Puerperal metritis is the inflammation of uterus from the time of parturition to 2-8 weeks or more in all species. It is not accompanied by septic or general symptoms of illness.

Septic metritis is an acute inflammation of the uterus that occurs within 1–10 days after parturition (giving birth), characterized by the presence of systemic infection signs such as septicaemia (bacteria in the blood), toxaemia (toxins in the blood), and pyaemia (pus-forming bacteria in the blood).

Postpartum uterine infections in animals are bacterial infections that develop in the uterus following parturition.

Total uterine prolapse is a common complication of third stage of labour and more common in pluripara than primipara.

Retention of fetal membranes (RFM) in mares is potentially more serious affection than the same in cattle. In horses, RFM should be treated as an emergency.

Retained fetal membranes (RFM) or retained placenta in cows is defined as the failure of the villi of the fetal cotyledon to detach from the maternal crypts of the caruncles and retained longer than physiological time limits.

Subinvolution of placental sites (SIPS) is a postpartum reproductive disorder primarily seen in bitches, where the placental attachment sites within the uterus fail to properly heal and regress after parturition.

Prolapse of the rectum occasionally occur in any animal in dystocia due to persistent violent straining and a relaxed anal sphincter.
