Abstract

Half of 8 naturally infected dairy calves were treated with levamisole injectable at 6 mg/kg body-weight. In a 2nd experiment half of 10 more calves received levamisole boluses at different dose levels from 5.4 to 10.2 mg/kg. The remaining animals in both experiments served as untreated controls....

Abstract

Five calves infected with Dictyocaulus viviparus and gastro-intestinal nematodes were treated with cambendazole 45% paste at 40 mg/kg body-weight. Faecal egg counts 6 or 7 days later showed 99 to 100% reductions for each of the various genera present in the 5 controls. None of the calves had...
