We had put a batch of 56 ewe lambs to the ram end of October when they were scanned there was 12 empty so wasn’t concerned about that! But have 14 lambed now and went threw them the other day and 22 have no sign of being in lamb they seem to be the ones that we’re tipped first! They were all vaccinated for enzo and toxo have been speaking to the vet and he says it sounds like enzo but is coming to take bloods tomorrow. Anybody else had this issue! Vet said it’s possible that they have got enzo before they were vaccinated?
