摘　　要：为评价牦牛主要寄生虫病高效低残留防治技术的示范应用效果,按埃普利诺菌素注射剂0.2 mg/kg体重剂量进行规模防治技术示范,通过粪便虫卵检查法和体外寄生虫检查法评估给药后的防治效果,通过牦牛体重、成活率等指标评估防治效益。结果表明,防治给药后7、14、35、151 d,牦牛消化道线虫虫卵转阴率分别为100%、100%、100%和80%,减少率分别为100%、100%、100%和91.5%;防治给药后7、14、35、151 d,原圆科线虫幼虫转阴率分别为83.3%、100%、100%和80%,减少率分别为93.7%、100%、100%和87.2%;防治示范后第7、14、35、151 d,对寄生于牦牛的牛颚虱的杀灭率均达100%;示范应用剂量对牦牛使用安全,防治技术示范群比未防治对照群的牦牛平均多增重8.26±2.13 kg/头,幼年牦牛成活率提高了2.83%。可见该防治技术对牦牛主要寄生虫病具有高效、安全、低残留的防治效果,效益显著。To evaluate the demonstration application effect of efficient and low residue parasitic disease preven⁃tion and control technology on the main parasitic diseases of yaks,Eprinomectin injection was used at a dose of 0.2 mg/kg of body weight.The prevention and control effect were checked and the impact on yak weight and sur⁃vival rate were assessed.Result:At 7,14,35,and 151 day after treatment,the negative conversion rates of nema⁃tode eggs in the digestive tract of yaks were 100.0%,100.0%,100.0%,and 80.0%,respectively,and the re⁃duction rates were 100.0%,100.0%,100.0%,and 91.5%,respectively.At 7,14,35,and 151 day after treat⁃ment,the conversion rates of Protostrongylidae larvae to negative were 83.3%,100.0%,100.0%,and 80.0%,respectively,and the reduction rates were 93.7%,100.0%,100.0%,and 87.2%,respectively.On the 7th,14th,35th,and 151st day after treatment,the killing rate of Linognathus vituli on yaks reached 100%.The dose of 0.2 mg/kg of Eprinomectin injection used in demonstration was safe for yak.Compared to the control group without treatment,the demonstration group increased the average weight 8.26±2.13 kg of 2-year-old yak,and the survival rate of young yaks increased by 2.83%.The results indicate that the prevention and control technology is more effi⁃cient,safe,and low residue for the main parasitic diseases in yaks,with significant benefits.
