was 7.96 1.39 mcg/mL and colostrum was 1.39 0.70 mcg/mL. The DCA concentrations in allantoic and amniotic fluid, placental tissues, and foal plasma were nearly undetectable. These results infer incomplete passage of DCA across fetal mem- branes after administration of ceftiofur sodium to normal pony mares.
