Because cows have consumed a lot of nutrients in the late pregnancy, they are physiologically ill after delivery, which is characterized by breast edema in the first few days after delivery, and the function of the breast and blood circulation system is abnormal. If the farmers want to make money and do not care about the health of the cows, they will not give the cows a chance to recover their body. Instead, they will transfer the cow's blood calcium into the milk, causing the cows to lose calcium and cause postpartum sputum or ketone. Urinary diseases, etc., can also cause cows to die. The scientific method is to strictly control the milking amount, reduce the number of milking, and supply high energy, palatability of forage, feed and sufficient drinking water (preferably warm water) to enhance the cow's constitution within five days after calving. Improve the purpose of total milk production in the future. The specific method is as follows: on the first day after the cows are born, the milking amount can be controlled to satisfy the calf drinking; the next day, the milking amount is controlled at about one-half of the daily milk yield; the third day, the milking amount Controlling about two-thirds of the daily milk production; on the fourth day, the milking amount is controlled at about three-quarters of the daily milk production; on the fifth day, if the cow's physical recovery is better and the appetite is normal, it can be The milk produced is completely extruded. This method can be extended for a few days if the cow's physique is not well restored. YT-H008 YT-H008 Shenzhen Sunshine Technology Co.,Ltd , https://www.yatwin.com
