1, cold and cold: pregnant cows have a separate barnage, so as to avoid congestion, kicking abortion. Cowshed requires air circulation, warm and dry, spacious and sanitary. Before the arrival of the cold current, it is necessary to refurbish the cowshed in a timely manner so that no rain or snow will fall on the roof, and the ground will not be wet or damp and the four will not be able to avoid the cold wind. Circles are cleaned and kept dry. At noon on sunny days, cows can be allowed to go outside and enjoy the sun.
2, carefully feeding: After the cow is pregnant, in addition to maintaining their own needs of nutrition, but also need to provide the needs of fetal growth and development, but also store certain nutrients to ensure postpartum lactation. Therefore, one to two kilograms of concentrate should be fed every month. Conditionally, it is necessary to feed mixed concentrates. The proportion of blends is 30 percent for corn, 20 percent for soybean cake and 15 percent for rice. 15 percent of cottonseed cakes, 5 percent of rapeseed cakes and 15 percent of rice bran are fed with urea mixed feed, which can supplement protein deficiencies. The daily dosage of urea can be forty cows per hundred kilograms of body weight. Grams are appropriate.
3, a reasonable service: pregnant cows to mid-pregnancy, should gradually reduce the intensity of military service, there is no enforcing the use of cold whip, rush, turn sharp bends, to be slowly cautious. One month before the onset of labor, the service shall be suspended so as not to cause miscarriage.

Progesterone intramuscular injection of 0.1 g can be used during treatment, once daily injection, and even for four to six days, good results can be obtained.
