Cryopreservation of Goat Sperms Collected From Different Regions of the Epididymis
Journal Title: UNKNOWN - Year 2013, Vol 2, Issue 7
Abstract
Cryopreservation of epididymal sperms in domestic and non-domestic animals has a number of important practical applications such as preservation of valuable genetic material from non-breedable animals. In the present study, the motility, morphology and viability of sperms obtained from head, body and tail of the epididymis were studied before and after freezing using eleven samples of goat epididymis collected from the Kandy abattoir soon after slaughter. To assess the changes of morphology and viability, smears stained with Eosin and Nigrosin were used. Statistically significant differences were observed in the motility and viability of sperms in the head, body and tail of the epididymis (P< 0.05) before and after freezing. Before freezing, the highest motility and viability were detected in sperms collected from the tail of the epididymis. The values observed were 75.45
