Abstract
AIMS: The objective of the present study was to examine for the various biological activities for feed additives of Saccharomyces cerevisiae and fermented rice bran. METHODS: The feed additives (100 g of each: YE, brewery yeast; PM, mixture of YE and SF; SF, fermented rice bran) were decocted with 2 l water at 100 degrees C to a half volume. RESULTS: The hot-water extract of PM was found to increase the stimulation of the macrophage activation (2.0-fold) and the intestinal immune modulating activity (1.8-fold), compared with those of control. When the hot-water extracts of PM, SF and YE were fed to the rats for 8 d (1 g kg-1 d-1), PM and SF showed the more effective anti-stress effect on spleen, thyroid and thymus gland. SIGNIFICANCE AND IMPACT OF THE STUDY: The hot-water extract of PM can have a significant impact on strengthening the living body's immune system and proliferating anti-stress activities with relation to enhance immunity.
