title: The ingestion of calcium in multiparous and virgin female rats.
abstract: The present experiments demonstrate that multiparous females ingest more calcium that virgin females. In two experiments, we demonstrated that multiparous females ingested more calcium than virgin females, and both ingested larger amounts than males. The biological basis for this enhanced avidity for calcium lie in the greater needs for calcium during reproduction.
