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, careful management. Lambs have poor adaptability, weak resistance, and carelessness in feeding and management will cause death. The ability of body temperature regulation of the newborn lamb is poor, so the housing 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 hygienic, with good ventilation, relative humidity of 65%, and no drafts.
4, eat good colostrum. After the lamb is born, you must eat colostrum in time. Colostrum is the milk secreted by the ewes within 1 week after delivery, and is the best tonic for lambs. The sooner the lamb is, the more robust it is to eat colostrum. 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 enhance the lamb's resistance to disease.
5, good feed off. After the lamb is born, besides eating enough breast milk, supplements should be given as soon as possible. Early feeding can promote 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, the corn kernels and soybean granules can be fried and crushed into noodles, and a little carrot silk, salt, and bone meal can be mixed into the trough to serve as lambs. The amount of supplemental concentrates increases with increasing lamb 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 developed lambs can be weaned after 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, creating conditions for the breeding of mandarin ducks. For large and well-developed lambs, weaning can be done first, and the small and thin lambs can be extended for lactation 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, the prevention and control of the lamb's disease. 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.
