Summary. Purpose of the intensive animal breeding is to increase the production of beef and dairy cattle. Accurate determination of nutritional and health status of animals is invaluable in modern animal agriculture. The examination of biological fluids using modern laboratory techniques has already been commonly used in diagnosis of metabolic disorders in dairy and beef cows. Till now, no detailed findings have been published concerning biochemical parameters in healthy beef cows compared with those suffering from metabolic disorders. Blood metabolite levels indicate the extent of metabolism of energy, proteins and other nutrients in animals. They are necessary for the development of therapeutic measures metabolic disorders. Мetabolic profile of dairy and beef cows is different in some aspects. Significantly different protein, fat and mineral metabolism. High risk of violating protein metabolism in beef cows. Hereford cows are not at risk of developing fatty liver cytolytic and hepatodepressive syndrome of liver. Blood serum calcium concentration in Hereford cattle was 13.0% and serum zinc concentration content of below 33.0%. Blood serum phosphorus concentration in group of beef cattle was significantly higher, compared to group of dairy cattle. New knowledge in the field of animal nutrition and the rapid development of clinical biochemistry create favorable conditions for the investigation and influencing the growth of beef cattle capacity, for its active production and health control.

Keywords: metabolic profile, metabolism, clinical biochemistry, Hereford breed, Ural breed cattle, enzymes, microelements, substrates.
