摘要
为对自然感染牛皮蝇蛆病的黄牛用爱普瑞克制剂进行驱虫疗效观察,本试验设爱普瑞克Ⅰ、Ⅱ、Ⅲ号注射液7个组,空白对照1个组,依据黄牛胸围和体长,按通常采用的黄牛体重估计公式,估算每头牛的体重,皮下注射药物。结果表明:Ⅰ号制剂剂量0.5mg/kg、1.0mg/kg、1.5mg/kg,Ⅱ号制剂剂量1.0mg/kg,Ⅲ号制剂剂量1.0mg/kg,注药后第30d全部瘤疱隆起消失,牛恢复健康。结论为爱普瑞克制剂剂量在1.0mg/kg以上或爱普瑞克Ⅰ号、Ⅲ号注射液剂量在0.5mg/kg时,驱治牛皮蝇蛆病效果极好,但爱普瑞克Ⅱ号注射液剂量0.5mg/kg,治疗牛皮蝇蛆病效果欠佳。

Resuh： In thc 5 groups of the three different does＇ （0.Smg/kg, 1.0mg/kg and 1.Smg/kg ） groups of the Ⅰ forma＇s; the Ⅱ forma （1.0mg/kg） group and the Ⅲ forma （1.0mg/kg） group, the blocks of swelling mass that was induced hy the 3rd larva of Hypodcrma boris disappeared. These cattle brought back to health. Conclusion： They are very good that the eprinomectin＇s does above 1.0mg/kg or the 0.5mg/kg dose of the test＇s forma Ⅰ and Ⅱ killed the 3rd larva of ttypoderma boris.
