Abstract
The study aimed to determine the efficacy of different semen extenders and in vitro storage periods on the Windsnyer boar sperm quality equilibrated at 18°C. Ejaculates (n=18) from three Windsnyer boars of known fertility were evaluated for macroscopic traits, pooled, and then allocated for extension in Beltsville Thawing Solution (BTS) and Kobidil+ extender. Diluted semen was stored at 18°C and evaluated at 0, 4, 8, 12, 24, and 48 hours post collection for sperm microscopic traits. Semen diluted with BTS extender maintained the highest live normal sperm percentage at 4 (63.0±10), 8 (49.6±8.7), 12 (38.0±12.6), 24 (22.6±10.7) and 48 (12.0±10.7) hours, when stored at 18°C (P<0.05). The BTS extender maintained the sperm total motility greater than 40% up to 24 hours at 18°C as compared to the other semen Kobidil+ extender treatments (P<0.05). Average <5% of sperm abnormalities were recorded over 48 hours of in vitro boars semen storage irrespective of the semen extenders. Windsnyer boars sperm quality was maintained over 48 hours when the semen was diluted with BTS and stored at 18°C.
