Anthelmintic efficacy of ivermectin against Mecistocirrus digitatus was evaluated in 10 naturally infected zebu calves. Group 1 (n = 5) was not treated, and group 2 (n = 5) was treated SC with 200 micrograms of ivermectin/kg of body weight. Calves were euthanatized 14 or 15 days after treatment. There was 100% overall reduction of M digitatus in treated calves, which was significant (P = 0.0079) compared with reduction in controls. Cooperia punctata, Haemonchus similis, and Trichostrongylus axei were found in controls. Efficacy against these parasites in treated calves was 100%.
在10头自然感染指形长刺线虫的瘤牛犊中评估了伊维菌素对指形长刺线虫的驱虫效果。第1组（n = 5）未接受治疗，第2组（n = 5）以200微克伊维菌素/千克体重的剂量皮下注射治疗。治疗后14或15天对犊牛实施安乐死。治疗后的犊牛体内指形长刺线虫总体减少了100%，与对照组相比差异显著（P = 0.0079）。在对照组中发现了点状库珀线虫、似血矛线虫和艾氏毛圆线虫。治疗后的犊牛对这些寄生虫的驱虫效果为100%。
