[Lipids and their antioxidant activity in tissues of ruminant animals]

The work deals with the estimation of lipids in the bovine tissues (liver, intestine, skin) of the animals bred for the industrial purposes. The tests displayed, that depending on ration, breeding conditions and providing the animals organism with vitamins, the lipids levels in the liver, intestine and skin changes. As a result of the experiments the conclusion was made that deficiency of fatty-soluble vitamins A, D, E in the animals fodder provided for the disturbance of lipid metabolism in their organism and for the development of a pathologic process: a light form of alimentary parathyroid-osteodistrophia. This state was eliminated by means of additive intramuscular injection of the above listed vitamins. Estimation of the test animals tissue lipids properties revealed, that the provision of the organism with the vitamins led to the increase of the level of some natural antioxidants. Normal development of animals is provided when they are fed by natural products.
