Causes, symptoms, prevention and treatment of heatstroke in beef cattle

Now the summer temperature is getting higher and higher, and high temperature is a great test for beef cattle, high temperature is very easy to cause the symptoms of heatstroke, serious will lead to dehydration and death of beef cattle, which is very harmful to beef cattle breeding. So what are the causes and symptoms of heat stroke in beef cattle? How to prevent and cure it? Let's take a look at the pro-farm network.

1. Etiological analysis.

When it is hot in summer, if the beef cattle are in a muggy, poorly ventilated environment, coupled with hot and little rain, and there is no shading or shading equipment, the body temperature of beef cattle begins to rise sharply, and there is obvious congestion in the blood vessels on the head and body surface. leading to nervous system disorders. In addition, when there is a lack of drinking water, coupled with a large amount of heat dissipation leading to sweating, to the body loss of a large amount of tissue fluid, it can not be replenished, resulting in poor blood flow, hyperemia and hypoxia.

2. Symptoms

At the beginning of the disease, the sick cattle began to show excitement, constantly sticking out their tongues, breathing vigorously through the mouth, conjunctival congestion and redness, dilated pupils, and a significant increase in body temperature, up to 43 degrees. Head burning, rapid heartbeat, but slow, weak limbs, unstable walking, sometimes falling to the ground, lethargy, dizziness, foaming at the mouth, convulsions, and difficulty breathing. Some sick cattle show extreme agitation, violent phenomena, reduced reflexes to body parts, spasms and, in severe cases, death within hours.

3. Treatment methods

For timely medication after heatstroke, the first thing is to lower the body temperature, first move the sick cattle to a cool area, and if they can't afford to fall to the ground, they need to build a shady place to have a quiet rest. Then keep spraying the body of the cow with cool water, especially the head, to drink a lot of cool water or salt water, which helps to cool and regulate the body temperature. After the re-emergence of neurological symptoms, intravenous injection of 00~1000mL 25% mannitol or sorbitol should be given to diseased cattle, and the dose of calves and adult cattle should be reduced appropriately. When sick cattle are excited, 500~1000mL 5% sodium bicarbonate can be injected intravenously; when breathing difficulty, 500~1000mL glucose and sodium chloride can be injected intravenously.

4. Preventive methods

In the construction, the cowshed must be spacious and high, it is best to sit north to south, install enough windows for ventilation, the top floor of the cowshed must build thermal insulation, the thermal insulation can be foam, so it can be warm in winter and cool in summer. In times of high temperature, open the window to make the air convection, take away the heat, reduce the breeding density, and build a sunshade net on the roof or an awning around the cowshed to avoid direct sunlight. When the sun is strongest at noon, sprinkle water on the house droplets and the ground to reduce the temperature of the barn, but pay attention to ventilation to avoid high temperature and humidity, which is even more disadvantageous to the growth of beef cattle. An appropriate amount of salt can be added to drinking water, which can help beef cattle to metabolize, regulate body temperature and help to dissipate heat.
