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.

摘要： 猪伪狂犬病是目前规模化生猪养殖生产中一种危害较为严重且难以防控的疫病， 该病在临床生产中传染性强，死亡率高，且易形成隐性感染，很难将病原彻底清除，给生猪养 殖业带来很大的经济损失。本文在猪伪狂犬病原相关生物学特性的基础上，根据猪伪狂犬病 的临床症状及病理变化，对该病进行系统诊断及流行情况分析，并根据实际生产情况提出了 针对性的防控及净化措施，有效阻断了该病的潜在危害及流行，相关方法和技术将为同类疫 病的防控提供借鉴参考，以期为生猪业稳定健康发展提供帮助。
