摘要
2015-2019年间,通过对上海市4家原种鸡场鸡群禽白血病的病原学监测,证实该病在鸡群中存在低水平感染。从基本概况、设施设备、生物安全、生产性能和临床表现、疫病净化情况等5个方面开展流行病学调查与分析,确定上海市原种鸡场具备净化基础,可推进实施该病的全面净化。
During the 2015-2019 period,the pathogenic monitoring of avian leucosis(AL)in the four protospecies chicken farms in Shanghai confirmed that there existed a low level of infection of avian leukosis virus(ALV)in chickens.Then,epidemiological investigation was carried out concerning five aspects,including basic situation,facilities and equipment,biosafety,production performance and clinical manifestation,and epidemic disease purification.It was found that the protospecies chicken farms in Shanghai possessed the purification foundation,and a comprehensive purification of the disease should be implemented.
