规模化猪场口蹄疫的防控难点与对策研究
摘 要
本文针对规模化猪场口蹄疫的防控难点与对策进行了研究。首先分析了口蹄疫病毒的特性、传播途径及临床症状，指出了规模化猪场口蹄疫流行的主要特点。随后，从病毒高度传染性、疫苗保护效果有限、紧急防控措施执行难度以及规模化养殖特有问题等方面，详细阐述了规模化猪场口蹄疫防控的难点。针对这些难点，本文提出了强化生物安全措施、优化疫苗使用、提升应急处理能力以及改进养殖模式与环境等防控对策。通过加强猪场内外生物安全、提高疫苗匹配性和免疫效果、建立快速反应机制和优化病畜处理流程、调整养殖密度和改善养殖场所布局等措施，旨在构建一套综合防控体系，有效降低口蹄疫在规模化猪场中的发生风险，保障养猪业的健康稳定发展。

RESEARCH ON DIFFICULTIES AND COUNTERMEASURES OF FOOT-AND-MOUTH DISEASE IN LARGE-SCALE PIG FARMS
ABSTRACT
This paper studies the difficulties and countermeasures of foot and mouth disease in large-scale pig farms. Firstly, the characteristics, transmission route and clinical symptoms of FMD virus were analyzed, and we pointed out the main characteristics of FMD epidemic in large-scale pig farms. Subsequently, the difficulties in the prevention and control of foot-and-mouth disease in large-scale pig farms were elaborated in detail from the aspects of high infectivity of the virus, limited vaccine protection effect, the difficulty of implementing emergency prevention and control measures and the problems specific to large-scale breeding. In view of these difficulties, this paper puts forward the prevention and control measures such as strengthening biosafety measures, optimizing the use of vaccines, improving the emergency treatment capacity, and improving the breeding mode and environment. By strengthening the pig inside and outside biosafety, improve the vaccine matching and immune effect, establish rapid response mechanism and optimize treatment process, adjust the density of breeding and improve the breeding layout, aims to build a comprehensive prevention and control system, effectively reduce the risk of foot and mouth disease in scale farms, guarantee the healthy and stable development of pig industry.
