Effect of Pentoxifylline Concentration on Sperm Quality in Jeju Crossbred Horses

This study was conducted to determine the effect of pentoxifylline levels on sperm motility, survival rate, sperm membrane integrity of frozen semen and fresh-extended equine semen in Jeju cross-bred horses. As a result of sperm characteristic comparison depending on pentoxifylline levles at 30 minutes post-thaw, the progressive motilities were 53.25±2.87 (4mM pentoxifylline) and 50.28±2.14 (8mM pentoxifylline) and significantly higher compared to the control group(40.09±5.15) and other treatment group (16mM pentoxifylline, 41.27± 2.82). The progressive fast motility were 22.44±1.62 (4mM pentoxifylline,) and 22.74±3.07 (8mM pentoxifylline) and significantly higher compared to the control group (13.47±1.48) and other treatment group (16mM pentoxifylline, 14.66±3.68) (p
