News briefing： Postpartum endometritis in sheep is an acute inflammation of postpartum endometrium, which often occurs after delivery.

Postpartum endometritis in sheep is an acute inflammation of postpartum endometrium, which often occurs after delivery. It is caused by microorganism invasion due to dystocia, retained placenta, prolapse of uterus, incomplete uterine involution, abortion, and stillbirth remaining in the uterus. For ewes who have ever suffered from brucellosis, salmonellosis and other infectious or parasitic diseases affecting the reproductive tract, due to the reduced resistance or uterine damage after delivery, the chronic inflammation of the underlying uterine mucosa will become acute inflammation.

Symptoms of postpartum endometritis in sheep:

Sick sheep are depressed, their body temperature rises, their appetite is reduced or abandoned, their rumination is weakened or stopped, they are slightly puffing, arching back, and purulent, and they discharge mucus or mucopurulent secretions from the vulva. In severe cases, the secretions are dark red or brown, and have a bad smell, especially when lying down. If not treated in time or treated improperly, it can become chronic, often secondary to pyometra, effusion, adhesion between the uterus and surrounding tissues, salpingitis, etc., resulting in disorder of the estrus, repeated infertility or miscarriage after conception.

Prevention method:

Sterilization shall be strictly carried out during delivery, and the primary disease shall be treated in time.

Treatment:

In order to eliminate inflammation, ampicillin sodium can be injected intramuscularly or intravenously, with a dosage of 2~7 mg per kg body weight of sheep, 1-2 times a day. Polytetracycline can also be injected intravenously, with the dosage of 1-3 mg per kg body weight of sheep, once a day. At the same time, when taking sulfamethoxazole orally, the first dose of sheep per kilogram of body weight is 0.1 g, and the maintenance dose is 0.05 g, 1-2 times a day.

In order to promote uterine contraction and strengthen the uterine defense function, and eliminate the exudates in the uterine cavity, oxytocin (oxytocin) can be injected subcutaneously or intramuscularly, with a dosage of 10-50 international units each time. In order to improve the general condition, enhance the heart activity, promote the contraction and recovery of the uterus, and discharge the exudates in the uterine cavity, calcium can be supplemented. 10% calcium gluconate injection is injected intravenously, with 50-150ml each time.

5% calcium chloride injection can also be used for intravenous injection, 20~100ml each time, but it is not suitable for sheep with extremely weak heart. Generally, the uterus is not flushed, and flushing is prohibited for those with severe systemic symptoms to avoid uterine atony and spread of infection.
