dc.description.abstractThe aim of this study was to determine an ozone dosage capable of inducing pro-oxidation, and to verify its action on sperm cells during the process of cooling and cryopreservation of equine semen. In this study, we evaluated the ozone concentrations of 2µg/mL,15µg/mL, 30µg/mL e 60 µg/mL added in equine semen cooling and freezing extenders. Samples were evaluated for sperm kinetics patterns, function of sperm structures and lipid peroxidation. In the experiment, the concentration of 15 µg/mL showed higher total and progressive motility when comparing to control (60.3±3 and 40.7±3.4 vs. 54.9±4 e 35.0±4.4, respectively, P < .05) at M24 of cooling; The concentration of 2 µg/mL showed higher percentage of intact plasma and acrosomal membrane when comparing to control at M24 (51.1±3.6 vs. 46.1±3.9, P < .05), M24 after 30 minutes of incubation (43.4±3.1 versus 32.4±2.6, P <.05). The concentration of 2 µg/mL showed higher percentage of intact plasma and acrosomal membrane (P <.05) comparing to control at moments M0 (43.5±5.0 vs. 36.3±3.5), M30 (41.0±3,7 vs. 35.3±2,9) e M60 (39.0±7.0 vs. 31.4±5.4). Thus, it can be concluded that low doses of ozone can lead to a positive response in the sperm kinetics patterns and sperm structures after sperm storage at low temperatures. Higher concentrations (30 and 60 µg/mL) were harmful in the cooling and cryopreservation of equine semen.en
