Abstract: Porcine pseudorabies is a serious infectious disease that difficult to control in the current large?scale pig?breeding industry. The disease is highly contagious and has a high mortality rate in clinical production and tends to form latent infections，making it difficult to remove the pathogen completely and bringing great economic losses to the pig farming industry. In this paper，based on the relevant biological characteristics of porcine pseudorabies，the systematic diagnosis and epidemiological analysis of the disease are on the basis of the clinical symptoms and pathological changes of porcine pseudorabies. And in accordance with the actual production situation，targeted prevention as well as control and purification measures are put forward，effectively interrupting the potential harm and prevalence of the disease. These relevant methods and technologies will provide reference for the prevention and control of similar diseases，with a view to helping the stable and healthy development of pig industry.
