E-mail: jacialmeida01@yahoo.com.br Objectifying evaluate the effects of antiparasitic treatments, used in therapeutic doses in the preventive controls of the natural infestations for Dermatobia hominis (D. hominis) and Haematobia irritans (H .irritans), in the andrological characteristics were used 20 Nelore breeder bulls, managed on pasture of Brachiaria decumbens and Brachiaria brizantha, by six months. The andrological exams were accomplished every 15 days and parasitological exams every 15 and 60 days after the treatments. In the statistical analyses were used Anova and comparisons between averages according to Kruskal-Wallis and Bonferroni tests. The obtained results indicated that the antiparasitic treatments used did not influence negatively the andrological characteristics. The prophylactic application of antiparasitic, before the mating station, is an efficient technique for controls of natural ectoparasitism by D .hominis and H. irritans, not interfering in the seminal quality of the Nelore bulls.
