Abstract

The efficacy of doramectin (200 mg/kg) against intestinal nematodes in 10 Nelore heifers was studied; 10 further cattle served as untreated controls. From days 14 to 18 after treatment 2 animals from each group were necropsied and examined for nematodes. The results showed that the treatment was...
