The present study was designed to compare the efficacy of different liquid semen extenders for preservation of boar semen at 15°C. Twenty ejaculates, four from each of five Hampshire boars were used to study the efficacy of BTS, GEPS, FEY and LSEEY extenders for preservation of boar semen at 15°C up to 72 h. The mean sperm motility, live sperm and live spermatozoa with intact acrosome were found to be significantly (P < 0.05) higher in GEPS as compared to other extenders. The sperm motility, live sperm and live spermatozoa with intact acrosome differed significantly (P < 0.01) between extenders, preservation periods and interaction of extenders and preservation periods. GEPS was found to be the best extender for preservation followed by BTS, LSEEY and FEY.
