The content of essential trace elements in tissues of piglet after actions of chromium chloride
The effect of chromium in dose of 250 and 400 µg / kg added to piglet diet on the content of essential trace elements in tissues: kidney, liver, spleen, lungs, brain, heart, skeletal muscle and skin was studied. It was established that chromium chloride in the amount of 250 µg Cr <sup>3+</sup>/ kg increased chromium content in the kidneys, liver and spleen, the content of iron increased in the liver and skin, but decreased in the spleen, the content of copper was higher in the liver, heart and skin but lower in kidney and increased content of manganese in the liver and heart, but decreased in the spleen, lungs and brain of 3 month piglet, compared to their level in the tissues of animals of the control group. By action of chromium chloride in the amount of 400 µg Cr <sup>3+</sup>/ kg of feed chromium content increased in kidney, liver, spleen, lungs, brain and skin, zinc — in the kidneys, liver, lungs, heart and skin, while the content of iron decreased in the liver, spleen, brain and muscles, copper — in the kidneys and liver, cobalt — in the kidneys and skin, manganese - in the lungs, brain and skin 5 monthly piglets. This indicates a dose dependent differences in age distribution of the studied trace elements in tissues of pigs for the actions of chromium.
