Strengthen Drinking Water and Feeding Management Set up free drinking water tanks in sports grounds and rooms, ensure adequate water supply for continuous water supply, and use available low-temperature water, which can not only meet clean drinking water, but also play a good mitigating role in heat stress. At the same time, 0.5% of salt can be placed in drinking water to promote digestion of cattle and ensure the normal metabolism of bovine salt. At the same time, when feeding fodder, pay attention to feed more green and succulent feed that is conducive to cooling, and try to feed at night. Due to the heat of the day, the cow's appetite diminished. Feeding forages and feeds can increase their feed intake, and they must not feed cows with spoilage grass, fruits and bad foods to prevent poisoning.
Note that the cow is afraid of heat, so when the temperature in the cowhouse exceeds 30°C, it will hinder the distribution of heat on the bovine body surface. The cowshed contains a large amount of ammonia. If the long-term concentration is too large, the cow's resistance will be reduced and the incidence rate will rise. high. Therefore, the cowshed must be ventilated, which not only reduces the temperature of the cowshed, but also improves the air quality of the cowshed. In addition, if the cow appears stunned coma, gait instability, spit foam, body tremors, high body temperature symptoms, then cattle may have a heat stroke, this time should immediately lead the cow to a cool, ventilated place, cold salt water irrigation , with 25 °C water boiled whole body or wash your head with cold water, cold water can also be enema.
Good cattle body and sanitation breeders should brush and clean the feeding trough and cattle bed after each cow under the trough, and perform fermentation treatment on the excreted feces in a timely manner, and regularly spray 5% of the excrement into the house. Disinfect and fill the cesspit to avoid the breeding and interference of mosquitoes and flies. Farmers can add screens to the cowshed to prevent mosquitoes and flies from biting the body. For open cow houses, it is very difficult to disperse mosquitoes. Spray the body with 0.1% to 0.5% solution of trichlorfon. When the drug is used, the concentration is too high and the liquid penetrates into the body to prevent poisoning.
