The effects of Bacillus subtilis C-3102 (C-3102) on fecal microflora of sows and gilts were studied. Sows and gilts were fed an experimental diet containing C-3102 (1 x 10(7) cfu/g) for 3 weeks. After the 3 weeks test period, the number of Bifidobacterium significantly (P0.05) increased, whereas Streptococcus significantly (P0.01) decreased and the detected rate of Clostridium perfringens decreased in snow feces. In gilts, the number of Bifidobacterium (P0.01) and Lactobacillus (P0.01) significantly increased, whereas the number of Streptococcus (P0.01) and the detected rate of Clostridium perfringens (P0.05) significantly decreased. The change in fecal microflora was more evident in gilts than sows. The diarrheal rate of piglets until 10 days-old was significantly reduced and the mortality rate until 25 days-old tended to be lower, when their sows were fed with a diet containing C-3102 for 6 months. In another farm, sows wee fed an experiment diet containing C-3102 (1 x 10(7) cfu/g) for 3 weeks. After the 3 weeks test period, the number of Lactobacillus significantly (P0.05) increased, whereas Streptococcus (P0.05), Enterobacteriaceae (P0.05), C. perfringens (P0.05) and Bacteroidaceae (P0.05) significantly decreased in sows feces. Furthermore, the water content in the feces significantly (P0.05) increased. A significant positive correlation between the levels of Bifidobacterium (P0.01), Lactobacillus (P0.05) and fecal water content was observed, and a significant negative correlation between Enterobacteriaceae (P0.05), C. perfringens (P0.05) and fecal water content existed. These results suggested that ingestion of C-3102 can significantly improve the fecal condition of sows and gilts. Furthermore, intake of C-3102 by the sows can decrease the occurrence of diarrhea among newborn piglets
