“…Computer‐Assisted Sperm Analysis (CASA) provides comprehensive and precise information on different sperm motion attributes (Kathiravan, Kalatharan, John Edwin, & Veerapandian, ). Moreover, postthaw motion kinematics has positive correlation with in vitro & in vivo fertility in bovine (Ahmed, Andrabi, & Jahan, ; Kathiravan et al., ). In this study, significant improvement was recorded in postthaw sperm CASA motility, morphology, progressive motility, motion kinematics (path velocity, straight line velocity, curvilinear velocity, beat cross‐frequency, straightness, length of average path, length of straight line path and length of curvilinear path) of spermatozoa cryopreserved in OptiXcell ® compared to Tris egg yolk‐based and Triladyl ® extenders.…”

Our objectives were to ascertain the comparison of Tris egg yolk-based, Triladyl and Optixell extender on postthaw quality, CASA parameters and in vivo fertility of Nili Ravi buffalo (Bubalus bubalis) bull spermatozoa. Semen samples (n = 35) from five bulls were diluted in Tris egg yolk-based, Triladyl , Optixell extender and frozen in 0.50 ml French straws. Postthaw sperm CASA motility (%) was higher (p < 0.05) in Optixell extender as compared to Triladyl and Tris egg yolk-based extender. Although sperm progressive motility (%), morphology (%), average path velocity (μm/s), straight line velocity (μm/s), curvilinear velocity (μm/s), amplitude of lateral head displacement (μm), beat cross-frequency (Hz), straightness (%), length of curvilinear path (μm), length of average path (μm), intact plasma and acrosome membrane (%), and DNA integrity (%) were higher (p < 0.05) in spermatozoa cryopreserved in Optixell extender as compared to Tris egg yolk-based and Triladyl extender. The fertility rates (68.18%, 45.45%, 55.4%) were higher (p < 0.05) in buffaloes inseminated with semen doses frozen in Optixell extender than the Tris egg yolk-based and Triladyl extender respectively. It is concluded that Optixell extender improves postthaw semen quality and fertility in Nili Ravi buffaloes.

“…() found high and significant correlations between the subpopulation of the most rapid and progressively motile sperm in frozen‐thawed semen from Holstein bulls and the results of sperm‐ZP binding assays (ZBA) ( r = 0.79) and IVF tests ( r = 0.60). And Ahmed, Andrabi, and Jahan () found a significant positive correlation ( r = 0.73) between the subpopulation of most rapid and progressive sperm and field fertility of buffalo bulls. Similar studies have not been done in dogs, in part because of the difficulty for in vitro maturation of canine oocytes, what precludes performing IVF tests, but also because only a small number of bitches can be inseminated with a single ejaculate, which reduces the sensitivity of in vivo fertility trials.…”

Contents Studies performed on ejaculates from several species have identified discrete subpopulations of motile sperm. In dogs, motile sperm subpopulations have also been described in fresh and frozen‐thawed semen. The subpopulation of the most rapid and progressively motile sperm has been suggested to be the most likely source of fertilizing spermatozoa. However, the significance of subpopulation differences among dogs and ejaculates relative to fertility is not known. The aim of this study was to investigate the relationship between the relative proportion of motile sperm subpopulations in frozen‐thawed dog semen samples and their ability to bind to the zona pellucida of canine oocytes. Multiple linear regression analysis indicated that the subpopulation of the most rapid and progressively motile sperm was significantly and positively correlated with zona pellucida‐binding assays (ZBA) outcomes: each 10% increase in this subpopulation was associated with an increase of 1.5 sperm bound per oocyte. Subpopulations of hyperactivated‐like or locally motile sperm were negatively correlated with the ZBA results. It was concluded that subpopulation differences among frozen‐thawed dog semen samples determined differences in the number of sperm bound to the ZP of canine oocytes.

“…For that reason, the variation of frozen semen production between two bulls could not inhibit the use of both bulls for artificial insemination. Additionally, both of Bull B1 and B2 had a similar result on post-thawing sperm motility, which was previously categorized as the best single predictor for field fertility of buffalo [14,15].…”

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) 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. . 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
