The incidence of dystocia varies among breeds, with Thoroughbreds approximating 4% and draft mares approaching 10%[1,2]. Uncommon as it may be, dystocia is recognized as being one of the true emergencies in equine practice, withpotentially fatal consequences for both the foal and mare. In a study of over 1,200 fetuses and stillborn foals, fetal asphyxia associated with dystocia was identified as one of the leading causes of reproductive loss in the periparturient period .
Inappropriate intervention can easily traumatize the uterus, cervix and vagina such that the mare’s subsequent fertility is markedly reduced .
Most of the veterinary literature relating to equine dystocia is based on the work of Vandeplassche [1,2,5-9]. In the past decade several investigators have expanded our knowledge about this important problem. The purpose of this chapter is to review the most recent publications pertaining to equine obstetrics.
