The effect of disodium fumarate (DF) on the ruminal fermentation profiles, the accumulation of lipopolysaccharide (LPS) and bioamines, and the composition of the ruminal bacterial community was investigated by in vitro rumen fermentation. The addition of DF increased the total gas production; the concentrations of propionate, valerate, total volatile fatty acids, and ammonia-nitrogen; and the rumen pH after a 24 h fermentation. By contrast, DF addition decreased the ratio of acetate to propionate and the concentrations of lactate, lipopolysaccharide, methylamine, tryptamine, putrescine, histamine, and tyramine (P < 0.05). Principal coordinates analysis and molecular variance analysis showed that DF altered the ruminal bacterial community (P < 0.05). At the phylum level, DF decreased the proportion of Proteobacteria, and increased the proportions of Spirochaetae and Elusimicrobia (P < 0.05). At the genus level, DF decreased the percentage of Ruminobacter, while increasing the percentage of Succinivibrio and Treponema (P < 0.05). Overall, the results indicate that DF modified rumen fermentation and mitigated the production of several toxic compounds. Thus, DF has great potential for preventing subacute rumen acidosis in dairy cows and for improving the health of ruminants.
