How to prevent and cure pulmonary filariasis in sheep with cough, dyspnea and poor appetite

The pathogen of sheep pulmonary filariasis is pulmonary filariasis, which can be divided into two types: large filamentous reticulum nematodes and small (procircoidea nematodes). The large lung filament adult parasites in the trachea and bronchi of sheep, containing larval eggs or hatched larvae, which are spurted out with sputum, or swallowed and excreted through feces. The larvae can live freely in water and feces and grow into invasive larvae in 6-7 days, entering the blood from the digestive tract of the sheep, and then circulating from the blood to the lungs of the sheep.

Sheep

First, clinical symptoms: first, cough, first individual sheep attack, and then more and more. When the sheep are driven away, rest at night and come out in the morning, the cough is more obvious, auscultation of the lungs and wet rales. When coughing, mucus clumps are coughed up, and mucus secretions are often excreted from the nostrils of diseased sheep. After drying up, crusts are formed around the nostrils, often sneezing and difficulty breathing. Some of the diseased sheep had a high fever of 40 ℃ ~ 41 ℃, with pale visual mucosa, yellowing abdominal skin, reduced diet, pica, gradual weight loss, anemia, rough coat and no luster. Some diseased sheep developed submandibular, subthoracic and limb edema and died within a few days.

II. Prevention and treatment

(1) Sheep grazing can not reach low-lying and wet places and do not drink stagnant water. The feces are treated to kill the larvae. And do regular deworming.

(2) large pulmonary filariasis was treated by intratracheal injection of iodine solution. Use iodine tablets 1g, potassium iodide 1.5g, distilled water 1500 ml, boil and disinfect, cool to 20-30 ℃, and then give tracheal injection. Dose: 8ml for lambs, 10ml for young sheep, 13ml for adult sheep, once injection.

(3) endotracheal injection of sodium salicylate solution to treat small pulmonary filariasis. After disinfection, 5 grams of sodium salicylate plus 100 ml of distilled water was injected into the trachea. Adult sheep 20 ml, young sheep 10-15 ml, one injection.

(4) treated with tetraimidazole. According to the sheep per kilogram of body weight 7-25 mg internal administration, or mixed into water, intramuscular injection.

(5) treatment with benzothiamidazole. According to the sheep per kilogram body weight 10-15 mg, one-time oral administration or mixed into an injection, intramuscular injection.
