Symptoms and control of porcine pulmonary filariasis

Porcine pulmonary filariasis mostly occurs in low-lying and humid areas and summer and autumn seasons, showing an endemic epidemic, mainly harming pigs, affecting the growth and development of pigs and reducing meat quality, serious infection will cause pneumonia, resulting in death.

Symptomatic pigs are asymptomatic or insignificant in mild infection and significant in severe infection. More than a month after infection, pigs had paroxysmal cough, thick yellow mucus in nose, shortness of breath, pallor of conjunctiva, loss of appetite and weight loss, and some died of asphyxiation due to blockage of the trachea.

Prevention first, the implementation of self-breeding, do not buy pigs from other places, in order to reduce the introduction of sick pigs from the outside. Second, the pig house should be warm in winter and cool in summer, pay attention to ventilation and prevent overcrowding, keep the pig house clean and hygienic, pay attention to drainage and dryness, and put an end to the breeding of @ # @ 254 pig houses. Pig manure should be removed in time for composting and fermentation. 3. In the areas where the disease is endemic, 1% caustic soda water or 30% plant ash water can be used to disinfect pig houses and sports grounds. Fourth, preventive deworming on a regular basis, once or twice a quarter.

Treatment 1. Feed pigs with 13 tablets of levamisole hydrochloride (25 mg each). Second, use levamisole hydrochloride injection (deworming speed) 6 ml intramuscular injection. 3. Penicillin 800000 International Unit 2, kanamycin Sulfate injection 500000 International Unit 4, compound aminopyrine injection 20 ml, Dexamethasone Sodium Phosphate injection 5 ml, Houttuynia cordata injection 10 ml, mixed intramuscular injection, once a day for 3 consecutive days. IV. Endotracheal injection. 1.5g of potassium iodide, 3g of procaine and 1200 ml of distilled water were injected into the pig trachea. Once every 2 days, twice in a row, and then once every 10 days. Methods: the diseased pigs were lying on their back in Baoding, and the anterior part of the pig was raised, and the injection was carried out in the space between the four cartilage rings in front of the trachea. The injection process should be slow, after the injection, the pig body is tilted upward, and the pig is put down when the liquid reaches the bronchi. Endotracheal injection and intramuscular injection at the same time, the effect is better. 5. Ivermectin is injected subcutaneously at 0.3 mg per kilogram of body weight once a day for 2 days.
