Normal delivery:
First cut the wool around the breast of the ewes and the inner side of the hind limbs, then wash the breasts with warm water; squeeze a few drops of colostrum, then wash the ewe's tail root, genital area, anus, use 1% to Su Water disinfection. Normal lambs usually have two forelimbs first, and the head is attached to the two forelimbs. With the responsibilities of the ewes, the lambs can naturally produce. When producing double lambs, the interval is about 10 minutes to 20 minutes, and the individual intervals are longer. When the ewes produce the first lamb, they still have blame and pain, and they are signs of giving birth to the two lambs. After the lamb is born, the umbilical cord is naturally broken. If the umbilical cord is not broken, use a finger to twist from the abdomen 5 cm to 8 cm, and then use 5% iodine to spread on the broken end for disinfection. Do not use scissors or blades to cut the umbilical cord, nor ligature the umbilical cord. One hour after the delivery of the ewes, the placenta will naturally be discharged, and the placenta should be removed in time. If the ewe's placenta has not been discharged within 2 hours to 3 hours after delivery, measures should be taken in time.
Dystocia and dystocia:
Midwifery's midwifery: The amniotic membrane breaks water for 30 minutes. If the ewe is weak and the lamb is still not produced, it should be assisted immediately. If the fetal position is not correct, first send the exposed part of the fetus back to the vagina, raise the hindquarters of the ewe, and enter the birth canal to correct the fetal position, and then pull the fetus with the rhythm of the ewe; if the fetus is too large, The two forelimbs of the lamb were pulled out and fed several times, and then the forelimbs were pulled one by one, and the head was raised with one hand, and the ewe was slowly pulled down with the ewe. Do not use too much force, or do not pull hard according to the rhythm of the blame, so as not to hurt the vagina.
Treatment of fake lambs:
After the lamb is produced, if it does not breathe, but the development is normal, the heart still beats, called a suspended animation. The reason is that the lamb inhales amniotic fluid, or the delivery time is longer, and the uterus is deprived of oxygen.
Approach:
One is to lift the two hind legs of the lamb, and hang the back and the chest from time to time;
The second is to let the lamb lie flat and use both hands to rhythmically push the sides of the chest. After these treatments, the short-lived lambs can recover.

After the lamb is born, the mucus in the mouth, nose and ears of the lamb is removed and wiped clean. The mucus on the lamb, while the manufacturer is wiping, also let the ewes dry. Lambs should be eaten as soon as possible within 2 hours to 4 hours. In addition, artificial feeding of the weaker lambs should be carried out in time. At the same time, pre-immunization is carried out, and 1500 units of tetanus antitoxin are injected into the newborn lamb to prevent tetanus in the newborn lamb.

The lactation of the ewes can be carried out by the following methods to ensure sufficient milk. 1 kelp 25 grams, 100 grams of lard, put the soup in the pot, let the ewes eat at a time, generally about half a day after feeding, the milk production increased significantly. I will feed it once every 3 days to 4 days, and then feed it 3 times to 4 times, and supply enough green and juicy feed. 2 250 grams of soybeans, swell in water, then refining and cooking, let the ewes drink themselves after cooling, twice a day for 3 days to 4 days. 3 250 grams of honey, two eggs, mix and feed the ewe, once a day, for 2 days to 3 days.
