2. Timely feeding of ewes about one month before the delivery of pregnant ewes, fetal growth is accelerated, and nutritional needs increase. At this time, some compound feeds should be properly supplemented. The formula is corn 50%, bean cake 25%, bran 25%. Each day, pregnant ewes are fed 0.2 to 0.5 kg. The ewes should stop grazing within two weeks after giving birth, feed them, and feed compound feed. Each ewlet feeds 0.6 to 0.8 kg of compound feed daily and can freely feed microfeeds, hay, or bean skins. In addition, we must pay attention to supplement mineral additives, so that the ewes maintain a long milk production peak to meet the growth and development needs of the lamb.
3. Correctly grasping the lamb-raising technique After the lamb is born, the lamb is wiped cleanly around the nose and mouth with a towel to prevent mucus or amniotic fluid from entering the trachea and causing suffocation. If suffocation has occurred, the nostrils or mucus in the mouth should be aspirated as soon as possible and artificial respiration should be performed to revive the lamb. The umbilical cord of the lamb can be broken or manually torn off, and the broken end is sterilized with iodine to prevent infection. If the umbilical cord is bleeding, the sterilized silk thread can be used to stop bleeding.
4. Strengthen the insulation of the lambs' house The cold sheep are short-lived creatures, and the lambing season is in severe winter. Newborn lamb is short in wool, poor in body temperature regulation, and weak in cold resistance. Therefore, it is necessary to strengthen the heat insulation and cold protection of the lamb barn and keep the temperature within 8°C. Lambs raised in the wild during grazing should adopt necessary insulation measures. The grazing staff can put the newborn lamb in a carry-on fur pocket and expose the nose to ensure smooth breathing and prevent suffocation from death. . When the temperature outside the house is above -5°C, the hair-dried lamb should be driven out of the house with the ewes, and the cold exercise should be carried out in the leeward sunny place to gradually enhance the ability to withstand the cold.
5.Lambs feed their lambs in a timely manner 15 to 30 minutes after birth. Mucus that has been covered by body surface has been drained by the ewes, and the colostrum is given as soon as possible within 2 to 3 hours. Before the breastfeeding, the filthy hair around the ewes' udder should be cut off, and after a few drops of colostrum, the lambs should be licked. Frail lambs are to be artificially assisted in breastfeeding. Some primiparous ewes are nervous and avoid licking and refrain from milking the lambs. They are required to artificially consolidate and force breast-feeding. After repeated times, the ewes can normally breast-feed the lambs. In case of ewes breast disease or lack of lactation, the lamb can be fostered or artificially fed. When fostering, ewes with similar lamb age should be selected and their urine or placental coat should be smeared on the lamb. After forced breast-feeding several times, the ewes can be fostered successfully. Artificially feeding lambs can use goat milk, milk or milk powder. The milk temperature should be close to the body temperature of the sheep and it should be fed 4 to 6 times a day.
6. Feeding as early as possible The feeding lamb is born for 3 to 4 weeks. The ewes' milk yield reaches a peak, and gradually decreases afterwards. At this time, the lamb grows fast and needs more nutrients, so feed it as soon as possible. Two weeks after birth, the lambs have behaviors of grasses, and 15 to 20 days should be trained to eat nutritious, good quality and digestible feeds such as fries, carrots, and shredded corn to promote the development of digestive organs and make up for lambs. The lack of nutritional needs. Each lamb is supplemented with 50 grams of concentrate.
7. Attention to disease prevention and control should pay attention to the prevention and treatment of eczema mastitis, white muscle disease, lamb dysentery and other diseases.
Comprehensive measures to improve the survival rate of lambs
1. Reasonably adjust the breeding season for male rams. Before the season of breeding, the male ram must be adjusted once. The ram of the same species with the same purpose and different herds should be used for replacement. Attention should be paid when adjusting the ram to the ewes of the same group. Relationships, the purpose of such adjustment is to prevent inbreeding, so that the unclear inbreeding easily becomes a dominant trait, resulting in lamb deformity, weakness, decreased resistance to disease, viability is not strong.
