This study was conducted to investigate the effects of brown seaweed waste (BSW) fermented with DS-01 microbe on in vitro rumen microbial fermentation. In in vitro trial, three different diets supplemented with 2%, 4%, 6% BSW fermented with DS-01 either for one month or two months was tested at 3 h, 6 h, 9 h, 12 h, and 24 h incubation. The chemical composition (CP, EE, CF, and ash) between brown seaweed waste (BSW) and fermented BSW (FBSW) were not different. The contamination of pathogenic microbes was not detected in FBSW. The pH value tended to be higher with 6% level of supplementation of FBSW for one month than other treatments. The pH at 24 h was significantly higher in FBSW than that of treatments without FBSW (p<0.05). In FBSW for two months, the pH value in 6% FBSW at 3 h in vitro fermentation tended to be higher than 2% or 4% FBSW treatments (p=0.0540), but there were no differences in other fermentation times. Although the concentration of NH3-N of BSW fermented for one month was higher than control at 3 h (p<0.05), the volatile fatty acid values were significantly increased in 4 and 6% FBSW fermented for one month at 6 h incubation (p<0.05). In BSW fermented for two months, the volatile fatty acid values were significantly decreased in 6% treatment at 9 h (p<0.05). As a result of in vitro trial, it was recommended that the 2~4% supplementation level of brown seaweed waste fermented with DS-01 microbe for two months could be utilized for in vivo trial in ruminants.
