1. Feeding should meet the nutritional needs. In winter, pregnant sheep that stop milk production should be particularly strengthened. Especially ewes who are immature and pregnant are in need of partial feeding and careful feeding. It is mainly based on high-quality dry feeds, with a small amount of green feed. In the later stages of pregnancy, the fetus needs a large amount of nutrients from the mother. Therefore, it is necessary to gradually increase the amount of concentrates and succulent feeds rich in protein, minerals, and vitamins, which can generally increase 1-2 kg of concentrate. However, the amount of concentrate should be controlled 5 days before lambing. In short, the feeds fed throughout the pregnancy are rich in nutrients and cannot be overweight and easy to digest. Feeding should be timed and quantified. 2. Management must not only carefully repair the pens before the winter, but also “three, four, and oneâ€. "Three Noes" is the enclosure that does not enter the wind, does not leak rain, and does not wet: "Siqin" is a community that is grazing, diligently scavenging, diligently cleaning, and diligently removing manure; "a maintenance" is to keep the shed clean and hygienic. Dry and warm. Absolutely avoid kicking, scaring, and fighting against other sheep or other animals. If there is no snowstorm, proper exercise or grazing should be maintained every day. When you exercise, you must be careful not to go too fast. You must choose a flat place for exercise. Do not go steep slopes and cross the ditch. Should be separated from the ram to prevent strong matches. Do not fight cold whip, so as not to panic sheep. Two months after pregnancy, milking should be stopped to ensure that the ewes are healthy and have good fetal development. 3, prevent infectious diseases and abortion should start from strengthening the body and disease resistance of pregnant sheep, and effectively improve feeding management. Do not feed mildew, acidity, freezing and toxic feed, do not drink cold water and dirty water, but do not drink water on an empty stomach. Sheep feeding troughs should be regularly disinfected, pay attention to changes in the weather, and prevent sudden gale and cold waves from causing pregnant sheep to become ill. Observe the spirit of the pregnant sheep, diet, action and excretion of feces. Observe abnormalities immediately. For pregnant sheep with early abortion symptoms, 10-30 ml of progesterone should be injected once a day until symptoms disappear. China Agricultural Network Editor
