摘要:
This study investigated the effect of season, age and period on semen traits in buffalo bulls. Data collected during the year 2010-2021 for seven semen traits viz. ejaculate volume (VOL), sperm concentration (SPC), mass activity (MA), initial motility (BFM), post-thaw motility (PTM), number of sperms per ejaculate (NSP) and number of motile sperm (NMSP) from Murrah buffalo bulls (n = 45; aged: 24-75 months). A general mixed model was applied to obtain the R2 value which was the proportion of variation in semen variable. With study period, the highest SPC was obtained during 2012; with the season, the highest VOL (ml) in hot humid and the highest SPC during the hot-dry season and with age, higher VOL, SPC, NSP and NMSP was obtained in older bulls. This study showed that factors i.e. period, season and age had a significant effect on semen traits viz. VOL, MA, SPC, BFM, PTM, NSP and NMSP in buffalo bulls.
