非典型性鸡新城疫发生与综合防控

Occurrence and Comprehensive Prevention and Control of Atypical Chicken Newcastle Disease

新城疫曾经是鸡养殖领域最为严重的传染性疾病,近年随着对该种病毒性疾病的认知不断增强,再加上每年春秋两季重大疫病的集中免疫接种,以急性、高发病率和高死亡率的典型性新城疫在生产中并不多见,常以非典型的病例出现。由于临床症状轻微,再加上很多养殖户对非典型新城疫的认知不到位,经常会造成误诊,使养殖场不能及时采取措施进行有效的防控,给鸡养殖产业造成严重经济损失。该文主要论述非典型新城域的发生与综合防控。
