Taking into consideration the relevance and significant scientific and practical interest in the issue of probiotic preparations effect on various metabolism sites and productivity of farm animals, we have studied the probiotic feed additive “EnzActive mix” based on live Saccharomyces cerevisiae yeast on some metabolism sites, the content of lipid peroxidation products and the antioxidant defense activity in sows and piglets obtained from them. The actuality of such studies is explained by the significant interest in the use of probiotic preparations not only in human medicine, but also in the practice of animal husbandry. The aim of the work was to study the effect of the specified feed additive on some metabolism sites of the farrowing sows and the piglets obtained from them organism, on the lipid peroxidation products (LPP) content, as well as the activity of antioxidant enzymes, in particular, superoxide dismutase and glutathione peroxidase in their body. It was established that feed additive “EnzActive mix”, based on Saccharomyces cerevisiae yeasts, administration decreased the lipid peroxidation products (LPP) content (TBARS and lipids hydroperoxides) in sows and their progeny blood, in the result of the study. The reason for such LPP content decrease was the antioxidant defense enzyme — superoxide dismutase increase in the sows’ and their progeny’s RBC (red blood cells). However, it was admitted also feed additives’ positive effect on sows’ parameters of productivity.
