两种药物驱除放牧绵羊线虫的效果对比试验

选用伊维菌素注射剂按0.1,0.2,0.3mg/kg剂量和盐酸左旋咪唑片剂7.5,15,22.5mg/kg剂量对放牧绵羊进行驱虫试验,分别于给药后7d、14d检查效果。结果：伊维菌素组第7d消化道线虫的虫卵减少率分别为99.10%,99.18%和99.21%。14d分别为97.18%,98.91%,99.21%;肺线虫幼虫7d无明显变化,14d减少率分别为96.59%,96.51%,97.37%。左旋咪唑组第7d消化道线虫的虫卵减少率分别为67.79%,93.17%和95.52%,14d分别为54.68%,83.62%,84.30%;对肺线虫第7d幼虫减少率分别为62.76%,58.13%和45.74%,14d分别为0、72.76%,83.72%。试验表明伊维菌素注射液驱虫效果明显优于左旋咪唑片剂。

Comparison of Effect of Two Medicine Against Nematode in Grazing Sheep

Ivermectin injection in a dose of 0.1,0.2 and 0.3mg/kg and Levamisole tablet in a dose of 7.5,15 and 22.5mg/kg were used to conduct the deworming test in grazing sheep. The effect was checked after administer 7d and 14d,resp.The results showed that the reduetive rate of eggs in alimentary canal of sheep in Ivermectin groups after administer 7d were 99.10%,99.18% and 99.21%. but were 96.59%,96.51% and 97.37% after administer 14d.the reduetlve rate of larvae of lung nematode had not obviously change after administer 7d,but were 96.59%,96.51% and 97.37% after administer 14d.The reductive rate of eggs in alimentary canal of sheep in Levamisole groups after administer 7d were 67.79%,93.17% and 95.52%, but were 54.68%,83.62% and 84.30% after administer 14d.The reductive rate larvae of lung nematode after administer 7d were 62.76%,58.13% and 45.74% but were 0,72.76% and 83.72% after administer 14d.The test proved that the effect of Ivermectin injection for deworming was more than that of Levamisole tablet
