Abstract:Pig blue ear disease is an infectious disease caused by a virus in pigs, which seriously affects pig production and breeding industry. Therefore, we have always adhered to the prevention and control policy of focusing on prevention, taking source control, classified guidance, and gradient promotion as prevention and control, and strictly implemented comprehensive prevention and control measures such as immunization prevention, laboratory testing and purification, quarantine supervision, emergency disposal, and harmless treatment. Laboratory monitoring is the most important means to reduce the incidence rate, compress the epidemic range, and gradually achieve the purification goal. However, there are some problems in the process of detecting pig blue ear disease in the laboratory. Below,this paper mainly explore some existing problems and corresponding solutions.
