During the heatstroke, it is necessary to open windows and doors during the summer to promote the circulation of the cattle house and reduce the temperature inside the cow house. Put a arbor in the playground to prevent the cattle from being exposed to the sun and rain. At noon every day, the body of cows can be sprayed with fresh water. If farm cattle are found to have mouth breathing phenomenon, they can be fed with cooled mung bean soup, and they can also wipe their foreheads with calamine to refresh themselves. Drink enough water to supply enough water to the farmer, and put a small amount of salt in the drinking water, allowing them to drink freely. Elimination of mosquitoes and flies can install screen screens on cowshed doors and windows to prevent mosquitoes and flies from entering. It is also possible to use 90% of the trichlorfon 700 times to spray the bovine body to kill mosquitoes and flies, or to spray the dichlormone dilution solution directly on the bovine body to prevent mosquitoes and flies biting. Prevention of poisoning During the middle of summer, pesticides are frequently applied on farmland, and carelessness can cause poisoning of cattle. Therefore, grass fed with cattle must be soaked before feeding. At the same time, care should be taken not to cut grass at the places where pesticides have been applied recently, nor to feed cows with spoilage foods and dregs with long storage time to prevent cattle poisoning. In order to do a good job of sanitation, we must constantly clean the barn, remove the excrement, keep the barn clean, disinfect regularly, and rinse the bed with clean water. Brush the body once a day. Brushing should be done before the cattle are used.
