摘 要: 猪繁殖与呼吸综合征造成养猪产业巨大经济损失,预防和消除该病已成为世界性难题。本文根据猪繁殖与呼吸综合征流行病学特性,结合规模化猪场生产管理实际,采用风险列举法对规模猪场PRRS传入和场内传播流行的风险因素进行了系统分析。提出规模猪场PRRS风险因素主要包括猪场选址、用品和工具进入、员工和访客进入、活猪运输、饲料运输、死猪处理、粪便管理、猪舍条件、生物传播媒介、引种等外部风险因素和PRRSV状态、管理措施、猪只流动、设施条件、协同病原、猪舍布局等内部风险因素。这为进一步开展规模猪场PRRS风险评估研究,制订科学有效的PRRS风险管理措施奠定了良好基础。 Porcine reproductive and respiratory syndrome (PRRS) causes major economic losses in the pig industry, and prevention and elimination of the disease has become a worldwide problem. In this paper, based on the epidemiological features of PRRS and combined with large-scale pig production management practices, risk factors for infection of pig herds with PRRSV in large-scale Pig farms were systematically analyzed using census and enumeration method. We suggested that the risk factors for introduction and spread of PRRSV include external risk factors such as location factors, entry of supplies, employee and service vehicles, employees and visitors, transportation of live pigs, transportation of feed, disposal of dead animals, manure management, facilities, bio-vectors, source of pigs and internal risk factors such as PRRSV status, management practices, flow of pigs, facility condition, vaccine use, other disease challenges, herd and site characteristics. This will provide a good reference for risk assessment of PRRS and development of scientific and effective PRRS risk management measures.
