禽养殖场禽流感发生率影响因子研究进展

摘要

近年来,禽流感受到全球高度关注,禽类为流感病毒的基因贮存库,禽养殖场发生禽流感将产生极大的社会负面影响.综述养殖过程中养殖场禽流感发生率的影响因子,包括养殖前期的选址、水源情况、养殖分区,初孵雏或种蛋的选择,养殖过程中的养殖品种、养殖密度、卫生消毒、人员管理、免疫接种等.就我国目前而言,导致风险的主要原因是农户认知水平低和政府相关政策的不完善,国家宏观调控措施的施行可有效降低禽流感发病率.%In recent years,avian influenza (AI)has received global attention.Social negtive influence will bring up if AI occur in poultry farms,for poultrys are AI virusg gene store pool.Influencing factors of incidence of AI were reviewed in the whole breeding process of poultry farms,including the early stage of the choice of location,water source,and culturing partition choice of day-old birds or hatching eggs,in the process of breeding,breeding density,sterilizing,personnel management,immunization,etc..In terms of our country at present,the main reasons of occurring AI were due to the low level of farmers cognition and relevant government policy.Enforcement of state macro-control measures can effectively reduce the incidence of AI.
