Causes and Control of Immune Failure of Infectious Coryza in Chickens

鸡传染性鼻炎又被称为鸡副嗜血杆菌病,是由鸡副嗜血杆菌感染引起的一种呼吸道疾病,临床上主要表现为咳嗽,打喷嚏,眼部肿胀,流泪。该病在鸡群中传播速度较快,会使养殖场鸡群的淘汰率显著升高,产蛋率显著下降,给养殖户带来严重的经济损失。临床上鸡传染性鼻炎的发生具有一定的季节性,常发生于每年秋末冬初。在疾病防范中做好该种传染性疾病的免疫接种工作,能有效降低发病率,保证鸡群健康生长。但在疫苗免疫接种中,由于受到多种因素的影响,经常造成鸡传染性鼻炎免疫失败,造成疫情的传播流行,影响鸡群健康生长。该文主要论述传染性鼻炎免疫失败的原因及防控措施。

Avian infectious rhinitis,also known as haemophilus parasuis,is caused by an infection called haemophilus parasuis that causes coughing,sneezing,swelling and tearing in the eyes,according to the respiratory disease.The disease spreads quickly in the flock of chickens,which will increase the elimination rate and decrease the egg production rate,and bring serious economic losses to the farmers.The incidence of infectious coryza in chickens is seasonal and usually occurs at the end of autumn and the beginning of winter.Vaccination of the infectious disease in disease prevention can effectively reduce the incidence of disease and ensure the healthy growth of chicken flocks.However,in the course of vaccination,due to the influence of many factors,it often causes the failure of immunity of infectious rhinitis in chickens,which causes the spread of epidemic situation and affects the healthy growth of chickens.This article mainly discusses the causes of immune failure of infectious rhinitis and its prevention and control measures.
