In this study, we examined the effect of a liposome-based extender (Optixcell) and a tris-citric egg-yolk extender (Triladyl) on the frozen-thawed spermatozoa characteristics and the calving rate. The percentages for the total motility of the frozen-thawed spermatozoa were similar in the Optixcell and Triladyl groups. However, among the motile spermatozoa with a straight line velocity (VSL) ≥ 25 μm/sec, the curvilinear velocity (VCL, μm/sec), VSL (μm/sec), average path velocity (VAP, μm/sec), amplitude of lateral head displacement (ALH, μm), beat cross frequency (BCF, Hz), and plasma membrane integrity of the frozen-thawed spermatozoa for the Optixcell group were significantly higher than those for the Triladyl group. Furthermore, the calving rate in the Optixcell group (79.0%) was higher than that of the Triladyl group (62.8%). However, the acrosomal membrane integrity of the frozen-thawed spermatozoa in the Optixcell and Triladyl groups was not significantly different. These results indicate that semen freezing with Optixcell improved the motility and plasma membrane integrity of frozen-thawed spermatozoa and the calving rate of Hanwoo cows (native Korean cattle). In conclusion, our results suggest that semen freezing with the liposome-based extender Optixcell is more efficient than with the tris-citric egg-yolk extender Triladyl for improved offspring production.
