Background: In the Philippines, there has been an increased interest in discovering the novel semen extenders for small ruminants and the duration of sustaining the motility of spermatozoa. The study aimed to determine and compare the suitable semen extender for Saanen buck spermatozoa at room temperature. The treatments were coconut milk-based extenders; skim milk-based extenders and non-addition of extender to semen.
Methods: Semen was collected from a healthy Saanen bucks with no andrological defects using the artificial vagina (AV) method to determine the motility and livability for 1, 2, 3, 4, and 5 hours at room temperature.
Results: Results revealed that percentage motility of coconut milk and skim milk-based extenders are comparable after an hour. Percentage motility of coconut milk-based extender is significantly higher than non-addition of extenders from 1 to 5 hours observation period. The sperm motility and livability decreased drastically after 3 hours in all treatments. Therefore, the coconut milk-based extender appears to be a better option compared to the skim milk-based extender, and non-addition of extender for semen of Saanen bucks. These extenders must be used within 2 to 3 hours because this is the period found to possess higher motility percentage.
Conclusion: Whether the differences found between the extenders will be reflected in the fertility results after artificial insemination (AI) is yet unknown and needs to be further studied.
