摘 要：
选择6~8月龄自然感染消化道线虫和肺线虫的牦牛100头,按寄生虫感染情况搭配分为5组,每组20头,1~3组牦牛分别按0.1,0.2和0.3 mg/kg.b w剂量皮下一次注射埃普利诺菌素注射剂,4组为药物对照组,按0.2 mg/kg剂量皮下注射伊维菌素注射剂,5组为阳性对照组,不给药。结果表明:埃普利诺菌注射剂0.2 mg/kg剂量对消化道线虫(除毛首线虫外)的虫卵转阴率、减少率分别达90.0%和95.0%;对网尾线虫幼虫转阴率、减少率均达100.0%;对原圆科线虫幼虫转阴率、减少率分别达90.0%和92.5%;对线虫成虫、寄生阶段幼虫的总计驱虫率分别达97.8%和94.9%;0.3 mg/kg剂量对消化道线虫(除毛首线虫外)的虫卵转阴率、减少率均达100.0%,;对网尾线虫幼虫转阴率、减少率均达100.0%;对原圆科线虫幼虫转阴率、减少率分别达95.0%和97.5%;对线虫成虫、寄生阶段幼虫的总计驱虫率分别达99.3%和97.7%;0.1 mg/kg剂量对线虫虫卵(幼虫)的转阴率、减少率、驱虫率均低于0.2,0.3 mg/kg剂量组;对照药物伊维菌素注射剂、0.2 mg/kg剂量组对线虫的驱虫效果略低于同剂量埃普利诺菌素注射剂组;埃普利诺菌注射剂3个剂量组试验牦牛未见异常反应。试验证明埃普利诺菌注射剂0.1,0.2,0.3 mg/kg体重剂量驱除牦牛线虫安全有效。其中以0.2 mg/kg体重剂量经济高效。

摘 要：
100 yaks with aged from 6 to8 month, nematodes naturally infected gastrointestinal and lungworm were selected, divided into 5 groups according to the parasite infections, each group include 20 yaks, 1 ~ 3 groups of yak at 0.1, 0.2, and 0.3 mg/kg) b w dose,a subcutaneous injection of eppley rhzomorph respectively, 4 groups for drug control at 0.2 mg/kg dose of subcutaneous injection of ivermectin,5 groups is as the positive control group without administration. The results showed that the rate of turning negative, loss of nematodes in gastrointestinal at 0.2 mg/kg dose of ppley's bacteria injection reach 90.0% and 95% respectively, reach 100.0% for nematode larvae. reach 90.0% and 92.5% respectively for original nematode larvae. The total insecticide rate of larvae was 97.8% and 94.9% respectively in parasitic stage for adult larvae. The rate of turning negative, loss of nematodes in gastrointestinal at 0.3 mg/kg dose reach 100.0%,reach 100.0% for tail nematode larvae, reach 95.0% and 97.5% respectively for original nematode larvae. The total insecticide rate of larvae was 99.3% and 97.7% respectively in parasitic stage for adult larvae.(The rate of turning negative, loss of nematodes,repellent rate at0.1 mg/kg dose is low comparied with 0.2, 0.3 mg/kg dose group. The repellent effect of controlled drug of ivermectin injection, at 0.2 mg/kg dose is slightly lower than applying samedose of eppley rhzomorph injection It indicated that eppley injection at 0.1, 0.2, 0.3 mg/kg body weight dose is effective and safe for yaks. 0.2 mg/kg body weight dose is optimum.
