| Research Abstract |
In an attempt to improving boar sperm quality which decreases in summer and stable provision with semen leading to stable production of pork during the year, this study investigated a new diluent for boar semen storage, a new method to evaluate frozen-thawed bull sperm quality and development of a method to improve fertilizing ability of frozen-thawed bull spermatozoa. Bull spermatozoa were used as a reference to boar spermatozoa. Modified diluents for boar semen improved conception rates. In bulls, new method for sperm evaluation was found out and modification of diluent for freezing bull semen enabled improvement of sperm fertilizing ability.
