Reproductive performance of an Angus cow after removal of a macerated fetus via caudal flank laparotomy and hysterotomy	2014	6	.pdf	application/pdf	3515	181	49	Keywords: Macrated fetus, hysterotomy, metritis, fertility Background Fetal mummification and maceration have been reported in cattle but the incidence has been described as low and sporadic, with an estimated incidence of mummification between 0.43 and 1.8% of pregnancies.1 In cattle, pregnancy is supported by progesterone produced by the corpus luteum and, after approximately 150 to 200 days of gestation, by the placenta and adrenal glands as well.2,3 Bovine fetal mummification most commonly occurs during the fourth through sixth months of gestation with fetal autolysis, resorption of fetal fluid in a sterile environment and without concomitant loss of the corpus luteum or dilation of the cervix.1,3 Bovine fetal maceration is also associated with a functional corpus luteum but with further autolysis of fetal soft tissues, resulting in only fetal bones remaining in the uterus.3 Fetal maceration is usually accompanied by a partially dilated cervix, fetid vaginal discharge, metritis and often, clinical illness.1,4 Many causes of fetal mummification and maceration have been proposed, including most of those that can cause abortion, such as viral and bacterial infections, genetic factors and developmental abnormalities. In cases of fetal mummification, the dam is usually not clinically ill and seldom shows signs of an interruption of gestation.	cache/ct-11215.pdf	txt/ct-11215.txt
