A controlled anthelmintic trial was conducted to determine the efficacy of febantel paste (45.5%) at dosages of 2.5, 5.0, 7.5, and 10.0 mg/kg in calves harboring natural gastrointestinal nematode infections. Dosages of 5.0, 7.5 and 10.0 mg of febantel/kg of body weight were greater than 96% effective in removing adults of Haemonchus contortus, Ostertagia spp, Cooperia spp, and Oesophagostomum radiatum. The 2.5 mg/kg dosage was considered suboptimal because of low efficacy against Ostertagia and Cooperia spp. Efficacies against Trichostronglylus axei, Trichuris spp, Bunostomum phlebotomum, and Stronglyloides papillosus were difficult to determine because fewer numbers of these nematodes were recovered. Efficacies of febantel paste against immature bovine parasites ranged from 83.62% to 97.72%.
进行了一项对照驱虫试验，以确定在自然感染胃肠道线虫的犊牛中，按2.5、5.0、7.5和10.0毫克/千克剂量使用非班太尔膏剂（45.5%）的疗效。按5.0、7.5和10.0毫克非班太尔/千克体重的剂量，对捻转血矛线虫、奥斯特他线虫属、古柏线虫属和辐射食道口线虫成虫的驱虫效果超过96%。2.5毫克/千克的剂量被认为不是最佳剂量，因为对奥斯特他线虫属和古柏线虫属的疗效较低。由于回收的这些线虫数量较少，难以确定对雅致毛圆线虫、毛首线虫属、牛血矛线虫和类圆线虫的疗效。非班太尔膏剂对未成熟牛寄生虫的疗效为83.62%至97.72%。
