【摘要】：为了解广西南宁地区规模化猪场和散养户猪群肠道寄生虫的流行情况,本研究采用涂片法、水洗沉淀法、饱和盐水漂浮法、尼龙筛淘洗法、卢氏碘液染色法等对该地区8个猪场不同生长阶段的猪群480份粪源样品进行检测。结果显示,南宁地区猪肠道寄生虫感染主要有猪蛔虫、猪球虫、姜片吸虫、食道口线虫和鞭虫,其中蛔虫的感染率最高(77.7%),其次是球虫(58.9%),鞭虫、姜片吸虫、食道口线虫感染率分别为11.2%、9.5%、8.5%;散养户猪群总感染率为47.7%,高于规模场感染率(31.0%);同时,在生长阶段中日龄越大的猪群感染率越高,感染的寄生虫种类也越多,其中,母猪感染率达21.9%,其次是育肥猪和保育猪,感染率分别为21.4%、20.2%,哺乳仔猪感染率为15.2%;猪群多重感染情况以蛔虫和球虫同时感染为主,感染率达28.5%,散养户猪群多重感染率略高于规模场,特别是蛔虫、球虫和姜片吸虫的三重感染率显著高于规模场;各生长阶段中,以母猪和育肥猪多重感染率较高,哺乳仔猪的多重感染率最低。本次调查结果为广西南宁地区科学驱虫程序提供指导,为寄生虫病的防治提供数据依据。
[Abstract]:In order to understand the prevalence of intestinal parasites in large-scale pig farms and free-range hogs in Nanning, Guangxi, the methods of smear, water washing and precipitation, saturated brine floating, nylon sieve washing were used in this study. Four hundred and eighty fecal samples from different growth stages of 8 pig farms in this area were detected by Lushi iodine solution staining method. The results showed that the main infection rates of intestinal parasites in Nanning were Ascaris lumbricoides, coccidia suis, Trichuris gingeracea, oesophagus nematode and Trichuris. The infection rate of Ascaris lumbricoides was the highest (77.7%), followed by 58.9% of coccidia, 58.9% of Trichuris, and 77.9% of Trichuria curcuma. The infection rate of oesophagus nematodes was 11.2and 9.55.The total infection rate of the scattered family pigs was 47.7, which was higher than that of the field infection rate of 31.0%. At the same time, the higher the infection rate of the pigs of the older the day in the growth stage, the more kinds of parasites were infected, among which, The infection rate of sows was 21.9, followed by fattening pigs and nurtured pigs, with the infection rates of 21.40.2and 15.2respectively. The multiple infection rate of pigs was mainly infected by Ascaris and coccidiosis, and the infection rate was 28.50.The infection rate of multi-weight pig herd was a little higher than that of scale farm, and the infection rate of fattening pigs was a little higher than that of breast-feeding piglets. Especially, the triple infection rate of Ascaris lumbricoides, coccidia and paragonimiasis was significantly higher than that of scale field, and the multiple infection rate of sows and fattening pigs was higher than that of breast-feeding piglets. The results of this investigation provide guidance for the scientific deworming program in Nanning, Guangxi, and provide data basis for the prevention and control of parasitic diseases.
