With the advent of summer, the rising temperature will directly influence the milk production of dairy farmers. How to raise cows in summer? Experience can be summarized into ten words: drop, fill, wash, increase, add, drink, blow, cover, control, and prevent. Cows are cold and heat-fighting, and the optimum temperature for their growth is 8°C~16°C. Therefore, the cooling of the sun should be used as the central link of the dairy cows in summer. To compensate for the loss of appetite during the day due to the heat of the day, it is best to add more material in the morning and evening to increase the feed intake; at the same time, feed more green feeds (such as carrots, squash, wax gourds, squash, and melons) that are good in palatability and conducive to cooling. Leather, synthetic grass, etc.) It is forbidden to feed moldy and dewy feeds. Try to feed at night.

The relative humidity in the bragging house should be controlled below 80%%. The cowshed windows should be opened frequently to increase air flow. Conditional fans can be equipped with hair, it is best to increase the power of the ventilation fan, change the horizontal ventilation for longitudinal tunnel ventilation, so that the flow of wind through the cattle body increased. After 12 o'clock noon, fresh water sprayed from the well can be sprayed with a high-pressure sprayer and sprayed every 2 to 4 hours depending on the temperature in the house. Generally, the temperature in the house can be reduced by 4°C to 7°C.
