规模化种猪场伪狂犬病综合防控及净化措施

Comprehensive Control and Purification Measures of Pseudorabies in large-scale Breeding

猪伪狂犬病被世界动物卫生组织归为B类传染病,属于急性、热性、高度接触性传染病。主要发病特征为神经症状及繁殖障碍,对规模化种猪场的威胁极大。猪伪狂犬病多呈隐性感染,临床症状表现多样,很难有效将其净化清除,给规模化种猪场的日常防疫工作带来巨大挑战。该文以2020年四川省达州市某规模化猪场感染猪伪狂犬病为例,并针对猪伪狂犬病预防、检测、净化等综合防控措施展开讨论,以期降低该病对生猪业带来的经济损失。

Porcine pseudorabies(PRV)is classified as a Class B infectious disease by the World Organization for Animal Health(OIE).It is an acute,febrile and highly contagious disease.The main symptoms of the disease are neurological symptoms and reproductive disorders,which threaten large-scale breeding pig farms.Pseudorabies(PRV)is a recessive disease with various clinical symptoms.It is difficult to clean it effectively,which brings great challenge to the routine epidemic prevention of largescale breeding pig farms.In this paper,a case of pseudorabies infection in a large-scale pig farm in Dazhou in 2020 was taken as an example,and the integrated control measures including prevention,detection and purification of pseudorabies were discussed,in order to reduce the economic losses of the disease to the pig industry.
