Spirulina Supplementation to the Semen Extender Influences the Quality and Antioxidant Parameters of Chilled or Cryopreserved Arabian Stallion Spermatozoa.
Abstract: The present study attempted to investigate the effect of various concentrations of spirulina platensis additions to the semen extender on Arabian stallion spermatozoa quality. Semen samples were collected with artificial vagina from five fertile stallions and diluted with an extender containing spirulina (2, 4, 6, and 8 mg/100 mL) or without spirulina (control). Aliquots of diluted semen were cooled (5°C, 90 minutes) and frozen (-196°C, 7 days), then physical traits of thawed spermatozoa were examined. Furthermore, antioxidant activities of superoxide dismutase (SOD), glutathione reductase (GSR), total antioxidant capacity (TAC), and malondialdehyde (MDA) were measured in post-cooling and freezing spermatozoa. The results indicated that spirulina supplemented with the extender had no effect (P >.05) on sperm quality parameters and antioxidant activities after cooling. However, adding 6 mg spirulina/100 mL to the freezing extender improved (P < .05) the speed parameters and total motility percentage of frozen/thawed spermatozoa. Besides, supplementation of freezing extender with the previous level increased (P < .05) TAC, SOD and GSR concentrations/activities (0.86 ± 0.32 mM/L, 323.70 ± 12.81 U/mL, and 38.65 ± 1.90 U/mL, respectively) compared with the control (0.70 ± 0.25 mM/L, 165.80 ± 8.12 U/mL, and 25.70 ± 1.83 U/mL, respectively). While, lipid peroxidation of the frozen-thawed semen was reduced (P < .05, 17.97 ± 1.30 µmol/ L) compared with the control (29.39 ± 1.89 µmol/ L). Accordingly, the present results revealed that additions of 6 mg spirulina/100 mL to the freezing extender improved semen quality and reduced cryodamage of the Arabian stallion spermatozoa.

This research investigates how adding different doses of spirulina platensis to an extender that preserves horse semen affects the quality of the sperm. The study concluded that a specific concentration of spirulina in the mixture improves the speed and total motility percentage of the frozen and then thawed sperm, and also boosts antioxidant activity, thus improving the semen’s quality and reducing the cryodamage.
Methodology
- Semen samples were collected from five fertile Arabian stallions using an artificial vagina.
- The semen was then diluted with an ‘extender’, a preserving solution, either containing spirulina (2, 4, 6, or 8mg/100mL) or without spirulina as a control.
- The diluted semen was cooled (5°C, 90 minutes) and then frozen (-196°C, 7 days).
- Physical traits of the sperm that had been thawed from the deep freeze were then examined for quality parameters.
- Additionally, the antioxidant activities of superoxide dismutase (SOD), glutathione reductase (GSR), total antioxidant capacity (TAC), and malondialdehyde (MDA) were measured after the semen had been cooled and frozen.
Findings
- The study found that, after cooling, the use of an extender supplemented with spirulina had no discernible effect on sperm quality parameters or antioxidant activities.
- However, when 6mg spirulina/100mL of extender was used to freeze the semen, the study found that the speed parameters and total movement of the frozen and then thawed sperm were improved.
- The same concentration of spirulina also increased the level of TAC, SOD and GSR – signaling enhanced antioxidant activity.
- Lipid peroxidation of the frozen-thawed semen, which can indicate cell damage, was reduced in the sample group where the extender had been supplemented with spirulina.
Conclusion
- The researchers concluded that adding 6mg spirulina/100mL to the extender used to freeze horse semen improved overall semen quality.
- This dosage of spirulina also reduced the ‘cryodamage’ – cell damage that can occur during the freezing and warming process.
