It's hot in summer, and it's easy to get heatstroke. How to treat organic cow heatstroke?

The temperature has been getting higher and higher in recent days, and the high temperature has come in summer. The incidence of heatstroke in cattle is high every year. Cattle farmers should do a good job in prevention and control.

1. Causes of heatstroke in cattle

First, the ambient temperature is too high, especially the damp heat in the barn or the direct sunlight. Generally, when the ambient temperature exceeds 36℃, cows are in danger of heatstroke.

Second, suddenly high-temperature cattle can't adapt well. Entering the high temperature period, the temperature suddenly rises above 36℃, even 38℃~40℃. In this case, the risk of heatstroke in cattle will be higher.

Thirdly, when the temperature in the cowshed is relatively high, the ventilation in the cowshed is not smooth, and the temperature in the cowshed and the cowshed can not be effectively taken away. In this case, the temperature inside the cowshed may be higher than that outside the cowshed.

Fourth, during the high temperature in summer, cows are not provided with enough clean drinking water, or the water is too hot for cows to drink, which is easy to suffer from heatstroke due to insufficient drinking water.

Fifth, the cows are too crowded, the cowshed area is particularly narrow and crowded, or the transportation and loading are crowded in high temperature weather in summer, and the cows are close together, so the body temperature cannot be released, and heatstroke may occur.

Sixth, when the temperature is relatively high, chasing cattle or other reasons lead to a lot of exercise, which will also lead to heatstroke.

2. Symptoms of heatstroke in cattle

In cattle heatstroke, the symptoms are very obvious. First of all, there will be symptoms such as listlessness, fatigue and lethargy. Then when the body temperature rises to 465,438+0℃ ~ 42℃, touching the cow's skin and ears with your hands will give you a feeling of fever. Then, the sick cow will have a series of symptoms such as mouth opening and tongue spitting, nostril opening, shortness of breath and sweating all over. If some seriously ill cows are not treated in time, bloody bubbles will flow out of their nostrils, and the visible mucosa will flush and congestion, leading to coma, unconsciousness and sudden death.

3. Countermeasures for heatstroke in dairy cows

When cows have symptoms of heatstroke, they should be pulled to a cool and ventilated place in time. If possible, it is best to brag with a cold air blower or air conditioner and wash the head and body of cattle with cold water. You can also use cold water to enema the affected cattle, and you can take a lot of cold salt water. Generally, sick cows with mild symptoms can get better as long as their body temperature drops. For some cows with severe symptoms, blood can be bled intravenously 1000 ml, and then 25% chlorpromazine hydrochloride injection 10~20 ml, glucose sodium chloride injection 1000~2000 ml and sodium camphor sulfonate injection/kloc-0 ~ 20 ml.

4. Prevent heatstroke in cattle

After entering the summer, you must set up a sunshade net at the activity site. If the top of the cowshed is made of materials with poor heat insulation effect such as transparent tiles or single-layer color steel, the top of the cowshed also needs a sunshade net. An electric fan must be installed in the cowshed, and a cooling water curtain or a cooling fan can be installed if conditions permit. Cold water can be used to spray cowshed and cattle during the high temperature period at noon, but it must be well ventilated when spraying to cool down, otherwise the cowshed will form a hot and humid environment. In order to reduce the density of cattle and ensure enough drinking water, it is best to add appropriate amount of electrolysis to drinking water.
