Lambs have poor adaptability, weak resistance, and carelessness in feeding and management will cause death. Therefore, scientific feeding and management measures must be taken. 1. Do a good job feeding lactating ewes. Lambs from birth to 2 months of age rely mainly on breast milk, so supplementation of ewes has a lot to do with the growth of lambs. Supplementary feeding is mainly performed in late pregnancy and lactation. About 4 months, each ewlet is generally fed with 2 kg of high quality hay, 1.5 kg of silage, and 0.5 kg of concentrated feed each day. If the ewes are in good condition, they can use less or no concentrate, and only feed high quality hay. 2. Do a good job of disinfection. In the ewes 7-10 days before birth, the sheds and surrounding areas are cleaned and decontaminated with 10%-20% lime water or 2%-3% solution of risol. Cut off the filthy hair around the udder of the antenatal ewes, then wash the udders with warm water and disinfect with 0.1% potassium permanganate. During the breeding period, the delivery room and the lamb room are cleaned daily and disinfected regularly. 3. Carefully manage. Newborn lambs have poor body temperature regulation, so conditions must be good. For the first few days of the lamb’s birth, the shepherd’s temperature was maintained at about 10°C and should not be lower than 5°C after 10 days. The sheep house should be kept dry and sanitary, with good phoenix, relative humidity of 65%, and avoid to cross the phoenix. 4. Eat colostrum. After the lamb is born, you must eat colostrum in time. Colostrum, commonly known as "gel milk," is the milk secreted by the ewes within 1 week after delivery, and is the best tonic for lambs. The sooner a lamb eats, the more robust it is. Colostrum is equivalent to a lamb's safe drug. It contains the antibodies, enzymes and hormones needed for the newborn lamb. In addition, colostrum has a laxative effect, which can promote the excretion of lamb fetus and increase the resistance of the lamb to disease. 5. Turn the feed off. After the lamb is born, besides eating enough breast milk, it is also necessary to give a supplement as soon as possible. Starting early can improve the gastrointestinal development of the lamb, so that the digestive function as soon as possible to improve, increase appetite, increase feed intake, enhance the body of the lamb, speed up the growth and development, increase the survival rate of the lamb. When the lamb is born 10 to 15 days old, it can train forage. Choose high-quality hay and tie it into a 5-cm-diameter piece of grass and hang it around the beams and walls to allow them to feed freely. After supplementing the concentrate, corn kernels and soybean granules can be fried and crushed into noodles, mixed with a little carrot shreds, salt, and bone meal, and any lamb in the trough can be eaten. The amount of supplemental ingredients increases with the lamb's age. . There must be a sink in the lamb's house, often brushing and changing water, keeping it clean. Set up a salt tank in the house to allow the lamb to feed freely. 6. Grasp the weaning off. Normally developing lambs can be weaned 3 to 4 months of age. This will not only improve the ability of the lamb to live independently, but also help the ewes increase their fertility and rejuvenation, thus creating conditions for the breeding of mandarin ducks. Lambs that are large and well-developed can be weaned first. For small, thin lambs, extend breastfeeding dates as appropriate. After weaning, the lambs are kept in the original circle and the ewes are rushed to the farther sheep homes to avoid lambs and affect the feeding. Lambs should be reared and grazing after weaning to meet the nutritional needs of lambs. 7. Lamb disease prevention and control. This is one of the keys to improving the survival rate of lambs. The disease of the lamb should be mainly prevention. Sheep homes should be kept clean, dry, hygienic and well-ventilated. They should be warm in winter and cool in summer, and should be given regular vaccination and deworming. Once the lamb is found to be sick, it must be immediately isolated and promptly treated.
