| dc.description.abstract | Sperm morphometry has been extensively studied and proven to be important in assessing reproductive parameters. However, there are no studies yet on Philippine native pig epididymal sperm. This study established data about the morphometry of fresh and refrigerated eoididymal spermatozoa of mature native pig using computer assisted measurements. The recovery of epididymal sperm from the cauda of post-mortem testicles of six (6) Philippine native pigs was elucidated in this study. The effect of handling conditions in ice-cooled temperature of 4°C on epididymal sperm viability was also evaluated. Epididymal sperm from native pigs was collected using Minitube III and BST extender and was immediately recovered after death (≤ 1 hour) in Treatment 1 at 30-32°C handling temperature (4°C). The different morphometric parameters measured included sperm head length, width, area, perimeter and diameter, tail length, mid piece, flagellum and sperm total length. Results were analyzed using one-way ANOVA with post hoc test of LSD at 5% level of significance. The results of this study showed slightly lower values on morphometric measurements from refrigerated epididymal sperm compared to ejaculated sperm from hybrid pigs such as Polish Landrace. However, statistical analysis between fresh epid sperm and refrigerated epid sperm of Native pig, and ejaculated sperm from Polish Landrace showed little to no significant difference. This would mean that native pigs aged one-year old may be ready for collection of sperm for artificial insemination. | |
