Intestinal calcium-binding protein in animals fed normal and rachitogenic diets: II. Pig studies

Experiments were carried out in pigs to investigate the relationship between concentration of intestinal calcium-binding protein (CaBP) and the presence of rickets. Pigs made rachitic by a diet deficient in calcium and in vitamin D had concentrations of intestinal CaBP no less than values obtained on control pigs. These experiments, together with earlier work on rats (Can. J. Physiol. Pharmacol. 1975. 53, 137--143), demonstrate a poor inverse correlation between levels of intestinal CaBP and rickets.
