Pregnant ewes

After the ewes are pregnant, they usually show gentle temperament, stable behavior, strong appetite, and easy grooming. Around the first month of pregnancy, the ewes are susceptible to external feeding conditions before the colony is formed. The fed ewes are deteriorating, moldy, or toxic, which can easily lead to early embryonic death; the ewes diet Nutrition is not comprehensive, the lack of protein, vitamins and minerals, etc., may also cause the fertilized egg to stop development in the middle, so the ewes early pregnancy about a month of feeding and management is to ensure that 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.

After 2 months of gestation, the ewes will gradually increase their fetal development as the month of pregnancy increases. Gradually increase the amount of feed supplemented by concentrates. Soybean 40%, corn 30%, barley 20%, and wheat 10% can be used. Soak in warm water for 6~8 hours, grind it into pulp, and add 10%~15% bean cake, 5%~8% bran, 1% salt, 3%~5% bone meal equivalent to the total amount of soybeans, etc. Supplement 2 to 3 times, each time each sheep feed 50 to 100 grams of mixed concentrate, young ewes should also increase the amount of concentrate feed. After 3 months of ewes' pregnancy, the total volume of pregnant sheep fed with forage should be appropriately controlled. Feeding forages and adding concentrates to sheep should be done less frequently to prevent overfeeding. The fetus affects normal growth and development.

After 4 months of gestation, the fetus has reached 60% to 70% of the body weight of the lamb at birth, and the ewes have to store a certain amount of nutrients 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.

About a month before the ewes are born, the amount of coarse feed should be appropriately controlled, and as much as possible, soft feed such as nitriding, micro-storage or salted straw, and green and blue juicy feed should be fed. The bran is added to the concentrate. The amount of feed is beneficial to intestines. About 10 days before the ewe's delivery, the amount of feed should be reduced according to the ewe's digestion and appetite. 2 to 3 days before delivery, the ewes are of good constitution, large breast swelling, and accompanied by abdominal edema. They should reduce the amount of feed from the original diet by 1/3 to 1/2 to prevent premature ejaculation. Or too thick milk causes eruption of ewes, back milk and indigestion of lambs and diarrhea. For lean ewe, if the udder is dried in a week before birth, in addition to reducing the amount of raw material, it is necessary to increase the amount of sesame cake. Beancake, soymilk or bean dregs and other protein-rich prolactin feeds, as well as green juicy diarrhea feed, to prevent postpartum milk shortage. In addition, feed and drinking water for pregnant ewes should always be kept clean.
