Well dosed lambs with black behinds?

Bleating Lamb

Hi all,
Mid March lambing flock,had lambs in a fortnight ago and all were thriving well (despite the crap weather),all had clean ends at that stage...lambs were dosed with white drench in early May and dosed with Cydectin at end of May.They (and) their Mammies were moved to fresh grass a fortnight ago.
Have noticed maybe 10% of lambs with black dirty ends the last few days.They didn't get them straight after going into the fresh grass.
Will be weaning all lambs this weekend,will give them a cobalt dose,would the dirty tailed lambs benefit from a white drench dose again?.Will be selling most of the lambs in next few weeks so it would prob be an unneeded expense to dose them all.

Thanks for thoughts on best treatment regime for the dirty ended divils.Have mostly Suffolk x and Cheviot x lambs,and it's not just the Suffolk's that are dirty ended.

I'd try them with some copper
As long as there's no texel breeding in them

If you didn't want to use white, the auld yellow dose is cheap as well. Use levifas diamond here. You might be able to get a cheaper brand then that.

Why do you reckon Copper problem?....is black scitters a sign of that?

Copper can help dry up back ends

We alternate between a cobalt and and copper cobalt drench every couple of weeks
I think it's 1 oz copper sulphate in 2L of water and 10 ml each

I was reading somewhere lately about copper and scouring sheep but I can't think where:o

Iirc, if sheep are high in copper, they will have better resistance to worms but if sheep have low copper they will have lower resistance to worms. There was also a mention of copper dosing being used to treat worms back in the day.

I'll have a better look in the next few days hopefully.

Thanks,so has the 'copper cobalt' drench just trace element of copper in it.Is it a shop bought one or do you make up your own mix?
Where would you buy 'copper sulphate?

Thanks again.

Was convinced Mine were lacking in copper a few years back. Until one died and I got postmortem done. Results showed copper levels perfect , but very high worm burden. Just turned out that had a big hatching from very humid weather a few weeks beforehand. So you never know really.

The father was on about that here one day that bluestone was the only dose they had years ago and it was pretty good back then

The lambs haven't been dosed since early May, I think you should get a worm count done. The humid year has lead to a higher worm hatch this year.

We've the same problem with lambs on nice aftergrass. Dad was saying nitogen from the fertilizer scours lambs

Also very important to remember that there is no corolation between dag score (****ty arse) and the fecal egg count in lambs so some lambs are just predisposed to having dirty backends while the worm burden or dosing regieme may not be the issue
