Vitamin A is involved in the process of formation and preservation of function of epithelial tissues and mucous
membranes, is important for fertility, and is essential for vision. Vitamin D3 regulates and corrects calcium and
phosphate metabolism in blood and plays an important role in the uptake of calcium and phosphate from
the intestines. Especially in young, growing animals vitamin, D3 is essential for the normal development of the
