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 micro m.s-1, the average progressive speed was 48.2 micro m.s-1 and the average straightness of the movement path was 58 per cent. The spermatozoa were classified and it was found that most frequently they moved at a path speed of 60-80 micro m.s-1 (28.2 per cent) and at a progressive speed of 20-40 micro m.s-1 (33.2 per cent). The path straightness classes above 40 per cent included evenly distributed numbers of spermatozoa; in classes with a less than 40 per cent straightness the numbers of spermatozoa were much smaller. These data are characteristic of fresh undiluted bull ejaculates, suitable for artificial insemination.
