birth.30 Foals born prematurely have lower cor- tisol concentrations ( 3 g/dL) within 2 hours post-delivery compared with normal full-term foals (12–14 g/dL).31 In addition, premature foals showed remarkably higher ACTH concentra- tions in comparison with normal full-term foals, 650 pg/mL vs 300 pg/mL 30 minutes post-delivery.
In mares with placentitis, treatment strategies to prevent premature delivery should be instituted, prolonging fetal time in utero to allow greater fetal maturation and improve the possibility of neonatal survival. Conflicting opinions exist as to whether mares suffering with placentitis close to 340 days’ gestation should have parturition in-
