EQUINE EMERGENCY SERIES
THERE are many conditions that can affect a mare while pregnant and around the time of birth (periparturient). Thankfully, the majority will carry their foal to term uneventfully. But what if that is not the case?
To grasp what can go wrong at and around the time of foaling, we must first understand what is “normal”.
