Abstract

The influence of age on endogenous urinary and faecal calcium excretion was studied. The animals, rats from Nestlé strain, weighing between 50 and 200 g ingest a calcium-free dieto
The endogenous faecal excretion in absolute values increases with age; however the values of endogenous faecal must be expressed referred to ingesta since endogenous faecal calcium comes from digestive secretions and from desquamation of intestinal mucous membrane, processes which depend on the volumen of ingesta. Wen they are adequately expressed (per 1 g of ingested dry matter) the values of endogenous faecal calcium become similar and there are no significative diJferences among them. With regard to urinary excretion of endogenous calcium it is in absolute values greater than faecal one, and it increases with age. Nevertheless when values are referred to corporal size (per 100 g of body weight) it is observed an increase in the young animals, that can be explained by the fact that calcium dynamics is increased by growth process.
