低发病率、低死亡率、高淘汰率、散发性的非典型新城疫是放养土鸡的主要疫病之一，其流行病学、临床症状、剖检病变等不同于传统典型新城疫，易被误诊，给土鸡养殖业造成巨大的经济损失。文中对放养土鸡非典型新城疫的流行特点、成因及防控措施等进行概述，以期为土鸡养殖业者提供参考。

The atypical Newcastle disease is one of the main diseases in free-range chickens with low morbidity and mortality and high attrition rate, and has caused huge economic losses in free-range chicken production. It is usually sporadic and different from typical Newcastle disease in epidemiology, clinical symptoms and pathological lesions. Here we summarized epidemic characteristics, causes, and control measures of atypical Newcastle disease to provide references for free-range chicken breeders.
