There were selected 20 calves, crossbred Gir and Dutch breeds and male, also divided into two groups. Animals of the control group received no treatment, while the treated animals were given the formulation in the volume of 1ml / 10kg per body weight, being administered pour-on which correspond the dose of 600mcg of abamectin and 3mg fluazuron. 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 the means of 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 product showed an efficacy test results 90.70% and 96.84% respectively for the experimental days. Abamectin 0.6% association with 3% fluazuron was effective in controlling D. hominis in naturally infected cattle.
