摘　　要：为研究乌审旗地区绵羊主要蠕虫病流行病学,以及进一步筛选对优势虫种具有较强驱虫效果的药物,本研究以乌审旗不同苏木镇为试验点,随机采集绵羊新鲜粪便,采用漂浮法、沉淀法和改良麦克马斯特计数法对消化道蠕虫虫卵进行定性与定量检查,从而掌握本地区绵羊蠕虫病流行情况和优势虫种。在此基础上,选取一定数量的捻转血矛线虫感染率较严重(EPG≥500)的绵羊,给予不同驱虫药,进行驱虫效果对比试验。结果表明,乌审旗地区绵羊消化道寄生虫总感染率为51.42%,其中线虫感染率为44.05%,绦虫感染率为10.76%。对比试验结果表明,氯氢碘柳氨钠注射液、阿维菌素氯氢碘柳氨钠片复方制剂和硝碘酚腈注射液均显示出强大的驱虫效果,尤其对胃捻转血矛线虫的驱杀作用更为突出,而盐酸左旋咪唑片的驱虫效果较差。因此,乌审旗地区绵羊消化道线虫感染率由以前的84%左右显著下降至44%左右,但仍比较严重。硝碘酚腈和氯氰碘柳胺钠能够彻底驱杀目前流行的优势虫种-胃捻转血矛线虫,而左旋咪唑的效果却较差。In order to study the epidemiology of the main helminthiasis,and further screen the drugs with a strong anthelmintic effect on the dominant species of nematodes in Uxin Banner.Different Sumu towns were selected as the experimental sites to randomly collect fresh sheep feces.The floating method,the sedimentation method,and the modified McMaster test method were used to qualitatively and quantitatively check the worm eggs of the digestive tract,so as to obtain the epidemic situation and dominant species of sheep worms in the region.On this basis,a certain number of sheep with a higher infection rate of Hemonchus contortus(EPG ≥ 500) were selected,and different anthelmintics were given to compare the anthelmintic effects.The results showed that the total infection rate of digestive tract parasites in Uxin Banner was 51.42%,among which the nematode infection rate was 44.05% and the cestodes infection rate was 10.76%.The results of the comparative tests showed that the chlorohydrin iodide sodium injection,avermectin chlorohydrin iodide sodium compound preparation,and nitroiodazole injection showed strong anthelmintic effects,especially for the Haemonchus contorted in stomach.The anthelmintic effect of the levamisole hydrochloride tablets was poor.The digestive tract nematodes infection rate in Uxin Banner had decreased significantly from about 84% to around 44%,but it was still serious.Nitroxynil and Closantel Sodium could completely kill the current dominant species,i.e.,the Haemonchus contorted in stomach,but the effect of levamisole was poor.
