Dairy cows should also prevent "wind and wetness" during summer heatstroke
In summer, when the temperature is high and humid, the appetite of dairy cows declines in this environment, and the immune function weakens, such as poor feeding and management, and diseases are easily caused. For the cows' heatstroke protection, people have always attached great importance to it and adopted various measures such as installing fans, building awnings, using water curtains, rinsing cattle bodies, adjusting feed, etc., in order to improve the housing environment, reduce the body temperature of cattle, and increase milk production. Food intake. However, if these heatstroke prevention measures are used improperly, cows may suffer from "wind" and "wet" diseases.
Wind pathogens affect the carcasses and cause illnesses, which are more common in the spring. However, due to the high temperatures in the summer, people often use electric fans to blow directly to the cow's body to cool the cows, or to keep the cows shady and ventilated outdoors. When the temperature drops at night, if the wind speed of the fan is too large or there are drafts and thief winds in the system, the pathogenic bacteria will easily invade the body and cause disease. Wind evil left in the fur, cows will appear itching, hair removal symptoms; wind evils invade the lungs, cows will appear high fever, chills, cough, runny nose and other symptoms; wind evil invade the meridians, cows will appear limb pain, limp symptoms.
"Wet" is too humid in the environment and more common in the wet season. In summer, it is often rainy, and people often spray cows and spray water to cool them, causing the cowhouse to be wet and the mud inside the cow's lap. If the cows live in this kind of environment for a long time, wet evil will invade the bovine body, causing the cows to have heavy limbs, joint swelling, muscle numbness, abdominal edema, skin eczema, diarrhea, diarrhea and other symptoms. Cold and evil together, the condition is more serious.
Therefore, when the cows are allowed to cool off during the summer heatstroke, measures must be taken to ensure that they do not become too overpowered. Otherwise, cows suffering from "wind" and "wet" diseases will lose out.
