...30 seconds and post-thaw sperm quality parameters were assessed. Sperm progressive motility, plasma membrane integrity, acrosomal integrity, viability and chromatin integrity was higher (P<0.05) in extender containing melatonin 0.1 mM and 0.5 mM compared to control. In conclusion, the addition of melatonin 0.1-0.5 mM to extender improved the post-thaw quality of buffalo bull semen.
