Evidence was obtained in a previous study from the laboratory (Feher et al., 1970) for the excretion of 5.beta.-pregnan-3.alpha.,20.alpha.-diol and other epimeric pregnanediols in non-pregnant cow's urine. The present work supports additional gas-chromatographic evidence for the presence of 5.beta.-pregnan-3.alpha.,20.alpha.-diol, 5.alpha.-pregnan-3.alpha.,20.alpha.-diol and 5.beta.-pregnan-3.alpha.,20.beta.-diol in urine from non-pregnant cows. This gas-chromatographic study confirms the validity of the previous estimations.
