Aims: The objective of the present study was to examine for the various biological activities for feed additives ofSaccharomyces 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 °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.
