It was found that in rams with established sexual reflexes the maximum values of testosterone and of the studied indices of the ejaculate were observed at 8 h in the morning and between 11.30 and 13.30 h independently on the age and the breed. This time may be considered as optimal for obtaining of semen material from rams.
