Abstract:

75 male Kuming mice were randomly divided into control, sodium selenite, organic-selenium (Se) with inactivated probiotics, Se-enriched probiotics or probiotics groups (n=15) in the experiment, and all the mice were fed for 30 days. The growth performance, Se concentration in blood and skeletal muscle, anti-oxidation status and resident intestinal flora of each treatment group were studied to compare their differences. The results indicated that the body weights of mice fed Se-enriched probiotics diet are higher than those of others after fed for 30 days. Anti-oxidation status and Se concentration in blood increase when Se is supplemented; however Se content in skeletal muscle of the mice fed inorganic or organic Se is lower than that of mice fed selenium-enriched probiotics. The composition of resident bacterial flora in gut is enhanced when mice are fed with probiotics. In conclusion, the measured indexes of mice fed selenium-enriched probiotics are markedly better than those of other groups.
