伊维菌素对放牧山羊消化道线虫的驱治试验

Experiment of Ivermection Expelling Digestive Tract Nema in Grazing Goats

验证放牧条件下伊维菌素驱虫效果,从饲养管理、放牧条件相同的一群300多只羔羊中通过粪便检查、称重从中选出体重相差不大、感染消化道线虫较为严重60只,根据感染程度均匀搭配,分为三组进行试验,每组20只用伊维菌素预混剂拌料饲喂放牧山羊,试验结果是试验组、药物对照组驱虫后3 d虫卵减少率分别是96.4%和88.7%,虫卵转阴率分别为80%和25%;驱虫后10d两组羊的虫卵减少率分别为100%和97.8%,虫卵转阴率分别为100%和85%,伊维菌素对放牧山羊消化道线虫驱虫效果优于药物左旋咪唑。

The objective of this study was to test the expelling effects of Ivermectin.Sixty seriously infected with tract nema lambs were selected from 300 lambs which had similar weight,management and pasturing condition through fecal examination and weighing.The infection degree was used to match experimental groups.Twenty lambs in each group were fed with Ivermectin premix feed.The results indicated that for experimental group and drug control group,reduction rates of egg were 96.4% and 88.7%,egg negative rates were 100% and 85%,respectively.The effects of Ivermectin expelling digestive tract nema was better than Levamisole.
