Abstract: The present study determined the effect of different types of sugars (lactose, fructose, glucose and sorbitol) used in egg yolkbased extender on the post-thawed boar semen quality. Twenty-two ejaculates from 6 fertility-proven Yorkshire boars were cryopreserved by liquid nitrogen vapor method. Sperm motility, viability, acrosome integrity and intact functional plasma membrane were determined at 0, 2 and 4 hr after thawing. It was found that the lactose-based extender resulted in a higher percentage of post-thawed sperm motility, viability, intact acrosome and functional plasma membrane than sorbitol-based extender (P < 0.05) and fructose-based extender yielded a higher post-thawed sperm motility and viability than sorbitol-based extender (P < 0.05). It could be concluded that sorbitol was not an effective sugar for the cryopreservation in boar semen. © 2012 The Japanese Society of Veterinary Science.
