First, about 1 month after the ewes are pregnant, it is a crucial period to ensure the normal growth and development of the fetus. Under grazing and captive rearing conditions, ewes can generally meet their nutritional needs by eating young pastures, but in the autumn, winter, and early spring, most farmers use hay and crop stalks. Insufficient grazing for feeding ewes from raw materials cannot meet their nutritional needs. Farmers should appropriately supplement concentrates according to the nutritional status of ewes. 2. After 2 months of gestation, the fetus develops gradually and it is necessary to gradually increase the feeding amount of the supplementary feed. Soybean 40%, corn 30%, barley 20%, wheat 10%, soaked in warm water 6 to 8 Hours, grind to pulp, add 10% to 15% bean cake, 5% to 8% bran, 1% salt, 3% to 5% bone meal equivalent to the total amount of soybeans, etc. Secondly, each time a sheep feeds 50 to 100 grams of mixed concentrate, young ewes should also increase the amount of concentrate feed appropriately. 3. After the ewes have been pregnant for 3 months, the total volume of pregnant sheep fed with forage should be properly controlled, and feeding the sheep with forage grass and adding concentrate should be done with less feeding. IV. After four months of gestation, the ewes have reached 60% to 70% of the body weight of the lambs at birth, and the ewes have to accumulate a certain amount of nutrients to prepare for postpartum lactation. In this stage, it is usually carried out to feed the fetus, and the feeding amount of the concentrate should be increased to about twice that of the pre-pregnancy period. The forage and feeding concentrates should strive to be fresh, diversified, and tender pastures. Carrots and other green and juicy feed can be fed more. It is forbidden to feed potato, vinasse, and unreprocessed cottonseed cakes or rapeseed cakes, and must not be fed with mildew, cold, or overheating, be too acidic, or be mixed with ergots or poisonous weeds (such as flowers and stamens). Etc.) Feed. 5. About 1 month before the ewes are born, the amount of coarse feed should be properly controlled, and as much feed as possible should be given, such as nitriding, micro-storage or salinized straw, and blue-green succulent feed. Increase the amount of bran feeding to facilitate intestinal convenience. 6. About 10 days before the ewe's delivery, the amount of feed should be reduced. 7, 2 to 3 days before delivery, the ewes are of good constitution, large breast swelling and accompanied by abdominal edema, and should reduce the amount of feed fed from the original diet by 1/3 to 1/2; for relatively thin ewe, if During the first week of breast-feeding, in addition to reducing the amount of raw material, it is also necessary to appropriately increase protein-rich lactation feed such as sesame cake, bean cake, soymilk or bean dregs, and juicy green diarrhea feed to prevent postpartum ewes. Lack of milk.
