfare scheme ten days ago and haven't the result yet .

Out side of the sheep welfare FECs the results come back in a couple days.

Test itself only takes about half an hour
