What are the prevention and treatment methods for heatstroke in pigs in summer

As the global climate warms, summer temperatures rise year by year, and pigs with poorer heat dissipation capacity are more prone to heatstroke. Farmers should take measures to prevent and treat heatstroke in pigs.

Clinical symptoms: sudden onset, sharp rise in body temperature, rapid and difficult breathing, highly depressed spirits, weakness of the limbs, ataxia, and profuse sweating over the whole body. If treatment is not timely or is unreasonable, the animal lies down and cannot rise, and dies from spasms or coma.

Prevention: 1. The pig house must have good ventilation, and a shed should be built for shade to prevent direct sunlight. 2. Maintain good environmental hygiene inside and outside the pig house, and frequently splash the ground with cool water. 3. The stocking density of pigs in the house must not be too high. 4. Ensure there is enough drinking water, especially at noon and in the evening every day; an appropriate amount of salt should be added to the drinking water to replenish the body salts lost through sweating.

Treatment: 1. Immediately move the sick pig to a well-ventilated, shady place, give it an enema with cool water, and have it orally take a large amount of 2% cool salt water or other cooling agents. 2. Bleed 50-250 ml from the vein, then inject intravenously 500 ml of 5% glucose saline and 5 ml of 20% sodium caffeine benzoate solution, once a day for 3 consecutive days. 3. Inject intravenously 300 ml of compound sodium chloride solution and 3 ml of 20% sodium caffeine benzoate solution, once a day for 3 consecutive days.
