<h1>Sheep pancreatic fluke disease, also known as sheep broad disc fluke disease, is a parasitic disease caused by trematodes of the genus Diplodocetes in the sheep pancreatic duct that causes inflammation, anemia and nutritional disorders in the pancreatic ducts of the sheep. This trematody requires the participation of two intermediate hosts (the first intermediate host is a land snail and the second intermediate host is a grasshopper) during development. The main popular seasons are spring and autumn, especially autumn. </h1>
Symptoms of pancreatic fluke disease in sheep
Due to the mechanical stimulation and toxin action of the insect body, it can cause chronic proliferative inflammation and progressive necrosis of the mucosal epithelium in the sheep pancreatic duct, resulting in thickening of the tube wall, narrowing or even occlusion of the lumen, and obstruction of pancreatic juice discharge, resulting in digestive disorders. Symptoms are not obvious in mildly infected people, severely infected people show emaciation, dry coat color, anemia, diarrhea, feces with mucus, submandibular, neck and chest edema may appear, and finally fall into cachexia and die.
Prevention of pancreatic fluke disease in sheep
(1) In the epidemic area, the sheep are generally inspected for feces from March to April every year, and the positive sheep are treated head by head to reduce the pollution of the pasture by insect eggs.
(2) Because the second intermediate host grasshopper is widely distributed and difficult to eradicate, it mainly takes the killing of the first intermediate host land snail to cut off its life chain, which can be artificially captured when the land snail has just recovered from the soil in May to June every year and has not yet begun to reproduce, and concentrated fire or smashed into deep burial.
(3) Zoning grazing to prevent re-infection.
(4) Cultivate healthy flocks without trematodes, lambs start from weaning, move to the absolute safety area for grazing management, and expand the healthy sheep year by year, and finally achieve the purpose of complete purification.
