摘 要
本文探讨了猪圆环病毒病的临床症状、发病机理及防控策略。临床症状主要包括体质下降、呼吸困难和渗出性皮炎等，这些症状对猪只的健康构成严重威胁。在发病机理方面，猪圆环病毒通过入侵宿主细胞，抑制免疫系统功能，导致猪只易于继发感染和引发并发症。针对猪圆环病毒病的防控，本文提出了多项策略：首先，加强猪场管理，包括改善饲养环境和提高饲养管理水平，以减少病毒传播的机会；其次，使用免疫增强剂，提高猪只的免疫力，增强其抵抗病毒感染的能力；再者，预防细菌感染，通过合理的抗生素使用和消毒措施，降低继发感染的风险；最后，加强并发症护理，及时发现并处理并发症，以减少疾病对猪只的影响。本研究为猪圆环病毒病的防控提供了理论依据和实践指导，对保障养猪业的健康发展具有重要意义。

Abstract
This paper discusses the clinical symptoms, pathogenesis and control strategies of porcine circovirus disease. The clinical symptoms mainly include physical decline, dyspnea and exudative dermatitis, which pose a serious threat to the health of pigs. In terms of pathogenesis, porcine circovirus is prone to pigs by invading host cells and inhibiting immune system function, leading to secondary infection and causing complications. For the prevention and control of circovirus disease in pigs, this paper proposes a number of strategies: first, strengthen the management of pig farms, including improving the feeding environment and feeding management to reduce the chance of virus transmission; second, the use of immune enhancer to enhance the immunity and resistance to virus infection; prevent bacterial infection and reduce the risk of secondary infection through reasonable antibiotic use and disinfection measures; finally, strengthen the care of complications, and detect and handle complications in time to reduce the impact of disease on pigs. This study provides theoretical basis and practical guidance for the prevention and control of porcine circovirus disease, and is of great significance to ensure the healthy development of the pig industry.
