A preliminary study on the effects of E-Z Mixin® and EquiPlus® extenders supplemented with Edible Bird’s Nest on the quality of chilled Arabian stallion semen.

Abstract: The aim of this study was to evaluate the effects of adding different concentrations of edible bird's nest (EBN) which is secreted by swiftlet birds (), into EquiPlus® and E-Z Mixin® extenders on the quality of chilled Arabian stallion semen at various storage times (0, 24 and 48 h). Ten ejaculates were collected from five stallions, and diluted using the two extenders containing 0% (control), 0.12%, 0.24% and 0.24% of EBN + seminal plasma (SP). All the diluted semen samples were then cooled and stored at 5 °C, and examined at 0, 24 and 48 h. Sperm kinetic parameters were assessed using computer assisted sperm analysis (CASA) and viability were assessed using Hoechst33342/PI stain. In both extenders, total motility (TM) and progressive motility (PM) were significantly higher at 0.12% and 0.24% compared to 0.24% + SP at 24 and 48 h. At 0.12%, E-Z mixin® treated semen had significantly higher TM and PM than EquiPlus at 24 and 48 h. At 0.12% and 0.24%, average path velocity (VAP), straight-line velocity (VSL) and curvilinear velocity (VCL) were significantly higher in E-Z mixin® treated semen compared to EquiPlus at 24 and 48 h. Comparisons between the two extender types at different concentrations of EBN showed no significant difference in lateral head amplitude (ALH), linearity (LIN), straightness (STR), beat cross frequency (BCF) and viability, irrespective of the storage time. The percentage of viable was significantly higher in E-Z mixin® than EquiPlus® at 0 and 48 h in control and 0.12%. Supplementation of the E-Z mixin extender with 0.12% and 0.24% EBN concentrations in the absence of SP provided better CASA parameters such as TM, PM, VAP, VSL, and VCL at 24 and 48 h storage time. In conclusion, the results of this study indicated that chilled semen from Arabian stallion that was extended using E-Z mixin® and supplemented with 0.12% and 0.24% EBN concentrations performed better and yielded superior results in sperm kinetic parameters and % viable compared to EquiPlus® at 24 and 48 h storage time.

This study investigates the impact of adding edible bird’s nest (EBN) to two different semen extenders, E-Z Mixin® and EquiPlus®, on the quality of chilled Arabian stallion semen. The findings suggest that EBN supplementation can enhance semen quality during chilling, particularly when used in the E-Z Mixin® extender at concentrations of 0.12% and 0.24%.

Methods and Materials

  • The study collected ten ejaculates from five stallions. These samples were diluted using either EquiPlus® or E-Z Mixin® extenders, which were supplemented with EBN at concentrations of 0%, 0.12%, 0.24%, or 0.24% with added seminal plasma (SP).
  • The extended semen samples were then stored at 5°C and assessed for quality after 0, 24, and 48 h.
  • Sperm quality was determined by evaluating sperm kinetic parameters using computer assisted sperm analysis (CASA), and viability was assessed using the Hoechst33342/PI stain.

Results

  • The research found that in both extenders, total motility (TM) and progressive motility (PM) were significantly higher in the 0.12% and 0.24% EBN concentration groups compared to the 0.24% + SP group at 24 and 48 h.
  • At a concentration of 0.12%, semen treated with the E-Z Mixin® extender had significantly higher TM and PM than semen treated with the EquiPlus® extender at both 24 and 48 h.
  • At 0.12% and 0.24% EBN concentrations, the E-Z Mixin® extended semen showed significantly higher average path velocity (VAP), straight-line velocity (VSL), and curvilinear velocity (VCL) compared to EquiPlus® treated semen at 24 and 48 h.
  • There were no significant differences in lateral head amplitude (ALH), linearity (LIN), straightness (STR), beat cross frequency (BCF), and viability between the two extender types at different EBN concentrations, regardless of storage time.

Conclusions

  • The addition of 0.12% and 0.24% EBN concentrations to the E-Z Mixin® extender (without SP) led to better CASA parameters, such as TM, PM, VAP, VSL, and VCL, at 24 and 48 h storage times.
  • The results suggest that EBN supplementation may offer a promising method for improving sperm quality during the chilling process, especially when used alongside E-Z Mixin® extenders at optimal concentrations.
