Abstract:
Objective: To investigate the effects of selenium enriched probiotics on antioxidative activities and immune functions in weanling piglets. Methods: Twenty-four healthy weanling piglets (Duroc?Landrace?Yorkshire ) were divided into 3 groups. One served as control group (C) and two were supplemented different selenium (Se) sources namely selenium enriched probiotics (T1) and Na selenite (T2) as test groups respectively . The experiment lasted for 60 days. The blood GSH-Px activity, blood Se concentration, serum superoxide dismutase (SOD) activity, serum malonaldehyde (MDA) level, serum antibody level of swine fever, and the tissue content of selenium were determined. Results: Blood GSH-Px , Se concentration and serum SOD activity of T1, T2 groups were higher than those of control group after 60 d Se supplementation, and serum MDA content was markedly lower than control group. At the same time, the serum antibody level of swine fever, the tissue content of selenium in T1, T2 group were much higher than control group, and T1 group was higher than T2 group. Conclusion: Organic Se supplementation could significantly enhance immune function and antioxidative activities of weanling piglets.
