THE LIPID PEROXIDATION AND ANTIOXIDANT DEFENSE SYSTEM OF THE ORGANISM OF COWS OF FOREIGN SELECTION DURING OF THE APPLICATION OF «CHITOSAN»

 In conditions of intensive livestock breeding topical issues of implementation of bioresource potential of cows and dairy productivity, mainly due to the import of cattle from abroad become actual. In the new ecological-economic conditions the

animals are exposed to various stress factors. One of the mechanisms of manifestation of stress reactions is the intensification of free-radical oxidation and depletion of the antioxidant system of the body’s defence in cows of foreign selection. The article presents the results of studies on the intensity of processes of lipid peroxidation and the status of antioxidant defense system of the organism of cows of foreign selection kept in the new ecological-economic conditions of the Southern Urals and correction of their antioxidant status with the natural biopolymer – «Chitosan». It is established lipotropic effect of stress and activation of lipid peroxidation is typical for the organisms of experienced cows characteristic, which is manifested by increased concentrations of total lipids, lipoproteins and the concentration of malondialdehyde, the decline of the level of ceruloplasmin and increased catalase activity, which requires the timely correction of identified changes. The results of these studies showed that cows fed in addition to the basic diet with «Chitosan» with a molecular mass of 120 kDa and a deacetylation 81 %, oppressed observed fat-mobilizing effect. During the application of «Chitosan» the reduction of concentration of malondialdehyde in 32.40 % (60 day) was accompanied by a significant increase in the content of ceruloplasmin on 22.38 %. «Chitosan», being able to capture the active forms of oxygen, acts as antioxidant, broad-spectrum, as evidenced by a significant decrease in catalase numbers up to 4.23 ± 0.04 μmol H2O2 at an initial level of 5.45 ± 0.07 μmol H2O2. «Chitosan» possesses antioxidant, hypolipidemic and anticholesterolemic properties, as evidenced by the established relationship between malonic dialdehyde and ceruloplasmin reduction of cholesterol level.
