Hi all

i am just wondering what colour Wormers People are using at the moment.
i have a couple of Wethers (6 months old) that are a bit mucky at the moment i wormed 6 weeks ago with chanerverm 7.5% which is Yellow.
but it hasnt cleared it up

i dont regularly worm and only do as needed

im relitavley new to sheep (4 YEARS) and Worming is something ive never really got my head round.

I suppose its best i get a sample but could it be COCCIDIOSIS although there is no blood in the sample

they have been outside since birth and has only sarted within the last mon or so

advice would be greatly appreciated

Get a sample looked at, cocci doesn’t always have blood in the dung, but it will be loose. It could also be that you gave yellow wormer resistance if it is still worms.

If you suspect wormer resistance, and you have more of that wormer available, you could give them a second dose of it now, and then send a sample for FEC in a few days time. That would firstly tell you if worms are the problem, and would secondly tell you definitively if you have yellow wormer resistance.

Surely you’d need to FEC before worming, and then again after, to see what worms have been killed

^ Ideally of course yes. But in this case, the sheep have already been wormed. If you treat again to get rid of any picked up over the past few weeks and then did an FEC, if any eggs are present, that tells you that you have resistance.

What that doesn't do of course is tell you if you *don't* have resistance, or indeed if there were any worms present in the first place! Do you see what I mean?

Get a FEC done , not all types of worm are killed by each family of wormer ( yellow does not kill type l l winter scour ) to check if your wormer worked it is recommended that you take a FEC 14 days after treatment . It is important you give the correct dose based normally on the heaviest animal in the group with a correctly calibrated dosing gun ( buy a small plastic 100ml measuring cylinder off ebay for a few £ )
