We run a small operation where we foal out about a dozen broodmares each year, mostly Arabians and Quarter Horses. Last spring, one of our maiden mares attacked her foal. It was a filly which was born with no problems. For the first couple of days the mare was great; the foal nursed and seemed perfectly normal. All of a sudden on the third day, the mare charged at the filly, picked it up by the neck, and shook it. We were putting hay out into the field bunks and saw the whole thing. The filly whirled right out of the pen, through two rails of the pipe fence. She died on the way to the clinic.

This mare has been bred back. Our vet advised us that this mare might repeat this behavior with her second foal, so we should plan to take the foal away as soon as it’s born. She suggested we try to find a nurse mare. She said bottle feeding a young foal takes a lot of work and that the foal might develop weird behavior. What do you think?
