四川省西昌市规模猪场寄生虫调查研究

Investigation on Parasites of Swine Status in Xichang

为了解西昌市规模猪场寄生虫的感染情况,试验采用饱和食盐水漂浮法和沉淀法调查了西昌市3个猪场共92个样本。结果表明:3个猪场都有寄生虫感染,感染率为29.3%,感染率最高的猪场为47.1%;不同年龄的猪都有感染,其中仔猪的感染率为35.3%,哺乳母猪的感染率为30.8%,基础母猪的感染率为30.2%,育肥母猪的感染率为21.1%;共发现3种线虫,分别是蛔虫(检出率为13.0%)、球首线虫(检出率为16.3%)和食道口线虫(检出率为2.2%)。说明西昌市猪寄生虫感染主要是线虫感染,应针对该病防治。

To understand the infections of swine parasites in Xichang, 92 fecal samples which were randomly obtained from three pig farms, were examined by using the saturated sodium chloride flotation method and precipitation method to determine the situation of parasites infections in Xichang. The results showed that there are parasites infections in the three pig farms, in which the mean infection rate was 29.3%, and the highest infection rate was 47.1% in the pig farm; there are infections in the pigs at different ages, and the infection rates of piglets, nursing sows, sows and fat pigs were 35.3%,30.8%, 30.2% and 21.1%, respectively. Three species of parasites were identified as followed: ascaris suum(13.0% of detection rate), pig first nematodes(16.3% of detection rate) and pig nodular worm(2.2% of detection rate). It is concluded that swine parasites are mainly nematode infection, suggesting that it should be paid attention to the prevention and control of the disease.
