牛呼吸道疾病综合征诊断技术研究进展OACSTPCD

Bovine respiratory disease complex(BRDC),also known as"Shipping fever",is a generic term for respiratory system diseases,which includes pneumonia and bronchitis,caused by many kinds of bacteria,viruses and diverse physiological stresses,and occurs at high frequency among calves.BRDC is widely distributed around the world,causing huge economic losses to the global cattle farming industry.With the development of cattle industry in China,BRDC has been diagnosed at beef cattle farms and dairy farms in many provinces,and severely impeded the healthy development of cattle industry in China.Because of complex etiology and difficulty in treatment,it is crucial to develop accurate and fast diagnostic method for the prevention and control of BRDC.This review summarized research achievement about diagnostic techniques of BRDC for decades to provide reference for the prevention,control and in-depth research of this disease.
