Resumen
The present study examined the effect of adding the antioxidants vitamins C and E on the quality of semen cryopreserved of curimba (Prochilodus lineatus). Semen samples from nine breeding males were collected for analysis of rate (%) and duration (s) of sperm motility. The sperm pool was diluted into three cryoprotective solutions: Solution A: 5 gr. Beltsville Thawing Solution (BTS) added with 5 mL dimethyl sulfoxide (DMSO) and distilled water to 100 mL; Solution B: Solution A + 0.0001 mg vitamin E; Solution C: Solution A + 0.0001 mg vitamin C. The vitamins C and E were not toxic to the semen of curimba. The sperm motility did not present any significant difference. However, the semen cryopreserved with vitamin C had a longer duration of the motility after thawing. Therefore, the vitamin C is recommended for the cryopreservation of the semen of curimba.
