Abstract

Calves were experimentally infected with 6 species of gastro-intestinal nematodes and treated 35 days later with albendazole orally at 2.5, 5.0 or 7.5 mg/kg body-weight. Post-mortem worm counts 7 days after treatment showed that at the lowest dose level 99.3% of Trichostrongylus axei, 99.0 of...

Abstract

Calves were artificially infected at 6 weeks of age with 7 species of gastro-intestinal nematodes and, 35 days later, were treated orally with avermectin B1a at 50, 100 or 200 mu g/kg body-weight or were left untreated. At postmortem examination 7 days after treatment the 3 doses were found to have ...

Abstract

Six-month-old calves were experimentally infected with 8 species of nematodes and treated subcutaneously with ivermectin (200 mu g/kg body-weight) when the worms were immature (17 days after infection) or mature (38 days). The 10 untreated controls had a geometric mean of 20 037 nematodes at...
