In order to reduce the postpartum cow's mammary gland activity and take care of the postpartum digestive function of cows, cows should be dominated by high-quality hay for 1-3 days postpartum and supplemented with concentrate. The amount of concentrate can be up to 4 kg per day, and the level of calcium in the diet (from 0.2% of dry matter in the diet to 0.6% of dietary dry matter) and salt content should be appropriately increased. For cows 3-4 days postpartum, if the cow has good appetite, health, normal feces, and disappearance of breast edema, the amount of concentrate, hay, juicy material, and silage can be gradually increased as the amount of milk produced increases. It is advisable to increase the amount of concentrate by 0.5-1 kg per day. The ratio of refined to coarse grain is 47:53.
Cows within one week after delivery should not drink cold water, so as not to cause gastroenteritis, should adhere to drinking warm water, water temperature 37-38 °C, after a week can be reduced to room temperature. In order to promote appetite, drink as much water as possible, but for cows with severe breast edema, the amount of drinking water should be reduced appropriately.
After milking, dairy cows have a rapid increase in their milk production capacity and they have a strong metabolism. As a result, metabolic disorders often cause ketosis and other metabolic diseases. During this period, it is strictly forbidden to give premature milk, so as to avoid a rapid decline in body condition and lead to metabolic disorders. For 15 days or more after birth, the focus of feeding should be based on the principle of prompting the cows to return to health as soon as possible.
