家禽常见疾病发生特点及防治

Occurrence Characteristics and Control of Common Poultry Diseases

家禽养殖产业集约化规模化发展,为养殖户带来经济效益的同时也面临较大的疫病防范风险。目前传染性疾病已经成为威胁家禽养殖产业健康发展的主要影响因素,且很多传染性疾病表现出复杂的临床症状,疾病诊断难度越来越大。再加上各类免疫抑制性疾病的存在,鸡群抗体水平普遍降低,大多数鸡群处于亚健康状态,抵抗能力较差,一旦受到诸多应激因素的影响,会给多种病原的侵染混合感染提供条件,给兽医疾病诊断工作带来很大难度。

The intensive and large-scale development of the poultry breeding industry brings economic benefits to farmers,but also faces a greater risk of disease prevention.At present,infectious diseases have become the main factors that threaten the healthy development of the poultry breeding industry,and many infectious diseases show complex clinical symptoms,making the diagnosis of diseases more and more difficult.Coupled with the existence of various immunosuppressive diseases,the antibody level of chickens is generally reduced.Most chickens are in a sub-healthy state and have poor resistance.Once affected by many stress factors,they will be infected with multiple pathogens.Mixed infections provide conditions and bring great difficulty to the diagnosis of veterinary diseases.
