[Evaluation of the motility of boar sperm using computer technics]

The motility of the spermatozoa of a normally fertile boar was measured by means of the Cellsoft Computer Automated Semen Analyzer. The following values were obtained for the chosen parameters: average speed of motion (V) 20.842 microns per second, average linearity (L) 4.960, average amplitude of lateral deflection of the head (LPH) 0.90 microns, frequency of average path intersection (FPD) 11.44 s. There were 46 spermatozoa with circular motion (27.71% of motile sperms). The majority of the spermatozoa (52%) moved at the rate of 10 to 20 microns.s-1, and linearity was most frequently in classes 3 to 4 (16%). The Semen Analyzer has brought progress in the evaluation of sperm motility; hence, the apparatus should be recommended for use in State Animal Enterprises and their A.I. stations.
