Pig eczema breaks out frequently during the rainy season: how can it be prevented and treated scientifically?

Pig eczema, also known as pig eczema toxemia, is mainly caused by pigs living in a damp environment for a long time, and the outbreak rate of this disease is especially high in hot seasons.

1. Symptoms. Most acutely affected pigs develop the disease suddenly. At the beginning of the disease, the skin under the jaw, on the abdomen and on both sides of the perineum turns red, and broad bean-sized nodules appear at the same time, with itching and restlessness. Later, as the condition worsens, blisters and papules appear on the skin of the affected pigs. After the blisters and papules rupture, they are often accompanied by yellow exudate, and finally form scabs or turn into scales. If acutely affected pigs are not treated in time, they often turn chronic. Because the skin becomes thick and itchy, pigs often rub against walls and trees to relieve itching, resulting in hair loss over the whole body, local infection, erosion or suppuration, and over time the pigs become emaciated and die of weakness.

2. Prevention. In hot seasons, do not accumulate manure inside the pig house. Instead, clean the pig pen frequently to keep the house clean and dry. At the same time, prevent rain leakage in the pen, often put bedding straw under the sun to dry, and if the walls are very damp, sprinkle some lime to remove moisture.

3. Treatment. For acute cases, pigs can be injected intravenously with 10-20 milliliters of calcium chloride or calcium gluconate, and at the same time orally given 5000 international units of vitamin A and 0.5-2 grams each of vitamin C tablets and compound vitamin B tablets. If necessary, 0.5-1.5 milliliters of adrenaline can be injected. For affected pigs with flushing and papules at the lesions, 1 gram of ichthammol, 1 gram of salicylic acid and 30 grams of zinc oxide ointment can be mixed and applied. For pigs with chronic eczema toxemia, first wash the affected area with soapy water, then apply 10% sulfur coal tar ointment for external washing treatment. If the affected area of the pig is suppurating and infected, first clean it with 0.1% potassium permanganate solution or 0.3% nitrofural solution, then apply sulfonamide tincture or sprinkle anti-inflammatory powder.
