In order to improve the milk yield of dairy cows, it is indispensable to manage dairy cows at night.

1. Appropriate amount of night food: cows are ruminants with large food intake and fast digestion. In addition to feeding enough forage during the day, they should also be fed appropriate amount of forage at about 10:00 at night, but not too much, so as to avoid indigestion, and then let cows drink enough water. Drinking water should be warm in winter and cool in summer. This can not only meet the consumption needs of dairy cows, but also enhance the stress resistance of dairy cows and increase milk production.

2. Brush the cow body at about 10:00 every night: before milking, brush the cow body carefully from top to bottom, from front to back, which can not only keep the fur clean and bright, but also promote blood circulation, regulate body temperature, make the cow comfortable overnight and increase milk yield.

3. Prolonging the light time: lighting with white fluorescent lamp, the light can be prolonged from 9 hours to 13 hours, which can improve the feed utilization rate and milk yield of cows.

4. Keep quiet at night: cows like to be quiet, especially at night, for fear of disturbance. If frightened at night, the milk yield decreases and the acidity of milk increases.

5. Pay attention to the cold and warm at night: the most suitable environmental temperature for dairy cows is 8 ℃ ~ 21 ℃. At night in winter, prevent cold and keep warm; in summer, prevent heat and cool down.

6. Strengthen breast massage: many dairy farms have the habit of milking at night. If you insist on massaging the cow's breasts with warm water before milking, the milk yield can be increased by about 10%.

7, to sleep mattress: cows lie down for a long time at night, such as let cows lie down all night on the wet and hard ground, affecting milk production, but also easy to lead to some diseases. Therefore, after milking every night, the barn should be cleaned and then covered with soft grass where the cow lies, so that the cow can sleep comfortably in a clean and dry environment.

8. Increase nocturnal activities: if possible, drive the cow outdoors for about 1 hour at 12:00 at night, but do not go out in bad weather, which can improve cow digestion, increase appetite and increase milk yield.

9. Make a good night observation: most cows are in estrus at night, and cattle farmers should seize this critical moment to check the cow's estrus, rest, breathing, mental state, etc., find problems and deal with them in time, so as not to prolong the empty period of cows and affect milk production.
