1. About one month after the ewes are pregnant, the fertilized eggs are easily affected by outside feeding conditions before the colonization of the placenta. Feeding the ewes with spoiled, moldy or toxic feed can easily cause early embryonic death; ewe The dietary nutrition is not comprehensive, lack of protein, vitamins and minerals, etc., may also cause the fertilized egg midway stop development, so ewes early pregnancy - about the month of feeding and management is to ensure the normal growth and development of the fetus is a critical period. At this time the fetus is still small, although the nutrients required by ewe are not high, but they must be relatively comprehensive. Under grazing and captive feeding conditions, in general, the ewes can eat young pastures to satisfy their satiety. Nutrition needs, but in the autumn, winter and early spring, the grassland in the pasture is withered and old, and most farmers use insufficient raw materials such as hay and crop stalks to feed the ewes. Inadequate grazing occurs because the ewes feed on forage nutrition. The limitation of the material is that, even if the ewes grazing and supplementary feeding can reach satiety and cannot meet their nutritional needs, the farmers should properly supplement the concentrates according to the nutritional status of the ewes. 2. After the ewes are pregnant for 2 months, with the increase of the month of pregnancy, the development of the fetus is gradually accelerating, and the amount of supplemental feed should be gradually increased. Soybean 40%, corn 30%, barley 20%, wheat 10% can be used. , soaked in warm water for 6 to 8 hours, grinded into pulp, and then added 10% to 15% soybean cake, 5% to 8% bran, 1% salt, and 3% to 5% bone meal equivalent to the total amount of soybeans, etc. Pregnant sheep supplemented 2 to 3 times, every time each sheep fed 50 to 100 grams of mixed concentrates, young ewes should also increase the amount of fine feed. 3. After the ewes are pregnant for 3 months, the total volume of pregnant sheep fed with forage should be properly controlled. Feeding the forages and adding concentrates to the sheep should be done less frequently to prevent one-time feeding. More oppression of the fetus and affect normal growth and development. 4. After 4 months of gestation, the ewes have reached 60% to 70% of the body weight of the lamb at birth, and the ewes have to accumulate a certain amount of nutrients to prepare for postpartum breastfeeding. 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). Feed, etc., so as to avoid eczema abortion, dystocia and post-production diseases. 5. About 1 month before the ewes are born, the amount of coarse feed should be properly controlled, and feed as soft as possible should be provided, such as nitriding, micro-storage or salted straw, and green and blue succulent feed. Increase the amount of bran feeding to facilitate intestinal convenience. 6, ewes, about 10 days before delivery, should be based on the ewes digestion, appetite, reduce the amount of feed fed. 7, 2 to 3 days before delivery, the ewes have good constitution, large breast swelling and accompanied by abdominal edema, should reduce the amount of feed from the original diet by 1/3 to 1/2 to prevent premature ejaculation. Too much or too milky cause mother breast mastitis, back milk and lamb dyspepsia and diarrhea; for the thinner ewes, if the breasts are dried up for a week before birth, besides reducing the amount of raw material, the amount of hemp should be increased appropriately. Protein-rich prolactin feeds such as cakes, bean cakes, soymilk or bean dregs, and succulent diarrhea feeds to prevent the lack of milk in the ewes. In addition, feed and drinking water for pregnant ewes should always be kept clean.
