The changes of vitamin E and selenium, lactatedehydrogenase, creatine, peroxide resistance to erythrocyte lipides, glutamatdehydrogenase, aspartate aminotransaminase, alanine aminotransaminase, potassium and sodium were investigated in growing piglets with vitamin E and selenium deficiency, depending on lipid quality and vitamin E levels in the feed. It was established that feed lipids have a high oxidation rate (within 20.2-88 meq/kg), i.e. 6.5 to 29.5 times above the average adopted value and insignificant vitamin E concentration (0.3-65.5 mg%) or none. The dynamics of biochemical processes in influenced by lipid quality and the concentration of vitamin E and selenium in feed. Thus the activity of aminotransaminases ASAT and ALAT, hydrogenases LDH and GDH, creatinine (C) and peroxide resistance of erythrocyte lipids (PREL) increases in ill piglets, while the levels of extracellular electrolyte Na and intracellular electrolote K remain stable. The biochemical changes observed in piglets with vitamiv E and selenium deficiency are indicative of the participation of oxidation stress in disease pathology.
