Abstract: By means of new organic selenium plant biotechnology ,Se-enriched tea was developed by fertilization in soil or foliar spraying of selenium in soil-plant system.An animal test was carried out The rats were fed both a selenium-deficietnt basal diet ,supplemented with water,sodium selenite,extraction of low Se tea and a diet with Se-enriched tea respectively.The results showed that selenium contents in blood and liver were signifiacntly increased in rats fed with extraction of Se-enriched tea and sodium selenite compared with that of low Se tea extraction and water.The higher efficacy was produced by selenium in Se-enriched tea.The significant difference was obtained in rat phagocytic cell percentage and phagocytic index in rats fed with Se-enriched tea and sodium selenilte in comparison with that fed with lowse water.Se-enriched tea could improve rat immune efficacy and be used as a good source for raising animals and human selenium intake.
