Observations on the Mineral Metabolism of Pullets: IX. The Effects of Estrogen and Androgen Administered Separately on the Retention of Calcium by the Sexually Immature Pullet1

Robert Haddon Common, W. A. Maw, J. R. Jowsey

Abstract

An experiment is described in which sexually immature pullets were treated with either (a) no hormones, (b) androgen, (c) estrogen or (d) estrogen plus androgen, given concurrently. Estrogen plus androgen increased average daily calcium retention to a level significantly higher than did the other treatments, confirming previous work. Estrogen or androgen increased average daily calcium retention slightly but significantly. There was a significant interaction of estrogen and androgen in regard to the large increase of retention evoked by estrogen plus androgen.
