摘 要：
【目的】摸清广西区规模化猪场和散养户猪群肠道寄生虫的流行情况,旨在为养殖户提供预防及控制猪寄生虫病的科学依据。【方法】通过直接涂片法、沉淀法、尼龙筛淘洗法、卢氏碘液染色法、蔗糖溶液漂浮法等对广西12个市的规模化猪场和散养户猪群共3021份样品进行肠道寄生虫感染情况调查。【结果】广西猪群感染的肠道寄生虫主要有猪球虫、小袋纤毛虫、线虫和隐孢子虫,小袋纤毛虫和猪球虫的感染虽然比较普遍,但感染强度均较低,属于正常带虫现象。广西规模化猪场中线虫感染率最高的是类圆线虫(2.26%),其次是鞭虫(0.98%)和蛔虫(0.81%),食道口线虫最低(0.58%);在广西散养户猪群中,线虫感染率最高的是蛔虫和鞭虫,均为8.19%,最低是食道口线虫(4.56%)。0~6月龄猪群中各种线虫的感染率随着日龄的增长而增长,但6月龄以后,线虫感染率在规模化场猪趋于平缓,散养户猪群则明显下降。【结论】广西猪群仍然存在寄生虫感染的危害,其中线虫的优势虫种是猪蛔虫和鞭虫,即广西当前甚至未来几年内,猪群需要重点防范的体内寄生线虫仍是蛔虫和鞭虫。

摘 要：
【Objective】 The intestinal parasite prevalence of swinery from large-scale pig farms and free-ranging farmers in Guangxi was investigated to provide scientific evidence for farmers to prevent and control parasitic disease.【Method】 Using direct smear method,precipitation method,nylon sieve washing method,Lugol's iodine staining method,and sucrose solution method of floating,totally 3021 samples from large-scale pig farms and free-ranging farmers in 12 cities of Guangxi were detected.【Result】 The results showed that intestinal parasites infected swinery in Guangxi were mainly Eimeria spp,Balantidium coli,nematode and Cryptosporidium spp,which had low infection rate,consequently it was normal situation.In the large-scale pig farm,the infection rate sequence was Strongyloididae(2.26%)> whipworm(0.98%)> roundworm(0.81%) > Oesophagostomum(0.58%),while for free-ranging farmers,it was roundworm and whipworm(8.19%) > Oesophagostomum(4.56%).Infection rates of the pigs 0-6 months old rose along with the time.Six months later,the infection rate in large-scale pig farms leveled,but it dramatically dropped in farmers' rang.【Conclusion】 The dominant species of intestinal parasites in parasitic infection of Guangxi swinery population were Ascaris suum and Trichuris suis,as a result,regarding swinery management,the major focus will still be Ascaris suum and Trichuris suis in the following few years.
