[The nutritive utilization of phosphorus in dietary calcium deprivation (author's transl)].
The influence of alimentary calcium deprivation on the nutritional utilization of phosphorus and its corporal retention, after ingestion of diethylstilbesterol has been studied in quail. When female quail are given a highly calcium-deficient diet, egg-laying stops and there follows a substantial decrease in phosphorus utilization and retention, as well as a clear drop in bone mineralization, with calcium and phosphorus content losses in the femur. In males, deprivation of alimentary calcium shows tangible effects on phosphorus retention only when this situation concurs with prior ingestion of diethylstilbestrol.
