Popis: Fresh and frozen semen quality of Murrah and Nili-Ravi bulls in comparison with indigenous buffalo bulls was evaluated by Computer Assisted Sperm Analyzer (CASA). Semen was collected regularly once a week semen collection schedule from six (two/group) buffalo bulls. Fresh semen was evaluated for sperm concentration, motility, sperm kinematics, morphology and dose/ejaculate. Semen was diluted in a commercial extender (AndroMed), equilibrated, cryopreserved and finally evaluated for post-thaw sperm quality. On-station Artificial Insemination (AI) was carried out in naturally estrus indigenous buffalo cows at their second or third parity. Semen volume and concentration did not vary significantly (p>0.05). In fresh semen, total, static and slow motility differed significantly among the groups (p
