Winter feeding and management techniques for pregnant ewes

First, feed should meet the nutritional needs of the winter to stop the milk production of pregnant sheep, to strengthen the feeding management. 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 kilograms 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. Second, management should not only carefully repair the pens before the winter, but also to achieve "three no, four diligent, one to maintain." "Three Noes" is the pens do not enter the wind, no leakage, no moisture; "four diligence" is the community grazing, diligent grass, ground cleaning, diligent removal of manure; "a" is to maintain the cleanliness of housing 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 should be careful not to go too fast. You must choose a flat place to 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 scare the sheep. Two months after pregnancy, milking should be stopped to ensure that the ewes are healthy and have good fetal development. Third, prevent infectious diseases and miscarriage 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.
