Summary

The available data on calcium, phosphorus and carbonate balance experiments with laying and non-laying birds have been collected and condensed. From this condensed data the following relationships have been derived:

(1) Calcium excretion is a function of calcium intake.

(2) Phosphorus excretion is a function of phosphorus intake.

(3) Carbonate excretion is a function of carbonate intake.

(4) Carbonate/calcium ratio of the excreta is a function of carbonate/calcium ratio of the intake.

(5) Calcium/phosphorus ratio of the excreta is a function of calcium/phosphorus ratio of the intake.
