The results obtained from the experiment indicated no significant differences in semen volume (ml) motility (%) and live count of spermatozoa at different ejaculation frequencies; but the trend showed that mean semen volume was highest at the ejaculation frequency of twice in a week. Motility was highest at the ejaculation freqency of once in a week. Significant differences (p 0.05) in abnormality (%) and concentration (Millions/ml) of spermatozoa at different ejaculation frequencies were observed. But Duncan's New Multiple Range Test showed no significant differences among the concentration of spermatozoa at the ejaculation frequency of once, twice and thrice in a week. Similarly, Duncan's test for abnormality showed insignificant differences between the ejaculation frequency of twice and thrice in a week. It may therefore, be inferred from the experiment that 2 to 3 times collection frequency can be followed in the schedule of semen collection from native ram of Bangladesh without deteriorating the quality of semen.
