摘 要
本文综述了猪伪狂犬病的定义、特点、分类及其对养猪业的深远影响，重点剖析了当前防控工作中面临的难点，并提出了针对性的优化对策。猪伪狂犬病作为一种由伪狂犬病病毒引起的急性传染病，具有高死亡率、生长性能下降及疫情难以根除等特点，对全球养猪业构成了严重威胁。防控难点主要包括生物安全管理不当、病毒变异频繁、临床症状复杂多变以及疫苗保护力不足等。为有效应对这些挑战，本文探索了建立全面生物安全体系、加强病毒监测与多种诊断方法的应用，以及选择并推广高效优质疫苗等优化防控策略。这些对策旨在为养猪业提供科学依据和实践指导，以期降低猪伪狂犬病的发病率和死亡率，保障养猪业的健康可持续发展，减少经济损失，为全球动物疫病防控贡献力量。

Abstract
This paper summarizes the definition, characteristics, classification of pig pseudorabies and its profound influence on the pig industry, focuses on the difficulties in the current prevention and control work, and puts forward targeted optimization countermeasures. As an acute infectious disease caused by pseudorabies virus, pig pseudorabies has the characteristics of high mortality rate, decreased growth performance and difficult to eradicate the epidemic situation, which poses a serious threat to the global pig industry. The difficulties in prevention and control mainly include improper biosafety management, frequent virus mutation, complex and changeable clinical symptoms, and insufficient vaccine protection. In order to effectively address these challenges, this paper explores optimized prevention and control strategies such as establishing a comprehensive biosafety system, strengthening the application of virus surveillance and multiple diagnostic methods, and promoting the selection and promotion of highly effective and high-quality vaccines. These countermeasures aim to provide scientific basis and practical guidance for the pig industry, in order to reduce the morbidity and mortality of pig pseudorabies, ensure the healthy and sustainable development of the pig industry, reduce economic losses, and contribute to the prevention and control of global animal diseases.
