2例蛋鸡场鸡源鸭疫里默氏杆菌感染的治疗案例分析与防控体会OA

In recent years,the incidence of Riemerella anatipestifer of chicken origin in laying hen farms has in-creased year by year.Its clinical symptoms and necropsy characteristics are highly similar to those of avian colibacillo-sis,leading to frequent misdiagnosis and serious economic losses to farmers.At present,there are few reproducible treatment protocols and prevention and control experiences for Riemerella anatipestifer infection in laying hen flocks,and practical guidance is insufficient.Combined with the clinical practice of two infection cases in laying hen farms,this paper elaborates on the epidemiological profile,clinical symptoms,necropsy features and diagnostic process of Riemerella anatipestifer infection in chickens.It focuses on summarizing the successful treatment regimens,practical in-sights and prevention-control measures of the two cases,so as to provide practical references for the scientific diagno-sis,treatment and effective prevention and control of Riemerella anatipestifer infection in laying hen farms,and help farmers reduce losses caused by the disease.
