Autumn is the peak period of cattle breeding. In the severe winter season when the grass is withered, pregnant cows need not only cold attacks, but also all the nutrients needed for the growth and development of the fetus. In adverse climate conditions, if pregnant cattle are improperly reared, especially if they experience abrupt changes in temperature, they may easily lead to a decline in the constitution of pregnant cows during hunger and cold stress, and even result in the death of the mother. For this reason, the following measures should be taken for pregnant cows. 1. Renovate the barracks and keep warm and warm. Pregnant cows should have a separate barracks to avoid crowding and kicking and causing miscarriage. The barns should plug the loopholes, shelter from the wind, do not leak rain, and do not wet. The bedding is often replaced. On a sunny noon, the cows are allowed to go outside and enjoy the sun. 2, to strengthen nutrition, carefully feeding cows after pregnancy, in addition to maintaining their own needs of nutrition, but also need to provide nutrients for fetal growth and development needs, but also accumulate a certain amount of nutrients to ensure lactation. Therefore, 1-2 kilograms of concentrate should be fed daily. Conditional feeding of mixed concentrates is possible. The proportions are: corn 30%, soybean cake 20%, rice 15%, cottonseed cake 15%, rapeseed cake 5%, rice bran 15%, and some bone meal and salt are also added properly. Do regular, quantitative, and less to add ground, do not feed mildew feed. Drinking water should be clean, be careful not to drink empty belly water and ice residue water, it is best to feed warm and hot water. In the absence of rain, it is necessary to insist on cattle grazing up the mountain. Grazing can not only allow cattle to eat green feed, but also increase the amount of exercise, which is beneficial to the health of cattle. Put cattle in the leeward sunny bushes, do not let the pregnant cows eat frost grass. Feed should be diversified, palatable, and digestible. Since winter feeding is generally dominated by coarse materials such as hay and rice straw, attention should be paid to the modulation of feed. It is best to produce ammoniated feed for cattle. This will not only increase palatability, but also increase nutrition. If there is a lack of protein feed during supplemental feeding, urea feed may be used, which can supplement the deficiency of protein. Daily dosage of urea may be 40 g per 100 kg of body weight. 3. Preventing miscarriage and ensuring maternal health Winter feeding and management of pregnant cows are prone to miscarriage. The signs are the vaginal outflow of mucus during the pre-pregnancy period. They constantly look back at the abdomen and become restless; Late pregnancy shows breast enlargement, arching, and repeated use. Urination posture, abdominal pain, fetal movement stopped. Progesterone intramuscular injection 0.5-1g can be used for treatment, once a day, once every 4-6 days, can receive good results. 4. Appropriate exercise and reasonable use of pregnant cows to mid-pregnancy should gradually reduce the intensity of military exercise. In the military service, it is strictly forbidden to draw cold whip, rush to work, turn to sharp bends, and must be cautious, and stop working for one month before labor to avoid causing For miscarriage, pregnant cows who are completely vaccinated and are not enslaved should be drawn to the outside and exercise properly to enhance their physical fitness and prevent dystocia. Mild dystocia can be induced by posterior pituitary hormones. One subcutaneous injection is 60- 100 units. China Agricultural Network Editor
