江苏省苏中地区规模化猪场肠道寄生虫感染情况调查
|
摘要
为了解江苏省苏中地区规模化猪场肠道寄生虫的感染情况,从该地区15个规模化养猪场随机采集了895份粪便样品,采用水洗沉淀法、饱和盐水漂浮法和卢戈氏碘液染色镜检法对样品进行了检查。结果:肠道寄生虫的总感染率为15. 08%,主要感染虫种包括球虫、食道口线虫、毛首线虫、蛔虫和结肠小袋纤毛虫。其中结肠小袋纤毛虫、蛔虫和球虫的感染率较高,分别为5. 81%、4. 47%和3. 35%。保育猪和种公猪的肠道寄生虫感染率显著高于其他生产阶段,仔猪的感染率最低。
In order to understand the infection situation of intestinal parasites in large-scale pig farms in the mid-Jiangsu Province area,895 fecal samples were collected randomly from 15 large-scale pig farms in this area. The fecal samples were examined by washing and precipitation,saturated salt water floatation and Lugol iodine staining. The results were that the total infection rate of intestinal parasites was 15. 08%. The main infectious species were coccidia,Oesophagostomum,Trichuris suis,Ascaris Iumbricoides and Balantidium coli. The infection rates of Balantidium coli (5. 81%),Ascaris Iumbricoides (4. 47%) and coccidian (3. 35%) were higher than those of other species.The infection rates of intestinal parasites in weaning piglets and sows were significantly higher than that in pigs in the other production stages,and the infection rate in piglets was the lowest.
