Semen of 10 Tsigai,3 Prolific Merino and 7 Barbados Blackbelly rams was taken in January, out of the season. Split samples of the diluted semen samples were kept at 23, v.s. 8 o C and their motilitywas evaluated daily for 3 days by subjective microscopic investigation. The ratio of motile spermatozoa was strongly decreased during the first day, later the motility rate was sinking more slowly. It could be stated by multivariance analysis that the motility value of diluted semen of Prolific Merino rams was higher and showed a slower reduction as compared to the other two breeds. The decrease of the motility rates was slower at 8 o C than at 23 o C.
