A case of suspected erythrocytic disease in pigs
In the hot and rainy season in the south, a large number of blood-sucking insects breed. In poorly sanitation farms, pigs' walls, pig utensils or pigs are covered with a lot of flies during the day; at night, they enter the piggery and often hear the buzz of mosquitoes. Pigs are often bitten by mosquitoes and can easily cause Eperythrozoonosis in pigs. Not long ago, the author received calls from pig farmers in Guangdong, Hainan, Fujian, Yunnan, Guangxi, and Jiangxi to reflect the situation of Eperythrozoonosis in pigs. In early June of this year, the author went to a pig farm in a suburb of Guangzhou to diagnose pig disease and also found that the pig was suspected to have erythrocytic disease. The pig farm bought 300 piglets from outside, about 25 kilograms, and the body was red, hot, and not eating. The disease occurred for 3 days and died.
Clinical symptoms
Clinical observation: The sick pigs are depressed, unresponsive, have shortness of breath, some lying ground, loss of appetite, or no food, body temperature 40.5°C～41.5°C, showing heat retention; some pigs have ear, lip, tail, The lower abdomen and extremities became red, some of the affected pigs had visible pore bleeding and rust color, and a "bleeding belt" was formed from the neck to the back of the scapular part. Some pigs were pale and yellow, and the conjunctiva was slightly swollen, flushed and pale. Yellow dye, yellowish urine, reddish or reddish-brown, twitching limbs before death, extremely difficult to breathe, and died of exhaustion.
Pathological changes
Pigs dissected and diseased, blood thin red cherry, poor coagulation; hepatic steatosis, enlargement, pale yellow; bile thick, gallbladder wall swelling; splenomegaly, edge of a large infarct of purple infarct in the infarct; submandibular Swelling of hilar lymph nodes in the hilum was khaki, with enlarged lymph nodes, ectropion of the face, mild yellow staining, and yellow-white necrosis; mucosal congestion at the bottom of the stomach, blood stasis, and mung bean-sized bleeding in the small intestine. There is a small amount of hemorrhage under the kidney capsule, and there are needle-point bleeding points in the renal pelvis and kidney papilla; the bladder mucosa is yellow-stained and has a slight bleeding point.
diagnosis
Due to the limited conditions at the time, laboratory tests were not conducted. According to the incidence, clinical symptoms, and pathological changes, the pigs were primarily diagnosed with Eperythrozoonosis.
Treatment and results
treatment
(1) Weak pigs with severe hematuria and no food at all, one side of the neck was injected with Hengfeng strong sense red bow chain (0.1 ml/kg.w) and Qing Kai Ling (0.2 ml/kg.w); The other side was intramuscularly injected with 0.25 g of sulfamethoxazole; once daily for 3 consecutive days.
(2) medication with spices. Each 500 kilograms of material is mixed with 500 grams of Hengfengqiang Antiviral No. 1 powder, 300 grams of sulfamethoxazole sodium, 150 grams of doxycycline, and 100 grams of trimethoprim. The mixture is well-mixed for free use of diseased pigs for 5 days; Vitoli (supplemental vitamins, especially vitamin K3 supplements, to promote rehabilitation) 500 liters of water 1000 liters, for the pig to drink for 7 days.
(3) Do a good job of eliminating insects such as mosquitoes and flies and rodent control, and properly modify the pig house according to the actual situation, and install the fine-hole anti-mosquito mosquito screen on the opening of the pig house.
