Practice has proved that milk cows with better night management can significantly increase milk production (which can increase milk production by 15% - 25%). Therefore, cattle farmers should actively take measures to improve the milk production of dairy cows. Keeping quiet at night Dairy cows like to be quiet, especially at night, afraid to disturb. So avoid running the machine near the cowshed at night, honking or making a loud call to keep the cows quiet overnight. Increased conditions for the raising of cattle at night, at around 12 o'clock in the evening, the cows can be rushed to the stadium for about one hour (excluding bad weather nights), which can increase the digestive ability of the cows, increase appetite, and increase milk production. The amount of night food is fed in addition to feed the cows during the day. At about 10 o'clock in the evening, appropriate amounts of fodder should also be fed, and then the cows should drink enough clean water or congee. This will ensure that the cows have food in the gastrointestinal tract at night, meeting the needs of physical consumption such as milk production, and greatly increasing milk production. Brush the body at night around 10pm or before milking, brushing the body with a brush, which can not only ensure that the cow's fur is smooth and clean, but also promote blood circulation, regulate body temperature, make the cow comfortable overnight, and thus improve the cow The amount of milk produced. Observe that at night, most cows begin to heat during the night. Keepers should seize the key moment of the night and carefully check and observe the cow's estrus, so as to avoid prolonging the empty period of the cows due to poor inspection, which will affect the milk production. At the same time, we must observe the rest of the cows at night, ruminants, mental status, etc., and find that problems are dealt with promptly to ensure that the cows are healthy and prolific. Concerned about the night's warm and cold cows most suitable for the ambient temperature is generally 8--21 °C, winter should be good at night to keep warm, summer night should be done to prevent heatstroke. Extending the illumination time can be illuminated by white fluorescent lamps at night. The illumination time is extended from 9 to 10 hours to 13 to 14 hours. This will increase the metabolic capacity of dairy cows and increase digestibility and feed utilization. The amount of milk will also increase. China Agricultural Network Editor
