title: [Analysis of the motility of bull sperm in fresh ejaculates using computer technology].
abstract: The activity of spermatozoa was measured in the fresh non-diluted ejaculates of 10 breeding bulls, using the HTM motility analyzer version 7. The average path speed was 83.6 microns.s-1, the average progressive speed was 48.2 microns.s-1 and the average straightness of the movement path was 58%. The spermatozoa were classified and it was found that most frequently they moved at a path speed of 60-80 microns.s-1 (28.2%) and at a progressive speed of 20-40 microns.s-1 (33.2%). The path straightness classes above 40% included evenly distributed numbers of spermatozoa; in classes with a less than 40% straightness the numbers of spermatozoa were much smaller. These data are characteristic of fresh undiluted bull ejaculates, suitable for artificial insemination.
