Abstract: An experiment was conducted to study the effect of supplementation of ewes with selenium in an inorganic and organic form on the level of IgG during infertility, pregnancy and lactation and in their offspring until two months of age. Control Group C (n = 5) was without Se supplementation. Experimental groups: E1 (n = 5) was supplemented with 180 μg Na2SeO3 per ewe/day, E2 (n = 5) received 180 μ Se per ewe/day organically bound in the biomass of an alga of the genus Chlorella. The average number of newborn lambs per lambing ewe was 1.0, 1.0 and 1.8 in Group C, E1 and E2, respectively. The supplementation did not influence either weight or growth of lambs. The content of IgG increased significantly in ewes in the last third of pregnancy regardless of Se supplementation while their postpartal decrease (P < 0.01) followed only in Group C. Lambs in Group C had a significantly lower level of IgG on Day 30 (P < 0.05) and 60 (P < 0.01) after birth especially in comparison with Group E2. The results document a lower level of immunity in the postpartal period of lambing ewes without Se supplementation and enhancement of postnatal proteosynthesis in the offspring of lambing ewes supplemented with the organic form of Se.
