“害获灭”(Ivomec)对牦牛消化道线虫和肺线虫的驱除试验

An Experiment of Driving Out Gastrointestinal and Lung Nematode in the Yak with Ivomec

我们于1990年4月—11月在国内首次用“害获灭”对28头牦牛的消化道线虫和肺线虫进行了驱除试验。结果表明,“害获灭”按每公斤体重150、175、200微克颈部皮下注射,对牛仰口线虫 B.Phlebotomum 的驱虫率为90.1、100、100%,对叶氏夏伯特线虫C.erschowi 为78、100、100%,对辐射结节虫 O.radiatum 为94.3、100、100%,对球形毛首线虫 T.globulosa 为93.0、97.3、97.3%,对美丽筒线虫 G.pulchrum 为83.0、100100%,对胎生网尾线虫 D.viviparus 为100、100、100%,用200微克时对兰氏毛首线虫的驱虫率为93.3%。由此看出,“害获灭”按每公斤体重175、200微克对牦牛上述消化道线虫和肺线虫均有良好的驱除效果,且用量小、给药方便,无副作用,宜于在牧区推广使用。

The experiment of driving out gastrointestinal and lung nematode in 28 Yaks with vomec was performed.The results showed that,when this drug were injected via ypoderm in doses of 150μg,175μg and 200μg/per kg of body weight,respectively,the xpellant rate were 91.0,100 and 100% for B.phlebotomun;78.0,100 and 100% for C.erschowi;94.3,100,100% for O.radiatum;93.0,97.3,97.3% for T.globulosa;83.0,100, and 100% for G.pulchrum,and it was all 100% for D.viviparus.When this drug was in- jected in a dose of 200μg/kg of body weight,the expellent rate was 93.3%.These data re- veal that Ivomec has a good effect of driving out Nemotode in the Yak mentioned above. The dose is minute,and the administration is convenient.In addition,it has no side effect. Therefore,it could be applicated and disseminated in pastoral area.
