[QUOTE="Lucky_P, post: 1097847, member: 12607"] Many possibilities... IBR, BVD, Lepto, Neospora, high nitrates in the feed/water, Ponderosa pine needles, secondary to Anaplasmosis in the cow, the list goes on and on. We've been diagnosing increasing numbers of Neospora abortions in our service area for the past few years. Had two in my own herd abort at about 7 months, this summer, from Neospora. Prevalence of some causes varies from one area to another; Diagnostic workup, including necropsy and exam of fetus and PLACENTA!!!, and maternal serum give best chance of determining the cause. Maternal serum sample alone may or may not be all that enlightening. Unfortunately, diagnostic workups on abortion/stillbirth cases - particularly if it's just a single, sporadic case - have a fairly low definitive diagnosis rate. I go into them hoping to find the cause, but knowing that in many instances, I'm only going to be able to tell the producer and their vet what DIDN'T cause it. However, when we start seeing multiple animals aborting over a short time frame, the likelihood of determining the cause increases significantly - provided we get the proper samples to test. PLACENTA!, fetus, maternal serum, PLACENTA!, feed/water sample. Did I say placenta? Placenta! [/QUOTE]
