What are the prevention and treatment methods for sheep heartwater disease?

Livestock Farming 0 views
Sheep heartwater disease is a non-contagious infectious disease that frequently occurs in sheep flocks. The disease is generally caused by a cold with high fever. A large amount of yellow blood-containing fluid accumulates in the pericardium of affected sheep, causing rickettsial pathogens in the vascular endothelial cells of the cerebral cortex and renal glomeruli to attach to red blood cells, and the disease spreads to healthy sheep through the blood-sucking transmission of ticks. In sheep suffering from acute heartwater disease, body temperature rises above 42°C, breathing is rapid, pulse is short and fast, they refuse to eat, grind their teeth, protrude their tongue, walk unsteadily, and fall

Sheep heartwater disease is a non-contagious infectious disease that frequently occurs in sheep flocks. The disease is generally caused by a cold with high fever. A large amount of yellow blood-containing fluid accumulates in the pericardium of affected sheep, causing rickettsial pathogens in the vascular endothelial cells of the cerebral cortex and renal glomeruli to attach to red blood cells, and the disease spreads to healthy sheep through the blood-sucking transmission of ticks.

In sheep suffering from acute heartwater disease, body temperature rises above 42°C, breathing is rapid, pulse is short and fast, they refuse to eat, grind their teeth, protrude their tongue, walk unsteadily, fall to the ground and convulse, with the head tilted backward, and die from convulsions. Necropsy reveals hemorrhage of the endocardium and epicardium, large amounts of fluid accumulation in the pericardium, chest and abdominal cavities, the pharynx, larynx and trachea filled with fluid, and mucosal congestion. Similar lesions are found in the stomach and intestines, and other organs show congestion and enlargement.

To effectively prevent and treat sheep heartwater disease, first, management of sheep should be strengthened to prevent colds and fever; second, sheep medicated baths and fly control should be carried out in epidemic areas. In the early stage of fever in affected sheep, treatment with sulfadimidine is effective, and intravenous injection of oxytetracycline combined with analgin can also be used, with even better results.
