为了解某规模化猪场消化道寄生虫的感染情况，以便对其科学制定防治措施提供参考，通过饱和盐水漂浮与水洗沉淀来分离猪粪便中虫卵或幼虫的方法，对苏州地区某规模化猪场进行了冬春两季消化道寄生虫调查。两次共检测猪300头，有162份查到有寄生虫感染，感染率为54.00%。其中，查出线虫阳性猪54头，平均感染率为36.00%；吸虫阳性猪21头，平均感染率为14.00%；球虫阳性猪68头，平均感染率为45.33%。通过对比分析，发现各生长阶段的猪均存在不同程度的寄生虫感染，其中球虫感染率最高，感染最普遍；冬春两季寄生虫感染差异显著。%To understand the situation of gastrointestinal parasites infection of a large-scale pig farm by isolating eggs or larvae from pig faeces,the investigations were conducted in pigs’ digestive tract in spring and autumn on large-scale pig farms in the Suzhou region. The results showed that,among 300 pigs in two round detections,162 pigs were infected with parasites at the rate of 54.00%,with 54 nematode-positive pigs at the average infection rate of 36.00%,with 21 paragonimus-positive pigs at the average infection rate of 14.00%,and with 68 coccidia-positive ones at the average infection rate of 45.33%. Comparative analysis showed that pigs in every growth phase were infected with parasites in varying degrees. Among them,tenella infection were the highest and the most prevalent. Moreover,parasitic infections in spring and winter turned out to be significantly different.
