Abstract
The study was aimed to evaluate the effect of three extenders viz. GEPS, BTS and Modena on quality of boar semen during preservation at 15°C and 5°C up to 96 hours. A total of 24 ejaculates were included for the study. The semen quality was significantly higher (P<0.05) in Modena followed by BTS and GEPS extended semen irrespective of preservation temperature and preservation period. Sperm motility, live sperm, live intact sperm and HOST-reacted sperm was significantly higher (P<0.05) at 15°C than 5°C. The sperm quality reduced gradually during different preservation periods. In conclusion, Modena extender was found to be superior to BTS and GEPS extenders for preservation of Hampshire boar semen.
