All of my flock were wormed, Heptavac'd and Dectomax'd last week.  However two or three of the lambs have quite severe scours, although they are pinging around, eating properly and not looking ill at all.  Is this just the grass they are on, they have been on it for a while now??  Anything I can do for them?

I would dose them with Bimamix or similar scour-stopper from the vet

I know it is early in the season but you haven't dosed for fluke? I have noted on my travels that there is a lot of stock with dirty tails. The constant cold and wet and the fluctations in temperature can cause scours.

Try worming again 7-10 days after the first dose.  Due to the sudden warm weather / rain combo you can get large hatches of worms in a very short space of time, and you need the extra dose of wormer to get rid of them.

If that doesn't sort it get a FEC done, that will show up fluke too.  And whilst they still have dirty bums watch out for strike.

I to would go for a product to dry them up , in the same way you would take diarrohea relief , gut damage can be slow to heal . You say you wormed the sheep and gave them dectomax so you actually wormed them twice maybe with two different groups ?? the biggest reason for wormers not working is under dosing on weight .  Fluke at this time of year should not be a problem in young lambs . If your grass is growing fast or very wet then lambs will scour .  Do a worm count if the scours don't stop and if worms are present after two wormers then you are in big trouble . Since you say the lambs are happy and the scour is green not grey or black ?? then you can discount cocci

If you are gonna worm, do a FEC first, because a) A FEC is a darn sight cheaper than buying wormer (my vet does it for nothing on sheep) and b) routine worming aids resistant strains of worms.


Try moving the sheep onto poorer pasture if the stuff they are on is too lush (ie they are scouring with no real explanation). Certainly dont be caking them at this time of year.
