摘　　要：鸡大肝大脾病是由病毒、细菌或寄生虫等病原体引起的以肝脾肿大为特征的传染性疾病,该病可增加鸡死亡率并影响其产蛋量,给养殖业带来巨大经济损失。通过流行病学方法研究鸡大肝大脾病发生发展规律,对其防控具有重要意义。为探究影响鸡大肝大脾病的风险因素,本调查收集了来自山东、河北和陕西等12个省的38份问卷,通过构建回归模型,发现鸡场距主干道距离和青年鸡来源对该疾病发生具有显著影响(P<0.05),是否进行弱毒疫苗外源性病毒检测对其可能具有潜在影响。据此,在符合生物安全的前提下,建议在主干道附近修建鸡场;同时,在条件允许情况下,尽量自繁自养青年鸡,并进行弱毒疫苗外源性病毒检测。本调查结果可辅助鸡场管理者制定合理有效的方案,为预防鸡大肝大脾病提供重要参考,对防控其他疾病风险也具有一定的借鉴价值。Big liver and spleen disease(BLS) in chickens is an infectious disease characterized by the enlargement of the liver and spleen,caused by viral,bacterial,or parasitic pathogens.This disease could increase chicken mortality and affect egg production,resulting in significant economic losses for the poultry industry.Understanding the epidemiological patterns of BLS through research is crucial for its prevention and control.To investigate the risk factors influencing BLS,this study collected 38 questionnaires from 12 provinces including Shandong,Hebei,and Shaanxi.By constructing a regression model,we found that the distance of the chicken farm from the main road and the source of young chickens significantly impacted the occurrence of BLS(P<0.05).Additionally,the detection of exogenous virus in attenuated vaccines might have a potential impact.Based on these findings,we recommend building chicken farms near main roads,provided that biosecurity measures are adhered to.Furthermore,when possible,farms should consider breeding and raising their young chickens and conducting exogenous virus detection for attenuated vaccines.The results of this survey can assist farm managers in developing rational and effective strategies for preventing BLS,providing important references for controlling the risks of other diseases as well.
