So they (Aussies) have worked something out. Was it as simple as a doubling of DM% resulting in a doubling of FEC, or something of that order? As for estimating DM, why not have another rough and ready 1-5 scale as for dagginess, or the 1-12 of the Beaufort scale! Agree that the trend is as...

Do we need to make allowance for this when calculating the FEC? Suppose lamb A, 30%DM dung and lamb B, 60%DM may have identical worm burdens but would you expect to get the same FEC result? How would they vary? Anyone sufficiently anal to have worked it out?

Erratic supplies of Scabivax this winter - Is there any evidence that a pre-lambing vaccine injection for ewes in 2022 might extend to cover a second lambing season?

See GO's advice on the Schmallenberg post, he says vaccinate ( against toxoplasmosis) at least 8 weeks before tupping, the "official" advice is 4 weeks. Is 4 weeks long enough?

Re vaccination: I find advice to vaccinate with Toxovax can be at least 3 weeks before tupping, or 4 weeks but now from GO - 8 weeks is recommended. Are we all using the same vaccine or has the advice been updated?

Are any precautions taken to prevent the importation of the "devastating" NZ lung condition into the UK?

Re : Batch numbers. I had similar set of symptoms as in OP, 2 weeks after Hep injections. Lost 1 ewe but saved next case with 10 ml Alamycin LA, 80 ml calc inj and drenched with molasses solution.Lambs lost but otherwise seems totally fixed. My batch number was H246YA05 exp 5/18, so no...

JHT - What was the batch number of your Heptavac P Plus?

Not me.

Don't think anyone has looked at Clun or Llanwenog for relevant mutations as yet and it may be too late at least in the case of the Llanwenog, litters are now history. Is it possible to say where the mutations came from in the Cambridge without having looked at all the different foundation...

Ile de France. Shearer refused to come back following year.

Is that (undeclared vaccination) why the incidence of Johnes in NZ (70%?) is so high? Does imported stock have to be vaccinated (NZ to UK)?

DNA analysis points to a Norwegian (Viking) origin for the Black Welsh Mountain breed, it's quite distinct from all other Welsh breeds. So, yes, their make up is quite different.

Presume you came alright in the end.

Agree with Sheep. Had the head lifting problem discussed on the old forum, the consensus then was that it was wryneck caused by lack of space/poor position in the womb. That might cover Jerry's case but my cases were like focussed's. Was told later that the head-downers were due to glucose...

For the full story, read the biography "Esme" by Teleri Bevan, especially when the couple meet again in their final years.

I once heard you can make your own supply of vaccine from the orf scabs (from previous outbreak?). Has anyone the details?

Evostick Impact/Contact/Instant? will fix a flexible patch. Will probably be required to fix high heels if you try the above instead.

Used to look after an Ile de France flock with wether lambs finishing on red clover. There was enough oestrogen to develop small udders and milk - makes you wonder what happens to the ram when ewes are tupped on red clover?

But all the lambs wont be black if the British "Jacob", which has been improved with Dorset Horn, does not always have 2 copies of Ed. Would any Jacob breeder comment on the incidence of white Jacobs out of Jacob x Jacob?
