Symptoms and Treatment of Heat Stroke in Pigs
High temperatures in summer can lead to heat stroke in pigs if not managed properly, significantly affecting the herd. The symptoms of heat stroke in pigs are quite noticeable, and timely treatment is crucial. What are the symptoms and treatment methods for heat stroke in pigs? Let’s take a look.
I. Symptoms of Heat Stroke in Pigs
1. Elevated Body Temperature
When pigs suffer from heat stroke, their body temperature rises significantly, exceeding the normal range.
2. Rapid Breathing
Due to the increased body temperature, pigs will breathe rapidly to dissipate heat. Rapid breathing is a common symptom of heat stroke in pigs.
3. Cyanotic Lips
During heat stroke, pigs may show cyanosis (a bluish discoloration) of the lips due to insufficient oxygen supply.
4. Lethargy
Pigs affected by heat stroke will exhibit lethargy and appear listless and fatigued.
5. Reduced Appetite
Heat stroke causes a noticeable decrease in the pigs' appetite, and they may even refuse to eat.
6. Diarrhea
Heat stroke can disrupt the pigs' digestive system, leading to symptoms of diarrhea.
II. Treatment Methods for Heat Stroke in Pigs
1. Cooling Therapy
If the pig's body temperature is excessively high, physical cooling should be the primary approach. Move the affected pig to a shaded area and use cold, wet towels on its head or left chest area. Alternatively, spray cool water over the pig’s head and body, focusing more on the head. Encourage the pig to drink water.
2. Bloodletting Therapy
For acute heat stroke, quickly move the pig to a ventilated, shaded area. Cut the tip of the pig’s ear or tail to release 100-200 milliliters of blood. Administer 5-10 milliliters of aromatic ammonia spirit diluted in water orally, and inject 200-500 milliliters of compound sodium chloride intravenously.
3. Herbal Therapy
For heat stroke, give the pig a decoction made from 100 grams each of Houttuynia cordata, wild chrysanthemum, and light bamboo leaves, along with 25 grams of orange peel.
4. Western Medicine Therapy
For severe cases, administer 0.5-2 grams of sodium benzoate caffeine subcutaneously or intramuscularly, along with 10-20 milliliters of aromatic ammonia spirit, mint water, or camphor water orally. For overly excited pigs, inject 1-3 milligrams of chlorpromazine per kilogram of body weight intramuscularly. For severe dehydration, administer 200-500 milliliters of saline or 5% glucose saline intravenously.
III. Prevention and Management
Install cooling equipment like air conditioners or fans in the pigsty to effectively control the temperature and humidity, maintaining a comfortable environment.
In conclusion, recognizing the symptoms and applying timely treatments are crucial in managing heat stroke in pigs. Proper preventive measures can significantly reduce the risk of heat stroke in your herd.
