摘　　要：通过对天祝县感染了牛皮蝇的牦牛的药物实验,确定了伊维菌素注射剂与浇泼剂在防治该病时的最低剂量。将280头牦牛随机分成7组,1~3组分别在颈部皮下注射0.1%伊维菌素注射液1μg/kg,5μg/kg和10μg/kg,4~6组分别沿背中线浇泼0.5%伊维菌素浇泼剂25μg/kg、50μg/kg和250μg/kg,将第7组设为空白对照。对前6组在11月份统一治疗。在第2年的3月份和5月份检查试验牦牛的背部瘤包,在治疗组牛的背部未发现瘤包,但在对照组牛的背部发现了三期幼虫。结果表明：1μg/kg伊维菌素注射剂和25μg/kg的浇泼剂对自然感染的牛皮蝇幼虫有较好的防治效果。Medicine experiment was carried out on yak infectious with warble flies in Tianzhu county,the lowest dosage of Ivermectin injection or watering was determined.280 yak was divided into 7 groups randomly,group I,group II,group III injected in neck with 0.1% Ivermectin 1 μg/kg,5 μg/kg and 10 μg/kg,group IV,group V,group VI watered with 0.5% Ivermectin 25 μg/kg,50 μg/kg and 250 μg/kg along back median line,group Ⅶ was blank control.From group I to group VI was cured in November.In March and May in the second year,yak back tumor was detected.No tumor was found in cure group,however,in control group,it was found on the back.The results showed that 1 μg/kg Ivermectin injection and 25 μg/kg Ivermectin watering showed better cure rate for yak natural infection of warble flies.
