Abstract
This investigation was undertaken to study, in a preliminary way, the effect of precipitating tricalcium phosphate in the presence of manganous salts. Certain facts in relation to manganese deficiency in the diet of fowls, giving rise to perosis, makes the problem of interest in view of the work carried out at the Agricultural Experiment Station at Colorado State College. (3). It has been known for a long time that a diet high in calcium produces perosis which can be corrected by peritoneal injection of manganese. (1). C. D. Caskey and L. C. Norris (2) have found that in the presence of large amounts of calcium and phosphate, perosis can be induced even when the manganese is considerably increased in the diet. It is known that tricalcium phosphate dissolves in the upper intestinal tract and precipitates again in the lower tract. (3). This suggests that in precipitating, the tricalcium phosphate removes the manganese either in a solid solution, in a chemical combination, or by some form of co-precipitation. (4). These possibilities can be investigated by phase rule studies. (5). Some work has been done by H.S. Wilgus and A.R. Patton (3) in vitro in the removal of manganese with tricalcium phosphate and ferric chloride solutions.
