The ewe arrived at the due date and showed signs of delivery, showing signs of unease, waking up and lying down, constantly moaning, and a large amount of amniotic fluid flowing out of the vagina, constantly angry and blaming, but the fetus was never seen. Through a combination of animal ultrasound and manual examination, it was found that the cervix of the sheep was tense and narrow, only able to accommodate one finger, and could reach the forelimbs of the fetus. Due to incomplete cervical dilation and amniotic fluid rupture, a cesarean section was performed after observation with B-ultrasound in animals.

After cutting open the selected incision on the ewe, tear the fetal membrane by hand and release amniotic fluid. Then hold the fetal forelimbs and carefully remove the fetus. After removing the first fetus, follow the same steps to remove the other two fetuses from the two uterine horns. After the fetus is removed, immediately lift it upside down, remove the amniotic fluid from the mouth and nose, gently pat its back, dry its fur, and place it in a thermos for the care of an assistant.

Due to the tight connection between the fetal placenta and the maternal placenta, no shedding was performed, but the placenta near the edges of both sides of the uterine incision was completely shed, otherwise it would hinder uterine suturing. Then rinse the uterine cavity with warm physiological saline and add 1.6 million IU of penicillin powder. The incision is made by continuously suturing the uterine wall serosa and muscle layer with silk thread and round needle. Rinse the uterus with warm physiological saline and then use gastrointestinal suture method to suture the second inversion suture (the needle cannot penetrate the serosa). Return to the uterus, spread 1.6 million IU of penicillin powder into the abdominal cavity, suture the peritoneum and muscles separately using nodule suture method, and finally suture the nodules to the skin. Apply 5% iodine solution after organizing the creative process. After surgery, a Veterinary Ultrasound should be used to observe the recovery of the uterus. It is more beneficial for development.
