How to Keep Dairy Cows in Summer and High Temperature Season

In summer and autumn, when the weather is hot, cows are prone to heat stress, affect normal milk production and reproduction rates, and can also reduce the cow's resistance and increase the incidence rate. Therefore, taking a variety of measures to prevent heatstroke is the key to raising dairy cows in summer and autumn. Improve the environment Microclimate When the temperature in the dairy house exceeds 30°C, it will affect the heat dissipation on the surface of the house and the metabolism will be hindered. Therefore, in summer and autumn, all the vents in the cowshed should be opened. Ventilation by doors and windows cannot be performed. Conditional fans or exhaust fans should be installed to increase the air circulation to reduce the temperature of the barn and to eliminate the foul gas in the house. After milking in the afternoon, it is also possible to cool the bovine body surface spray directly. Adjusting the structure of the diet In order to maintain a higher milk yield for dairy cows, it is necessary to appropriately adjust the structure of the diet to reduce the proportion of crude fiber. In addition to diversification, the type of concentrate diet should increase protein levels, and feed more green grass such as high quality grass and vegetables. . Feeding time, such as early morning feeding, late night feeding, and evening grazing, can also increase the intake of dairy cows. Supply of sufficient drinking water Milking cows typically consume no less than 100 kilograms per day. Water should be added to the sink and enough sinks should be installed on the sports ground to ensure uninterrupted drinking of cool water. In order to promote the digestion of cows and ensure the balance of water and salt metabolism, 0.5% salt can be added to drinking water. Do a good job of cleaning the barn, remove the manure promptly, and scour the ground with clean water. Do not allow the manure to ferment in the cowhouse. By strengthening the ventilation and ventilation, it is ensured that the harmful gases such as ammonia gas and carbon dioxide within the house do not exceed the standards, no odor, dry, cool, and the environment is regularly disinfected. Killing mosquitoes, flies and flies will not only bite the cattle, affect rest, and reduce the amount of milk produced, but it may also spread diseases. Therefore, screens can be installed on the barn, and 90% of trichlorfon 600-800 times the body sprayed with cattle, to kill mosquitoes and flies. However, it should be noted that the concentration of the drug should not be too high, there can be no odor, can not penetrate into the milk.
