Ewes giving birth to lambs
Childbirth signs
Before ejaculation, some organs of the organism undergo significant changes in histology, and the systemic behavior of the ewe is different from usual. These changes are physiological preparations to meet the needs of the fetus and the needs of newborn lambs. Comprehensive observation of these changes can often predict the delivery time so as to prepare for midwifery.
Change of the breast The breast develops rapidly before delivery, and the gland is abundant. When the child is near the childbirth, a small amount of clear gum liquid can be squeezed out of the nipple, or a small amount of colostrum can be used to increase the thickening of the nipple.
As the vulva changes near the birth, the labia gradually becomes softer, swollen, enlarged, and the wrinkled walls of the labia are unfolded and the skin turns red. Vaginal mucous membranes are flushed, mucus changes from thick to thin and smooth, and frequent urination.
Changes in the pelvic bone The pelvic bones of the pubic symphysis, the iliac joints, and the ligaments on both sides of the pelvic bone have increased mobility. They are soft in the tail and both sides. Holding the tail and root in your hands to do activities up and down, you feel that the sacrum has moved up.
Changes in behavior The ewe’s nervousness, loss of appetite, retrospection of the abdomen, lying up from time to time, constant censure and buzzing, marked subsidence of the abdomen are typical signs of labor and should be sent immediately to the delivery room.
Normal production
When ewes are lambs, it is best to let them produce themselves. The main task of the confinement workers is to monitor childbirth and care for the lambs that are born. During the normal confinement, first cut the flesh around the udder of the laboring ewes and on the inside of the hindlimbs, then wash the breasts with lukewarm water; extrude a few drops of colostrum, then wash the tail, genitals, and anus of the ewes, using 1% Su children disinfection. Under normal circumstances, lambs produce faster than the first born ewes, and the amniotic membrane ruptures for several minutes to 30 minutes. The normal lamb is usually the first two forelimbs first, the head attached to the two forelimbs above, with the hen's blame, the lamb can produce naturally. When two lambs are produced, they are about 10-20 minutes apart, with longer intervals. When the ewes produce the first lamb, they still have responsibilities and show pain. They are signs of twin lambs. At this time, the production personnel must carefully observe and carefully inspect. After the lamb is born, first wipe the mucus of the lamb's mouth, nose, and ear bones to avoid swallowing the amniotic fluid and cause asphyxiation or foreign body pneumonia. The mucus on the lamb, when the confinement worker wipes, must also dry the ewes so as to promote the blood circulation of the newborn lamb and help the ewes recognize the lambs.
After the lambs are born, they usually cut the umbilical cord by themselves. At this time, they can be sterilized with 5% iodine solution at the tear site. If the lamb can't tear the umbilical cord by himself, first flush the blood in the umbilical cord several times to the umbilicus of the lamb, and manually tear it off at an appropriate point 3-4 cm away from the lamb's abdomen for disinfection. About 1 hour after delivery of the ewes, the placenta will be naturally discharged, and the placenta should be removed in time to prevent the ewes from swallowing and developing bad habits. If fetal munitions are not discharged after 2-3 hours after delivery, measures should be taken promptly.
