Correlations among Mg, Ca and P Contents of Digesta in the Gastro-Intestinal Tract of Rats

Abstract

Mg, Ca and P contents of feed, digesta in the gastro-intestinal tract (10 parts) and feces were determined in rats. Remarkable absorption of Ca in the upper small intestine and of Mg in the caecum were observed. Significant positive correlations were obtained between Mg vs. Ca, and also Mg vs. P contents from the feed to the digesta in the lower small intestine (p<0.001, respectively), and between Ca vs. P contents from the feed to the feces (P<0.001).
