The vegetable fats are composed of unsaturated fatty acids. Some of them are not synthesized in the body and reduce the level of cholesterol in the blood and their lack detains the growth and development of the organism.

Vitamins are organic compounds with high biological activity, necessary for normal growth and development. They participate in the formation of many systems, which are regulators of the biochemical processes in the body. Animals often experience a lack or deficiency of vitamins, which are not synthesized in the body and not stored well in the source of food.

Vitamins are divided into lip soluble (A,O,K,E), water-soluble (В1,В12,В6,В2,РР, folic, ascorbic acid). Most are found in the foods, but due to negligent nutrition, most of them are destroyed. Shortages in food results in different diseases - hypovitaminosis, lowered immunity and reduced quality of life. Hamsters are noted in various disorders: indigestion, convulsive movements and paralysis, blindness, distortion. In winter feeding it often happens to have a lack of vitamins A, D, E, and some of group B.

VITAMIN A

It is necessary for the normal growth of young animals and the metabolism, its lack can cause a development of "night-blindness, loss of weight, the animals do not proliferate. Excess of vitamin A deposited on the liver, forms a reserve shortage and causes many diseases. This vitamin is not contained in the plant food, it is in the form of carotene which body turns into vitamin A. Young green plants, the leaves of clover, alfalfa, milk, egg yolk and carrots are rich in carotene.

VITAMIN D

Regulates the phosphor-calcium exchange and contributes to normal formation of bone tissue.
In case of shortage, the mineral exchange disorders and could lead to rickets in young animals and adults are with reduced fertility. At high doses of this vitamin or its analogue influences on the hamster as a strong poison leads to liver disease.

VITAMIN E

Facilitates the absorption of fat soluble vitamins, ensures the normal function of reproductive organs, nerves and muscle tissues, normalizes the growth and structure of cells. Its shortage reduces the fertility in females or they don't have descendants at all, males have degeneration of the testes and sterility. It is contained in a sprouting bud wheat maize, peas, eggs and milk.
