Comparison between tris-citric acid yolk, yolk albumin citrate and skimmed milk extenders on sperm motility, livability and mass movement in frozen-thawed goat sperm.
This experiment was carried out with the aim to compare the effect of three extenders on frozen-thawed sperm characteristics in goat. Sperm of Katjang and their crossbreds; Jer-masia and Jermana were cryopreserved in three extenders namely tris-citric acid yolk (TCAYE), yolk albumin citrate (YACE) and skimmed milk (SME) and the frozen-thawed sperm parameter were examined. The finding of this study showed that the Jermasia and Jermana buck sperm cryopreserved in TCAYE provided the best results in terms of motility (52.64 ± 0.93% and 53.20 ± 1.13% ) and livability (56.47± 0.96% and 57.72 ± 1.11%), re-spectively. In the crossbreds, sperm motility and livability in TCAYE were found to be sig-nificantly higher compared to the sperm cryopreserved in YACE and SME. Therefore, TCAYE extender apparently is better than YACE followed by SME for the cryopreserva-tion of goat sperm.Author(s): Nor-Ashikin MNK andRBAbdullah
