Results of the comparative study of the influence of natrium selenit and seleno-organic compound of selenopiran on the immune system of piglets were presented. Research results showed that intramuscular injection of selenopiran and natrium selenit to pregnant sows in the last two weeks of pregnancy and to weaning piglets increased the concentrations of immunoglobulin G (IgG) and immunoglobulin M (IgM) in colostrums, promoted the increasing of cellular immunity due to the protective effect on T-lymphocytes during the intensive free radical oxidation in organism of pregnant sows and suckling piglets. Selenopiran injection increased the concentrations of IgG on 52% and IgM – on 136%, natrium selenit administration increased the concentrations of IgG on 22% and IgM – on 100%. In the period of the early postnatal ontogenesis the piglets of the experimental group had higher concentrations of antibodies G-, M- and A-classes on 78, 20 and 34% accordingly, as well as the higher concentrations of selenium, IgA, IgG and IgM in boold serum
