The peculiarities of antioxidant defense and lipid metabolism in the organism of sows and pigs under chromium citrate action
The аctivity of antioxidant enzymes system, the content of reduced glutathione, vitamin E and lipids in the blood of sows and piglets if 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 for actions chromium citrate, in the amount of 100 mg Cr (ІІІ)/kg feed in sows on the 5-th day after farrowing increased superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase activity of erythrocyte lysate, but declined content of triacylglycerols and cholesterol. In pigs 20 days old action chromium citrate, in the amount of 20 mg Cr (ІІІ)/kg of feed, led to an increase in superoxide dismutase and glutathione reductase activity of erythrocyte lysate and content of vitamin E in their blood plasma, and in the amount of 100 mg Cr (ІІІ)/kg of feed — increasing the content of reduced glutathione, glutathione peroxidase and glutathione reductase activity of erythrocyte lysate. These results suggest a positive effect in chromium citrate investigated quantities in antioxidant system in the body sows and newborn piglets. 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.
