Differences between manual and machine motility analysis was determined for total motility (MOT) of bull semen samples (N=117) three ways: manual analysis on a microscope and on computer-assisted semen analysis (CASA) systems: Hamilton-Thorne IVOS and Minitube SpermVision (SV). CASA analysis includes progressive motility (PRO) and related kinematic parameters. Analysis indicated differences between MOT: 83.06 (IVOS), 75.84 (manual), 65.48 (SV), and PRO: 44.25 (IVOS) and 60.07(SV). Relationships existed between manual MOT and both IVOS MOT (r=0.32) and SV MOT (r=0.59). The relationships between IVOS and SV MOT and PRO was notable (r=0.70 for both MOT and PRO).
