The purpose of the present study was to assess the effect of a diet with 1% inclusion of sodium humate (HNa) on the concentrations of trace elements (copper, zinc, selenium, manganese, cobalt) in tissues of weaned piglets and on some biochemical indicators. The diet was fed during 21 days. In comparison with control animals, experimental piglets had significantly lower Mn levels in livers and kidneys, as well as Se levels in blood serum and muscles. On the contrary, they showed significantly higher daily body weight gains (0.303 vs. 0.258 kg), increased feed conversion rate (1.60 vs. 1.71 kg) and increased concentrations of blood serum glucose, triacylglycerols, Ca and Fe. The results of the present study indicate that sodium humate had some positive effects, but caused a decrease in concentration of physiologically important Mn and Se in the tissues of piglets.
