This study investigated the influence of dried okara-tempeh, the insoluble portion of soybeans fermented with ragi-tempeh, on fecal microbiota and metabolites in dogs. Three dried okara-tempehs (individual weight: approximately 5 g) were given daily to each of 6 beagle dogs for a period of 2 weeks. The concentrations of fecal short-chain fatty acids, pH, and microbiota were determined. During the intake of the dried okara-tempeh, the level of Bifidobacterium expressed as log(10) number (CFU)/g wet feces was increased significantly (p<0.05) from 6.4 +/- 0.9 (mean +/- SD) to 8.8 +/- 0.8, and the level of Bacillus was also increased significantly (p < 0.05) from 4.1 +/- 1.8 to 7.3 +/- 0.6. Moreover, fecal concentrations of total short-chain fatty acids, acetic acid and propionic acid also increased significantly (p < 0.05) from 146.7 +/- 15.9 mu mol/g wet feces to 198.8 +/- 24.6 mu mol/g wet feces, from 90.3 +/- 8.6 mu mol/g wet feces to 116.3 +/- 17.91 mu mol/g wet feces, and from 39.3 +/- 3.7 mu mol/g wet feces to 60.0 +/- 9.1 mu mol/g wet feces respectively on day 7 of dried okara-tempeh intake compared to pre-intake. Fecal pH decreased significantly (p < 0.05) from 6.2 +/- 0.3 to 5.6 +/- 0.2 during intake. The findings obtained by this study demonstrate that the intake of dried okara-tempeh was effective for improving the fecal environment in dogs and that okara, which is currently discarded, can be effectively utilized in dog feed.
