Dairy cow cooling stroke five measures

In summer and autumn, when the weather is hot and dairy cows are afraid of high temperatures, heat damage or imbalance caused by heat will lead to heat stress. Not only milk production and breeding rate will be significantly reduced, but also the resistance will be weakened and the incidence rate will increase. Therefore, high temperature dairy cows in summer The feeding and management should be based on the cooling of the sun, the specific approach is as follows: Adjust the ambient temperature Dairy sweat glands are not developed, more afraid of heat. When the temperature in the barn exceeds 30°C, it will hinder the distribution of calories on the body surface of the cows and cause metabolic disorders. Therefore, in the summer season, ventilation holes or doors and windows should be opened to promote air circulation and reduce the temperature of the cowhouse. Conditional electric fans and exhaust fans can be installed in the cowshed. When the weather is hot every day after milking in the afternoon, use spray water to cool the body of cattle, increase the appetite of cattle. A pergola should be set up on the sports ground to prevent cows from being exposed to the sun and rain. When it is found that cows have trouble breathing, they can cook the mung bean soup after cooling, and use “wind oil” to wipe the front corners of the cows and the temples on both sides to refresh the body. . Adjustment of diets and reasonable feeding In order to maintain a higher milk yield, the diet composition should be adjusted appropriately to reduce the proportion of crude fiber. In addition to diversification, the diet should be improved in protein levels, and more high quality grass and vegetables should be fed. Green feed such as quails and melons; night grazing, night feeding, etc. are also good ways to prevent heatstroke. Supply of clean drinking water The drinking water of dairy cows is related to outside air temperature, milk production, individuals, breeds, and ages. Generally, lactating cows drink about 100 kilograms of water a day. In addition to drinking water after feeding troughs, free drinking water is set at the sports ground. It plays a good role in mitigating the heat stimuli. At the same time, 0.5% salt can also be placed in drinking water to promote the digestion of cows and ensure that the body's water metabolism is normal. Elimination of mosquitoes and flies, and prevention of poisoning During the summer season, mosquitoes and flies are numerous. Not only do they bite the body of the cow, affecting the cows' rest, resulting in a decrease in the amount of milk produced, but also spreading diseases through mosquitoes and flies. Therefore, screens can be added to the cowshed to prevent mosquitoes and flies from biting the body of the cattle. Trichlorfon 600-800 can also be used to spray the body of cattle to drive off mosquitoes and flies. However, in the use of drugs to prevent excessive concentration and liquid infiltration of milk to prevent poisoning. At the same time, pesticides are used frequently and carelessly during the season. They often cause poisoning in dairy cows. Therefore, care should be taken not to spray pesticides, fertilize farmland, cut green grass, and grazing. Can not be fed with cattle, to prevent poisoning.
