Resumo
The aim was to evaluate the effects of the addition of antimicrobials to the diluent for the cryopreservation of the semen of collectors, especially on the morphofunctional parameters. Ten ejaculates from adult males were obtained by electroejaculation. The samples were evaluated for volume, concentration, motility, morphology, membrane functionality, sperm viability, mitochondrial activity and binding capacity. Subsequently, they were cryopreserved in Tris with egg yolk (20%) and glycerol (3%) added or not (control) with gentamicin (70µg/mL), or with the penicillin (1000 IU/mL) + streptomycin (1mgE/mL). After one week, the samples were thawed and evaluated according to the fresh semen. As for the results, no significant differences were observed between the control treatment and those added with antimicrobials, emphasizing that these do not damage the sperm morphofunctional parameters during cryopreservation. In this sense, it is suggested that both gentamicin and the penicillin/streptomycin combination could be added to the extender for the cryopreservation of the collared peccary semen.
