I'm a little desperate for ideas.... We've lost 4 fawns. Separate moms, separate pens, separate dads so not genetic. Each fawn displays the same symptoms of being alert, eating, vocal, and then starts to have seizures or convulsions. In between seizures their heads are up and they are responsive and act fine. The seizures progress. They flop onto their sides, legs stiffen and their whole body jerks while the head rolls back to one side. They become more and more frequent and the fawns cry and start to have trouble breathing and quickly die. We've never had this happen in any other fawning season. It has been exceptionally rainy but not every fawn afflicted was born in rain. We did move our entire herd but that was supposedly during a point in pregnancy when it was safe to tranquilize. I'm considering a mineral or vitamin deficiency and we're attempting to have the vet that we work with do an autopsy to try to find answers but that will take some time and we are losing babies! Our adults do not seem affected by whatever this is. Any help we could give our vet would be appreciated. He is open to any ideas.we've given BoSe and B complex at the onset of symptoms and dex in one case. The fawns are dying withing 24 -48 hours of birth. I need ideas!
