It is strictly forbidden that inbreeding sheep have short production cycles and prone to mixed generation, thereby producing lambs of small size, slow growth, and even deformities (bisexuality, anal locks, dementia, etc.). Therefore, the male ram must be frequently exchanged and supplemented 2 months before its breeding to maintain a good body condition. Keep pregnant ewes in the first 3 months of the ewes' gestation period, the fetus grows slowly, the nutrition needed is not much, the feeding amount can reach the satiety; if the sheep is not full when grazing, it should be filled in time. feed. The last two months of the ewes' gestation period is the stage of fetal rapid weight gain. At this time, the fetus grows and develops very quickly, and 90% of the primary birth weight is completed in this period. During this period, if there is insufficient supply of nutrients, the resulting lambs are small, with few hairs (some of them are just exposed), delayed reflexes, poor physiological function, poor resistance, and easy death from disease. Ewes are also prone to failure during childbirth. Postpartum lactation is reduced. Therefore, strengthening the rearing and management of the pregnant period is important for improving the birth weight of the lamb and promoting sufficient milk for the ewes to ensure the survival of the lamb. Therefore, at this stage, not only the ewes should be fed, but also their needs for protein, minerals, and vitamins should be compensated. Every day, they should feed 1 to 2 kg of good quality hay (forage legumes is better) and 0.2 to 0.5 kg of concentrated feed. . Good management of newborn lambs Lamb lambs have poor ability to regulate body temperature and are very sensitive to changes in outside temperature. Therefore, winter lambs and early spring lambs must be well insulated and protected from cold. After the lamb is born, it is necessary to have the ewes pick up the mucus on the lamb as soon as possible to prevent the lamb from freezing. When winter lambs are produced, the sheep house should be equipped with heating equipment, and the ground should be covered with soft hay and wheat straw to prevent cold insulation. The delivery room temperature is maintained above 10°C. Colostrum is the milk secreted by the ewes 3 to 5 days after delivery. Colostrum contains large amounts of antibodies, proteins, minerals, and vitamins. The colostrum must be eaten 30 to 60 minutes after birth, which plays an important role in strengthening the body, fighting disease, and excreting meconium. The sooner and more colostrum is eaten, the faster the lambs gain weight, the stronger the constitution, and the higher the survival rate. Lambs who have lost ewes, lambs, or ewes after birth have to be fed on behalf of the colostrum. Feeding a nursing lamb from birth to 45 days is the fastest growing period for lambs. At this time, the ewes have high lactation and nutrients, but after that, the amount of lactation begins to drop, and breast milk can no longer meet the nutrition needed for the growth and development of lambs. At this time, it is necessary to supplement the lambs. In general, lambs are trained at 10 days of age to promote forage development and increase the source of nutrition. The method is to bundle young grasses and hang them in the air so that the lambs can eat freely. Training is usually started 15 days after the lamb is born. Concentrate should be nutritionally comprehensive, easy to digest and absorb, and strong palatability. When feeding, add less ground. As the lamb grows, the amount of feed increases gradually. After 2 months of age, the lambs are mainly feeding, require diversification of feed, pay attention to individual development, and make adjustments at any time to promote the normal development of the lamb. Dietary digestible protein is suitable for 16% to 20%, and digestible total nutrients is appropriate for 74%. At this time, the lamb should also be properly exercised. Lamb lambs are usually weaned at 2 months of age. Weaning methods are divided into one-time weaning and batch weaning. In general, we use a one-time weaning process for multi-industries. This method is a strong stimulus to the lambs. To reduce weaning stress, the method of weaning without leaving the circle and not leaving the group is used to drive out the ewes. The lambs are left in the original circle to maintain the original environment and feed, and should be strengthened after weaning. Feeding helps the lamb to pass the weaning pass safely. If the littermates are not well developed, weaning can also be done in batches. Do a good job in environmental sanitation for sheds and regular disinfection. At the same time pay attention to the observation of the lamb's mental state, appetite, feces and other conditions and found that the disease is treated in time.
