摘要
高致病性禽流感(HPAI)是严重威胁我国禽养殖业健康持续发展的重大疫病。养殖场是禽类的高聚集区,存在较大的HPAI潜在暴发风险。本文在已有研究文献基础上,按照流行病学和风险关键控制点原则,从养殖场层面,分析提出了HPAI的主要传入风险因素及控制措施。分析认为,野生鸟类及相关区域、易感动物及相关场所、种蛋/雏鸡、水源、饲料、流通运输及运输工具、人员、消毒剂及疫苗等投入品是主要风险因素,需要针对这些因素,从场区规划布局、屏障建设、日常饲养、制度管理4个方面,采取相应生物安全措施,以降低禽养殖场HPAI的传入风险。
Highly pathogenic avian influenza(HPAI)is a major disease that seriously threatens the healthy and sustainable development of Chinese poultry industry.Farms are the highly concentrated areas for poultry,where the potential risk of HPAI outbreak is relatively high.Based on the current researches,the main risk factors and control measures of HPAI were analyzed from the farm level according to the principles of epidemiology and risk control points.Results showed that,the main risk factors were wild birds and related areas,susceptible animals and related places,eggs/chickens,water sources,feed,transportation and transportation vehicles,personnel,disinfectants and vaccines,etc.Aiming at these factors,corresponding bio-safety measures should be adopted from4aspects of site planning and layout,barrier construction,daily raising,and system management,so as to reduce the risk of HPAI being released into poultry farms.
