Relationship of conventional and fluorescent microscopic technique to assess in vitro semen quality status of Murrah buffalo males

In vitro fertility assessment using fluorescent technique is a better predictor of fertility status of bulls as compared to traditional semen quality assessment techniques, therefore, the study was planned to assess in vitro fertility status of bulls based on conventional and fluorescent techniques. Seventy-three ejaculates were collected from 12 Murrah buffalo bulls maintained at Artificial Breeding Research Centre, NDRI, Karnal, India for the experiment and subjected to statistical analysis using SYSTAT. The mean values of ejaculate volume (ml), mass activity, individual motility (%), sperm concentration (millions/ml), live sperm (%), total abnormalities (%), HOST (%) and acrosomal integrity (%) were 2.70 ± 0.28, 2.8 ± 0.14, 63.8 ± 2.16, 1749.7 ± 122.24, 77.3 ± 2.48, 6.2 ± 0.51, 75.1 ± 1.81 and 84.5 ± 2.26, respectively. The repeatability estimates were significant (P
