A commercially available computer automated/assisted semen anlyzer (Hamilton Thorn Research Motility Analyzer, version 7) was used to evaluate percentage of motile spermatozoa, percentage of spermatozoa with progressive motility, path velocity and straightness of spermatozoa motion in five adult stallions. The aim was to determine the time-dependent (0, after 60 minutes) changes in the observed parameters. The percentage of motile spermatozoa was immediately after thawing (Time 0) 73.0% and after 60 minutes of incubation (Time 60) 73.8%. Spermatozoa with progressive motility decreased from 13.17% to 9.20% at Time 60. With decreasing percentage of spermatozoa with progressive motility their path velocity also decreased from 39.83 to 39.20 micro m per second. At Time 0 the straightness of spermatozoa motion was 73.83%, decreasing at Time 60 to 69.40%. In comparison of all parameters no significant differences were found
