After 15 days to 20 days after delivery, dairy cows are generally called the early stage of lactation. The quality of feeding and management during this period not only affects the milk production during the whole lactation period, but also has a great influence on the health status and reproductive performance of dairy cows. Improper feeding and management will result in loss of blood after the calving of the cows, weak digestive function, poor disease resistance, and reduced milk production, and will also affect the normal estrus and breeding of dairy cows. Therefore, the management of feeding and management of dairy cows after childbirth will be strengthened. , can restore their physique as soon as possible, early recovery of the uterus, rapid elimination of the edema of the breasts, prevent postpartum warts and other diseases in dairy cows. First, milking quantity: After the calving of dairy cows, the activity of breast secretion increases rapidly. However, due to the deficiency of the postpartum constitution of dairy cows, the body of dairy cows should be mainly restored at this time. Therefore, during the first few days of milking, do not squeeze all the milk. It should be left with some milk. If the milk is completely extruded from 1 day to 4 days after calving, the blood calcium content will rapidly decline and it will easily lead to postpartum spasm. Even if the treatment is timely, the milk production will be greatly affected, if not treated or the disease is serious. , it will lead to the death of the cow. Generally, milking can be performed within 30 minutes to 60 minutes after delivery. On the first day, only about 2 kilograms of calves can be fed at a time to feed calves. On the second day, about 1/3 of the daily milk yield is squeezed. On the third day, they are squeezed 1/2; on the fourth day, they are squeezed 3/4; 5 days can squeeze all the milk in the breast. This will not only help the cows restore their physique as soon as possible, but also prevent postpartum paralysis. Second, the number of milking: After the calving of the cows, the breasts are often edematous, and the mammary glands are active. According to this physiological characteristic, the calves can eat enough colostrum, and the milking times can be appropriately increased. The daily milking is best 4 More than once, in order to quickly reduce the swelling of the breast, before each milking, it is necessary to fully massage and heat the breast for 10 minutes to 20 minutes. 3. Feeding amount: After the cows gave birth, the gastrointestinal function was weak. High-quality hay and a small amount of bran (about 0.5 kg) were fed within 3 days after the calving. The succulent feed was gradually added in the diet for 4 days to 5 days. 4 kg to 5 kg is appropriate, and then gradually increase the amount of feed according to lactation and digestion. After 6 days, 0.5 kg to 1 kg of fine material is added to the diet. After every 2 days to 3 days, 0.5 kg to 1 kg of refined material is added. kg. General dairy cows recover from 15 days to 20 days postpartum, and breast edema disappears. At this time, the diet can increase to the standard amount needed for milk production. Pay attention to the need to gradually increase the feed and change the type of feed, otherwise it may lead to indigestion of the cow, diarrhea, bloating, etc., affecting appetite and milk production. After the calving of dairy cows, attention should be paid to the control of the amount of succulent feeds and concentrates, and in particular, the amount of protein feeds must be controlled. Do not rush to lactation. Try to feed as much hay as possible to maintain the appetite and body condition of the cattle and create a high yield for the future. Favorable conditions. For individual dairy cows with weak constitutions and weak appetite, they should be fed with Jianwei San every day. After a few days, the cows can restore their appetite. Some dairy cows do not have postpartum breast edema, good health, strong appetite, can feed the right amount of concentrate and juicy feed, 6 days to 7 days to reach the standard amount of feed. Note that the number of cows fed should be consistent with the number of milkings. IV. Drinking Water: When cows give birth, they consume a lot of physical strength, have more water loss, and are thirsty after giving birth, but they cannot supply cold water immediately. Due to the weakness of postpartum dairy cows, drinking cold water is prone to colds and retention of the placenta in the womb. Therefore, after the cows rest for 20 minutes to 50 minutes, they should be given warm bran salt water with similar body temperature, and even drink for 5 days to 7 days. After two weeks, the cows that have not yet been detoxified are fed with Yimu Decoction, and there is a formula for accelerating the discharge of detoxification benefits. The mother soup is prepared by adding 0.5 kg of motherwort. 5 kg water tortoises, served once every 2 days, and even served 3 times, you can receive good results.
