1, dietary nutrition should be sufficient
In addition to feeding a sufficient amount of grass, silage and appropriate amount of hay, dietary nutrients should be appropriately increased. On the basis of the normal amount of lactation, for every 3 kg of milk produced, 1-1.5 kg of mixed concentrate should be fed to ensure the nutritional needs of the cow. When there is not enough green feed, 3-5 kg ​​of chopped carrots, potatoes or fresh Chinese cabbage must be fed every day.
2, the proportion of feed should be reasonable
In order to meet the nutritional needs of dairy cows, the proportion of concentrate in the diet should not exceed 60%, and crude fiber should not be less than 13%. Generally, the proportion of feed corn, soybean cake and wheat bran is 4:4:2. The ratio of soybean cake should be increased for the cows with good moisture content (because the bean cake is a fat feed, it can be milked); for the thinner cows, the ratio of corn and wheat bran is increased, so that The increase in 膘 (turning lyrics can produce more milk).
3, supply plenty of warm water

5, adhere to the sun sports
In sunny weather, let the cows exercise at least 2 hours a day, so that they are more sun, to strengthen blood circulation, help digestion, increase milk production.
6, carefully brush the body
As the saying goes: “Sharp boring is equal to feeding.†Brushing the body of the cow not only makes the body healthier, reduces the risk of parasites, but also promotes blood circulation and increases milk production. Every day, in the morning and afternoon, it is necessary to brush the cow's body fur once.
7, keep the sanitation
Shelter drying is beneficial to keep warm and must be matted and matted. Timely removal of feces, and often sprinkle some lime powder or ash in the house, this will not only reduce the humidity within the house, but also disinfection and disease prevention, help to increase milk production.
