Resumo

This study evaluated the effects of dietary organic selenium (Se) on viability of chilled boar semen. Twelve boars were divided into three groups: control (CON), 0.3mgkg(-1) sodium selenite; inorganic (INO), 0.5mgkg(-1) sodium selenite and organic (ORG), 0.5mgkg(-1) Se yeast. The experiment was conducted within 10weeks, and analysis was performed fortnightly, in storage semen by 72h. No effect was observed on motility; however, straightness and linearity percentages were higher (P<0.05) in the animals receiving CON diet compared with INO group. Percentages of cells with both plasma and acrosomal intact membranes, lipidic membrane peroxidation and mitochondrial membrane potential were similar on all treatments. Animals receiving CON diet presented higher (P<0.05) values of ATP when compared with INO group. The PHGPx was higher (P<0.05) in animals that received ORG in comparison with INO group. In conclusion, organic selenium supplementation increases PHGPx but does not improve chilled semen viability in 72h. (AU)
