In the cold late winter, when the grass is withered, pregnant cows are not only attacked by cold, but also provide all the nutrients needed for the growth and development of the fetus. In the harsh climate, if the pregnant cows are improperly reared and managed, especially if they encounter sudden changes in the climate, It is easy to cause the pregnant cows to have weak constitution and weakened resistance to disease, resulting in miscarriage or dystocia of the pregnant cows. In severe cases, the mothers are killed. Therefore, the care of pregnant cows in addition to repair pens, keep warm and cold, but also should take the following measures: 1, carefully strengthen the feeding. Once the cow is pregnant, it not only needs to maintain its own nutritional needs, but also to provide nutrition for the growth and development of the fetus, while also storing a certain amount of nutrients to ensure postpartum lactation. Therefore, a daily supplement of 1-2 kilograms of fine material should be fed in good condition. The blending ratio should be 30% for corn, 18% for soybean cake, 17% for rice, 14% for cottonseed cake, 5% for rapeseed cake, and rice bran. 13%, bone meal 2%, salt 1%. And to ensure that time, quantitative, less to Tim Tim, never fed mildew feed, drinking water should be healthy, it is best not to drink water and drink frozen water. In the absence of rain and snow, insisting on cattle grazing up the mountain to allow cattle to eat grass, can also increase the amount of exercise, help to enhance the health of cattle. The feed is diversified, palatability is good, and easy to digest. Due to the fact that most of the winter season is dominated by hay, straw and other coarse materials, it is necessary to make a good mix of feeds. If ammoniated feed can be used to feed cattle, it can increase the palatability of cattle and increase their nutritional content. When feeding, such as protein feed, you can use urine mixed feed to compensate for protein deficiency. The amount of urea is 40 grams per 100 kilograms of body weight per day. 2. Prevent miscarriage and protect the health of the mother. Late winter pregnant cows are prone to miscarriage if they are improperly reared.

Progesterone intramuscular injection of 0.5-1 g can be used for treatment once a day for 4-6 days with good results. 3, make the disease reasonable. During the middle period of pregnancy, cows should gradually reduce the intensity of exercise. In particular, in the military service, it is strictly forbidden to draw cold whips, to rush, to turn sharp bends, to slow down, to stop causative service 4 to 5 weeks before labor, to prevent abortion. If a slight dystocia occurs. Can use oxytocin oxytocin, a subcutaneous injection of 60-100 units, but also take ethylene estradiol subcutaneous injection of 10-20 grams, can play a good therapeutic effect.
