Abstract:

In order to investigate the effect of selenium-enriched bovine colostrumson on immune function of immunodepressed mice induced by cyclophosphamide, selenium-enriched Rhodopseudomonas palustris G3 (hereinafter called selenium-enriched G3) was mixed with bovine colostrumson to prepare selenium-enriched bovine colostrumson. The immunodepressed mice were treated with selenium-enriched G3, bovine colostrumson and selenium-enriched bovine colostrumson, respectively. The administration was carried out once a day for 47 successive days after 3 days of adaptive feeding, and organ index, white blood cell number, T-cell population, the contents of SOD and GSH-Px in blood, and feed/gain ratio of mice were determined at the end of the administration. Results indicated that selenium-enriched G3, bovine colostrumson and selenium-enriched bovine colostrumson could increase the utilization efficiency of diet, enhance the activities of SOD and GSH-Px in blood, and improve mouse immune function. Compared with the control group, the selenium-enriched bovine colostrumson exhibited best improved immune at the high dosage.

Key words: selenium, bovine colostrumson, Rhodopseudomonas palustris, cyclophosphamide, immunization
