Growth tests were made on rats, with the addition of sodium-phytate to the basal diet of low phosphorus, followed by metabolic tests of calcium and phosphorus, to obtain an information about the availability of phytin-phosphorus in the animal.
In the growth test, phytin-phosphorus was available evidently but was inferior to K2HPO4, as a phosphorus source.
In the metabolic test, the utilization (the absorption) of phytin-phosphorus was lower than that of K2HPO4. Although the absorbed phytin-phosphorus was apparently accumulated in the body, the retention of calcium was diminished by the phytin-P intake.
