• Resumen

  • C-phycocyanin (C-PC) is a biocompound extracted from Arthrospira max-ima. It is a chromophore-protein complex, with antioxidant properties. Its ability to prevent oxidative stress allows for diverse medical applications. This study evaluates the use of C-PC as a protein supplement and an antioxidant for in-vitro sperm preservation in a short-term extender. Viability, progressive motility, DNA damage and percentage of reactive oxygen species where as-sessed in Swine (Sus scrofa domesticus) spermstored for up to 72 hours at 4 °C. Treatments with C-PC had the following concentrations: 0, 34.5, 69, 138 and 207 μg mL−1. Progressive motility and percentage of sperm with undamaged DNA were unchanged (20%) after storage for 48 hours using the 138 ug mL-1 C-PC concentration.
