We selected 20 calves, crossbred Gir and Holstein breed, male and female, separated into two groups, control and treated. The control group of animals received no treatment, while the animals of the treated group received eprinomectin formulation of 1% at a single dose of 1 mL/50 kg body weight (200mcg of eprinomectin/kg) per injectable route. On days +7 and +14 a count of the total number of live larvae of D. hominis on both sides of the animal for the purpose of evaluation of the effectiveness was performed. Statistical analysis of average living larvae of D. hominis counted among the groups, control and treated, showed that there was a significant difference (p ≤ 0.05) between groups on days +7 and +14. The investigational product showed an efficacy of 100% results in both experimental days. The injectable eprinomectin 1%, shown to be effective in cattle naturally infested by D. hominis (the human bot fly).
