Description:

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 animal's vitamin D3 is essential for the normal development of skeleton and teeth. Vitamin E is as a fat-soluble intracellular antioxidant, involved in stabilising unsaturated fatty acids, thereby preventing toxic lipo-peroxides formation. Furthermore, vitamin E protects the oxygen-sensitive vitamin A from oxidative destruction in this preparation.


Indications:

Treatment and prevention of vitamin deficiencies in farm animals, such as growth disturbances, weakness of new-born animals, neonatal anemia, sight disturbances, intestinal troubles, convalescence, anorexia, not-infectious reproductive disturbances, rechitis, muscle weakness, muscular tremor and myocardial failure with difficulties in breathing; worm infections.
