Abstract: This study evaluated the variation in semen characteristics between two individual Murrah buffalo bulls. Two hundred and ninety semen samples were involved in this study. The results showed that most of the semen had a milky white color with moderate consistency. The Bull B1 tended to have higher proportion of creamy color and moderate consistency than the Bull B2. The ejaculatory volume is varied (P<0.01) between Bull B1 and Bull B2. However, semen pH and sperm concentration of Bull B1 and B2 were equal (P>0.05). The individual bull had a highly significant effect (P<0.01) on sperm motility of fresh semen. The individual variation (P<0.05) also found on sperm motility of before freezing. Whereas, sperm motility of post-thawing semen and recovery rate value were not significantly influenced (P>0.05). Moreover, it was found that the frozen semen production differed (P<0.01) between two individual bulls, with bull B1 had higher production than the bull B2. This study clearly demonstrates that the frozen semen production of Murrah buffalo is highly dependent on the individual bull. However, the variation in frozen semen production between two bulls studied here is still qualified to be used for artificial insemination.
