Abstract

Dystocia in mares, though relatively uncommon, is a life-threatening condition requiring prompt intervention to ensure the survival of both the dam and foal. The present case describes the successful management of dystocia caused by primary uterine inertia in a 3-year-old primiparous mare presented with colic and restlessness. Clinical examination revealed normal fetal disposition but absence of uterine contractions, leading to the diagnosis. Supportive therapy with intravenous fluids and oxytocin infusion successfully induced uterine contractions. Subsequently, a “red bag” presentation due to premature placental separation was observed and managed immediately by rupturing the chorioallantoic membrane and applying gentle traction to deliver the foal. Post-delivery care, including antibiotics, anti-inflammatory drugs, antihistamines, and oxytocin, ensured placental expulsion and recovery of the mare. Follow-up confirmed complete recovery within 8–10 days. This case highlights that early recognition and timely intervention are critical in managing dystocia, particularly when associated with uterine inertia. Appropriate use of oxytocin, considering the mare’s sensitivity and dose-dependent response, plays a key role in successful outcomes.
