支原体感染引起鸡慢性呼吸道疾病防治

Prevention and Treatment of Chronic Respiratory Disease Caused by Mycoplasma Infection in Chickens

引发鸡呼吸道疾病的致病原多种多样,不同的致病原表现的致病性、致死率存在很大差异性。支原体是引起鸡慢性呼吸道疾病的常见致病原,该种疾病虽然造成的死亡率较低,但是一旦在鸡群中爆发流行,会存在隐性带菌鸡,使养殖场反复感染该种传染性疾病,造成严重危害。临床上患病鸡主要表现为咳嗽、流鼻涕、气管啰音。有的患病鸡还会表现为关节炎症状,关节肿大不能正常行走。雏鸡感染该种致病原后表现为生长发育不良,成年大鸡感染后表现为产蛋率下降。支原体感染引发的慢性呼吸道疾病具有发病时间长反复流行的特点,易与其他传染性疾病继发感染并发感染。各种应激因素是造成该种疾病爆发流行的主要原因。该文主要论述支原体感染引发鸡慢性呼吸道疾病的诊断和防治过程。

Climate changes in winter and spring,abnormal temperature changes,whether in the external environment or in the breeding environment,there are many stress factors,if not properly do a good job of chicken breeding management,easy to cause stress stimulation,chicken body resistance to reduce the ability to provide conditions for the proliferation of a variety of pathogenic microorganisms.In the event of an outbreak of infectious disease in farms,if not effectively controlled,spread to the entire population within a short period of time,will be devastating to the entire farming industry.The spring season is the peak period for the occurrence of various respiratory disease diseases and diarrheal diseases.In order to prevent the occurrence and prevalence of these diseases,it is necessary to pay attention to the diagnosis and treatment of the diseases and to improve the safety of breeding.In this paper,the diagnosis and treatment of common diseases are discussed according to the epidemic situation of common diseases in winter and spring.
