I was wondering if there was the possibility of someone helping to shed light on reason's for having a deformed foal. My mare gave birth to a deformed foal, she was 356 days gestation (all previous foals have been born at 330days), mare 100% ok, no infection, cleansed properly. Numerous deformities to one foreleg, top jaw 4inches longer than bottom which had a tooth through in middle of jaw, tail was also "curled" back on itself. Nothing to do with WNV, I am in Europe and have no problem with that. Appreciate any input.

The most common cause of fetal deformities in the equine (which are actually rare when compared to some other species) is environmental teratogens. These may include chemicals, some viruses or radiation. It can be very difficult to pinpoint the cause.
The combined jaw description, limb deformity and prolonged pregnancy does make me wonder about one possibility - congential hypothyroidism - which may be associated with encounter with elevated nitrates or low iodine levels during pregnancy (follow that link for more details, and a search on Google will yield more information too).

I am so sorry for you. It is so hard to lose a foal after a year of anticipation and having one with visible problems makes it that much more tragic. Deepest sympathy.

Jos - for the information and links, much appreciated.
Jan - for your kind words.
Obviously I am now concerned for the other mare due to foal soon. Over all the years my family have been breeding we have never encountered anything like this. Hope never to again.
