Poultries of different age are confronted with different disease threats and it is necessary to take relevant measures to prevent and control them to decrease the disease risks.A survey was conducted by collec⁃ting 331 questionnaires on broiler farmers in order to understand whether farmers take different epidemic pre⁃vention measures according to chicken’ s different ages and their influence factors. It was found that although more than 80% of the farmers carried out accurate epidemic prevention measures,quite a number of farmers whose consciousness of anti⁃risk were weak lacked initiatives on the measure at present.It was also found that farmers’work experience outside,breeding scale and purchased price of chicken delivered,their participation in epidemic prevention training,and availability of epidemic prevention technology and service around posed significant and positive influence on their behavior of taking relevant epidemics prevention measures for chick⁃en of different day⁃age.It may be a valid way to advocate scaled feeding,organize epidemics prevention training regularly and improve the availability of technology and service of epidemics prevention and control.%家禽在不同日龄面临不同的疫病威胁，需要采取相应的措施进行预防，才能降低禽群的患病风险。为了解养殖户是否根据肉鸡不同日龄采取不同防疫措施及其影响因素，通过收集6省331个肉鸡养殖户的调查问卷发现，虽然八成养殖户已经实行精准防疫，但仍有相当一部分养殖户缺乏执行积极性，防疫意识薄弱。 Logit模型的结果表明，养殖户是否有外出打工经历、养殖规模、出栏肉鸡收购价、是否参加防疫培训、周边防疫技术服务便利性、地区因素等显著且正向影响他们在肉鸡的不同日龄采用相应防疫措施的行为。提倡规模化养殖、定期组织防疫培训以及推动防疫技术服务的便利性可能是提高养殖户科学饲养管理的有效途径。
