The anthelmintic activity of cambendazole in calves and lambs.
Tests were carried out on the efficacy of Cambendazole (5-isopropoxy carbonylamino-2-(4-thiazolyl) benzimidazole) against lungworm and gastrointestinal parasites of calves and lambs. Against Dictyocaulus viviparus the compound was highly effective (80%) against mature worms at levels of 35 mg/kg and over and immature "arrested" worms at 60 mg/kg (71% efective). In the Calves the compound was very effective (90 to 99%) against adult Haemonchus placei, Ostertagia spp., Trichostrongylus axei and Cooperia oncophora at all levels tested (15, 20, 25, 30, 40 and 60 mg/kg). Against adult Nematodirus spp. dosages of 30, 40 and 60 mg/kg were 81%, 94% and 99% effective respectivelyAgainst arrested Ostertagia spp. larvae, a dosage of 60 mg/kg was 90% effective. Immature stages of Cooperia spp. were susceptible at all levels used but those of Nematodirus spp. required levels of 60 mg/kg for 99% removal. In the lambs the compound was highly effective against immature and mature nematodes when given orally at all levels tested from 15 mg/kg to 30 mg/kg. Significant reductions (81%) in Moniezia expansa scolices were also observed at dosages from 15 mg/kg to 30 mg/kg.
