Abstract [Objective] The research aimed to study the prevalence situations of porcine reproductive disturbance diseases in Chuxiong Prefecture. [Method] Using serological methods， the infection situations of 6 kinds of porcine reproductive disturbance diseases in Chuxiong Prefecture during 2012～2014 were investigated. [Result] In Chuxiong Prefecture， the total positive rate of porcine circovirusⅡ-type disease was 89.41%， and the total positive rate of porcine pseudorabies， porcine parvovirus disease， Japanese encephalitis， porcine chlamydiosis and porcine toxoplasmosis were 47.00%，47.46%，49.39%，24.36% and 23.98% respectively. [Conclusion] These six kinds of reproductive disturbance diseases were widely prevalent in Chuxiong Prefecture. The investigation results could provide some reference basis for controlling the prevalence of reproductive disturbance diseases.

近年来，随着楚雄州养殖业的快速发展，商品猪和种猪跨地区交易频繁，造成部分传染病不断发生，病情日益复杂，不仅给动物疫病防控工作带来了巨大挑战，而且严重制约着楚雄州养殖业的健康发展。为了保障楚雄州养殖业的健康发展，笔者从2012年至2014年对楚雄州猪圆环Ⅱ型病毒病、伪狂犬病、细小病毒病、弓形虫病、乙型脑炎和衣原体病等6种繁殖障碍性疫病感染情况进行了调查，基本摸清了楚雄州6种繁殖障碍性疫病感染情况，为进一步防制猪繁殖障碍性疫病提供了一定的参考依据。
