Many factors predispose the mares to retained placenta including: uterine inertia and fatigue, selenium deficiency, calcium/phosphorus imbalances, abnormal hormonal environment, physical (mechanical) intervention during foaling (i.e. dystocia), fescue toxicosis, placentitis, and advanced age. What happens if mare retains placenta? In mares, the fetal portion of the placenta, or fetal membranes, Read more…
