Emergency Measures for Heatstroke in Sows
Pigs are prone to heatstroke in summer, especially sows, which can result in symptoms such as lethargy, loss of appetite, and redness of the skin. Severe cases may even lead to death. Here, we'll introduce the most effective emergency measures for heatstroke in sows.
1. Physical Cooling
Immediately pour cool water over the head and body of the sow upon detecting signs of heatstroke. It's important to note that only a light amount of water should be poured over the head to prevent sudden contraction of blood vessels, which could lead to rupture. More water can be poured over the neck and lower body. Then, move the pig to a well-ventilated area. If the pig cannot be moved, place a powerful fan nearby to provide airflow.
2. Prompt Bloodletting
The quickest way to relieve heatstroke is to bleed from the tips of the ears and tail. Bleed 100 to 300 milliliters from the tips of the tail and ears and administer a suitable amount of 5% sugar-salt solution to prevent dehydration.
3. Full-body Washing
Use a mixture of warm water and herbal cooling solution to wash the entire body of the sow. Avoid pouring cold water directly onto the sow's body, as this can sometimes have the opposite effect. Another method is to spray a high-proof liquor or alcohol on the pig's head, which effectively reduces body temperature and alleviates symptoms.
4. Medical Treatment
After the condition stabilizes, administer oral medications to clear heat and toxins to consolidate the treatment. Intramuscular injection of aminophylline with penicillin and dexamethasone is recommended, with dexamethasone omitted for pregnant sows. For severely affected sows, administer subcutaneous or intramuscular injections of sodium benzoate caffeine at a dose of 0.5-2 grams per pig, along with oral administration of ten drops of water or peppermint water or camphor water at 10-20 milliliters.
5. Monitoring and Support
Continuously monitor the sow's condition and provide supportive care as needed. This includes ensuring access to clean water and a comfortable environment. If the sow's condition does not improve or worsens, seek veterinary assistance immediately.
6. Preventive Measures
To prevent heatstroke in sows, provide adequate shade and ventilation in the pig housing area. Ensure access to cool, clean water at all times. Avoid transporting pigs during hot weather and schedule activities during cooler times of the day.
These are the most effective emergency measures for heatstroke in sows. If a sow exhibits symptoms of heatstroke, it's crucial to take immediate action to prevent miscarriage or death.
