摘要
禽流感即人们所熟悉的禽流感病毒,以禽类多发,到目前也发现会传染包括人在内的哺乳动物,常见有马、猪,还有鲸鱼或海豹等.禽流感早已属于全球性传染病,特别多发于冬季和春季,其传染源主要是已患病的或携带该病毒的家畜家禽或野禽.禽流感的致病力也是不同的,毒力最强的是高致病性禽流感,其次是低致病性禽流感,还有一种是非致病性禽流感.高致病性禽流感致病力最强,可通过气溶胶、排泄物、食物等介质在群体之间水平方向传染,传播快,范围广,死亡率高.禽流感疫情带给家禽养殖业的影响是毁灭性的,家禽规模场必须做好预防管理,严格免疫、消毒、通风及饲料用药管理,完善好基础系统免疫,保证家禽养殖持续健康发展.
Abstract
AIV,also known as avian influenza,is common in birds and has been found to infect mammals,including humans,including horses,pigs,and whales or seals.Avian influenza has long been a global infectious disease,especially in winter and spring,and its infection source is mainly sick or carrying the virus of domestic poultry or wild birds.The pathogenicity of AIV is also different,the most virulent is highly pathogenic avian influenza,followed by low pathogenic avian influenza,and a non-pathogenic avian influenza.Highly pathogenic avian influenza has the strongest pathogenicity,and can be transmitted horizontally between groups through aerosol,excreta,food and other media,with fast spread,wide range and high mortality.The impact of bird flu epidemic on the poultry industry is devastating,therefore,poultry farms must do a good job of prevention and management,strict immunization,disinfection,ventilation and feed medication management,improve the basic system immunity,to ensure the sustainable and healthy development of poultry farming.
