Abstract
Cryopreservation of Malabari buck semen provides valuable genetic preservation, but its effectiveness is hindered by cryodamage, with low-freezability (LF) bucks being particularly susceptible. This study evaluated fresh and post-thaw sperm quality in high-freezability (HF) and LF bucks. HF bucks demonstrated significantly higher post-thaw motility (47.50±1.53% vs. 15.75±1.16%), viability (78.45±0.41% vs. 73.35±0.97%), acrosomal integrity (62.65±0.91% vs. 44.60±1.67%), and hypo-osmotic swelling (HOS) response (62.65±0.92% vs. 38.65±1.91%) compared to LF bucks (p
