First, keep proper temperature. The critical temperature for dairy cows to produce milk is 22°C. It is very difficult to reach this temperature in the early spring, except for keeping cows in a greenhouse. At the very least, the temperature should be kept at 13°C. Second, ensure comprehensive nutrition. In the spring, on the basis of feeding cows with hay or silage, the nutritional level of dairy cows should also be appropriately increased. Reference feed formula: cornmeal 60%, soybean cake 20%, bran 10%, fat 3%, salt 1.5%, bone meal 2%, baking soda 1.5%, promote milk premix 2%. If there is no green feed, 5-7 kg of chopped carrots, potatoes, or fresh cabbage leaves should be fed daily. On the basis of the normal milk production of dairy cows, the dairy cows should be fed 1.5 to 2 kg of mixed concentrates for every 4 kg of milk produced. Third, supply plenty of warm water. If the cow is fed cold water in the spring, it will cause the cow to consume a lot of body heat and reduce milk production; insufficient drinking water will also cause some diseases in the cow. Therefore, it should be noted that the spring supply of milk accounts for a sufficient amount of warm water of about 18°C. Fourth, keep the sanitation and hygiene. Dry dairy cows are conducive to insulation. Therefore, the cowshed must be cushioned, dug hay, remove excrement in time, and often sprinkle lime powder or ash in the house. This will not only reduce the humidity in the dairy house, but also prevent and cure the disease. Fifth, adhere to the sun movement. In fine weather, the cows should be allowed to exercise for at least 2 hours every day, and then they should be led to the sun in a sunny place to strengthen the cow's blood circulation, kill the parasitic bacteria in the cows, help and promote the digestion of cows, and improve the quality of dairy cows.
