Theаctivity of antioxidant enzymes system, the content of reducedglutathione, vitamin E and lipids in the blood of sows and pigletsif added to their diet at doses of chromium citrate 20 and 100 µg Cr(ІІІ)/kg feed were studied. Spectrophotometric and chromatographic methods of research shown that foractionschromiumcitrate, in the amount of 100mgCr(ІІІ)/kgfeedin sowson the 5-th dayafter farrowingincreasedsuperoxide dismutase, catalase, glutathioneperoxidase andglutathione reductaseactivity oferythrocytelysate, but declined content of triacylglycerols and cholesterol.Inpigs20days oldactionchromiumcitrate,in the amount of20 mgCr(ІІІ)/kg of feed, ledto an increase insuperoxide dismutaseand glutathione reductaseactivity oferythrocytelysateandcontentof vitaminE intheir bloodplasma, and in the amount of 100mgCr(ІІІ)/kg of feed — increasing the contentof reducedglutathione,glutathione peroxidaseand glutathione reductaseactivity oferythrocytelysate. These results suggesta positive effectinchromiumcitrateinvestigatedquantities inantioxidant systemin the body sows andnewbornpiglets.Reduction of triacylglycerols and cholesterol in the blood of sows second experimental group suggests corrective influence of Cr(ІІІ)on lipid metabolism in the first days after birth.
