藏羊狂蝇蛆驱杀试验效果观察

Observation on the Effect of Grazing Tibetan Sheep's Wild Fly Maggots

为进一步验证藏羊狂蝇蛆的驱杀效果,于2018年10月和2019年9月,分别对青海省海东市某养殖场的150只藏羊进行驱虫试验,选择使用伊维菌素口服液和阿维菌素透皮剂驱虫,观察2种药物的驱虫效果。看出10月中旬对藏羊进行驱虫,没有取得很好的驱虫效果,伊维菌素驱虫和阿维菌素驱虫的效率分别为60%和40%,整体驱虫效果较差。而9月上旬选择上述2种药物对患病的藏羊进行驱虫处理,驱虫率高达100%。主要与狂蝇蛆的繁殖生长条件有很大联系,因此,在对当地藏羊进行狂蝇蛆驱杀通常选择9月上旬。

In October 2018 and September 2019,deworming tests were conducted on 150 Tibetan sheep in a farm in Haidong,Qinghai Province,to further verify the efficacy of deworming Tibetan sheep maggots,the deworming effects of ivermectin oral liquid and avermectin were observed.The results showed that the deworming efficiency of Tibetan sheep in mid-october was 60%and 40%,respectively.The overall deworming efficiency of ivermectin and avermectin was poor.In the first ten days of September,the above two drugs were selected to treat the infected Tibetan sheep,and the rate of deworming was as high as 100%.It is mainly related to the breeding and growing condition of the Maggot,so the maggot culling of local Tibetan sheep is usually carried out in early September.
