The prophylactic efficacy of ivermectin against navel or scrotal myiasis in calves was evaluated in eight trials in Argentina and Brazil. In two trials, calves were injected subcutaneously with ivermectin at a dosage of at least 200 microg kg(-1) within 24 h of birth. In the other six trials, two with two-month-old calves and four with four-month-old or older calves, all calves were treated with ivermectin at a dosage of at least 200 microg kg(-1) immediately after castration. In all trials, calves were maintained together on pasture and naturally exposed to Cochliomyia hominivorax. Navel and scrotal wounds were examined for myiasis daily for at least 14 days. Incidence of navel and scrotal myiasis was significantly lower (P < 0.01) in treated calves than in control calves.
在阿根廷和巴西进行的八项试验中，评估了伊维菌素对犊牛肚脐或阴囊蝇蛆病的预防效果。在两项试验中，犊牛在出生后24小时内皮下注射至少200微克/千克的伊维菌素。在其他六项试验中，两项针对两个月大的犊牛，四项针对四个月大或更大的犊牛，所有犊牛在去势后立即接受至少200微克/千克剂量的伊维菌素治疗。在所有试验中，犊牛共同饲养在牧场上，并自然暴露于嗜人瘤蝇。每天检查肚脐和阴囊伤口是否有蝇蛆病，至少检查14天。治疗组犊牛的肚脐和阴囊蝇蛆病发病率显著低于对照组犊牛（P<0.01）。
