The main causes of abortion in mares in France were studied from 1,822 cases submitted for necropsy. The cause of abortion was established in 74.9 % of cases (n = 1,365). Fetoplacental infections (n = 869) represented 63.7 % of diagnosed abortions. A noninfectious cause was found in 27.2 % of cases (n = 496). Of the infectious causes of abortion, the vast majority were caused by bacteria (n = 695; 79.9 % ), followed by viruses (15.1 % ), and then fungi (1.8 % ). In 27 cases (3.1 % ), no specific pathogenic agent could be identified despite the presence of lesions. Of the noninfectious causes of abortion, umbilical cord abnormalities were the most frequent (n = 300; 60.5 % ). Placental villous hypoplasia represented the second most frequent cause (17.3 % ). This was followed by lethal congenital malformations (6.9 % ). The causes of placental insufficiency other than placental villous hypoplasia—twins, placental edema, placental premature separation, and body pregnancy—were less frequent. The diagnosis of equine abortion cases examined in Normandy seemed to be somewhat in agreement with the findings reported in Kentucky and the United Kingdom. In this study, about 60 % of the cases were associated with a condition involving the allantochorion or the umbilical cord. Thus, to enhance diagnostic success, it is of prime importance to submit the fetal membranes along with the fetus for necropsy.
