If the pregnant sheep does not exceed 24 hours after delivery, pituitrin injection, oxytocin injection or ergotoxine injection 0.8- 1 ml can be used for intramuscular injection at one time.
If the drug method has been used for 48-72 hours and still has no effect, it is advisable to protect the sick sheep first, prepare and disinfect them as usual, and then perform surgery. The operator holds the placenta outside the vulva with one hand and pulls it slightly outward, while the other hand extends into the uterus along the surface of the placenta and gently peels off the placenta. Finally, the uterus is injected with antibiotics or antiseptic disinfectant, such as oxytetracycline 2g, which is dissolved in 100 ml physiological saline or injected with 0.2% Prugni.
The traditional Chinese medicine can be prepared from 9 grams of Angelica sinensis, 6 grams of Atractylodes macrocephala, 9 grams of Leonurus heterophyllus, 6 grams of peach kernel, 6 grams of safflower, 3 grams of Ligusticum chuanxiong and 3 grams of dried tangerine peel, which are ground into fine powder and taken with boiling water. Antibiotics should be injected when the temperature is high.
Extended data:
If not treated in time, it is easy to cause fever due to uterine inflammation, and severe suppurative endometritis will occur, leading to estrus or infertility. The reason why there is not much afterbirth is that pregnant sheep lack exercise, lack of calcium salt and vitamins in feed, unbalanced drinking and feeding, and weak constitution. In addition, metritis and Brucella can also cause diseases, and selenium deficiency in sheep can also cause fetal retention.
Pregnant sheep with placenta retention often show symptoms such as fatigue, loss of appetite or abandonment, poor spirit, lying on the ground, rising body temperature, rapid breathing and pulse. If the placenta can't be retained, it will rot, and the malodorous red rotten lochia will flow from the vulva, mixed with gray and white placenta fragments or blood vessels.
