Biochemical status of cows, both local and imported in terms of the Voronezh region

Monitored and represented the fluctuation range of blood biochemical parameters in dairy cows domestic and imported. Reviewed nineteen farms in the Voronezh region. Blood tests were performed in the chemical-Toxicological Department of the Voronezh regional veterinary laboratory. The equipment is certified, the procedures of common tests. Cows domestic breeding to a greater extent recorded disorder of carbohydrate metabolism. Imported animals often manifests itself a violation of protein and mineral metabolism and the severity of cytolysis. Elevation of transaminases imported cows is more common than domestic animals with a wider range of deviations of indicators of activity of AsAT and AlAt from physiological limits. The detected changes in biochemical blood indices of animals testify to violation of carbohydrate, protein, vitamin and mineral metabolism, the severity of cytolytic and hepatorenal syndrome and the development of steatosis, osteodystrophy, vitamin A deficiency and microelementoses.
