First, carefully reared
After the cow is pregnant, it is necessary not only to maintain its own nutritional needs, but also to provide nutrition for the growth and development of the fetus, and also to store a certain amount of nutrients to ensure postpartum lactation. Therefore, 1 to 2 kilograms of concentrate should be fed every day, and good conditions should be used to feed mixed feed: corn, cardamom cake, rice, cottonseed cake, rapeseed cake, rice bran, and salt in proportion. And to ensure that time, quantitative, and less to Tim Tim, never fed mildew degenerate feed, drinking water should be healthy, it is best not to drink water and drink frozen water, in the rain and snow days, insist on cattle cattle grazing, eat grass, improve The amount of exercise is conducive to enhancing the health of the cattle body. Grazing should be selected in the leeward sunny bushes, and the pregnant cows should not be allowed to eat falling frost forage.
Due to the fact that most of the winter season uses hay, straw, and other coarse materials as the main material, it is necessary to do a good job of adjusting the feed. If the ammoniated feed can be used to feed cattle, the palatability of the feed can be enhanced and the nutrients of the feed can be increased. Insufficient, can use urea feed, can make up for lack of protein. The amount of urea used is 40 grams per 100 kilograms of body weight per day.
Second, prevent abortion and protect mother and child health
Late winter pregnant cows, such as feeding and mismanagement, prone to miscarriage, the general signs of vaginal outflow of mucus during the pre-pregnancy, continue to review the abdomen, sit restless, in the late pregnancy showed breast enlargement, arch waist, repeated urination posture, abdominal pain, fetal movement Stop, progesterone intramuscular injection can be used for treatment 0.5 to 1 g, once a day, for 4 to 6 days, can play a good effect.
Third, reasonable service
In the middle of pregnancy, cows should gradually reduce the intensity of military exercise, especially in the military service. It is forbidden to draw cold whips, rush to live, turn sharp corners, and to slow down the service, and stop working for 4 to 5 weeks before labor to prevent miscarriage. For the pregnant cows raised in the pens of the entire family, they will not be encumbered. When the sun is sunny, they must drive the cows to exercise properly, enhance their physical fitness and prevent dystocia. If dystocia occurs, they must be promptly treated.
Long distance LiDAR sensor series are particularly easy to communication thanks to their fixed connector, which can be plugged it up and off by yourself. Voltage is wider from 8v before to 36v. Low power consumption feature makes it beceome a very competitive, high performance-price ratio, long range Laser Distance Sensor.
