Vitamin D3 can maintain normal metabolism of calcium and phosphorus, and promote the body's absorption of calcium and phosphorus. The utilization of vitamin D2 and vitamin D3 in pigs is equivalent, but the utilization of vitamin D2 in poultry is only 1/3 to 1/40 of D3. In the absence of D3, eggshells became thin, the egg production rate decreased, and rickets occurred.
Vitamin D3 is a fat-soluble vitamin, is used as a precursor for calcium, phosphorus metabolic hormones, it has close relationship with sunshine, so also called the "sunshine vitamin".
Vitamin D3 is fat-soluble, insoluble in water, can dissolve in fat or fat solvents, high temperature and oxidation in neutral and alkaline solution.
