Equine Dystocia Study Guide

Overview and Clinical Importance

Equine dystocia is defined as any abnormal or difficult labor that prevents natural delivery of the foal. Unlike ruminants where dystocia is relatively common, equine dystocia occurs in only approximately 4% of foalings but represents a true medical emergency requiring immediate intervention. The rapid, explosive nature of equine parturition means that delays of even 10-15 minutes can result in foal death or severe complications for the mare.

The goals of dystocia management are threefold: (1) save the life of the foal, (2) save the life of the mare, and (3) preserve the future fertility of the mare. Early recognition and prompt veterinary intervention are the most critical factors determining foal survival.

Normal Equine Parturition

Normal gestational length in mares is approximately 340 days (range 320-365 days). Understanding the three stages of labor is essential for recognizing when intervention is required.
