  • Compositions for reducing gastro-intestinal methanogenesis in ruminants
    Patent number: 8771723
    Abstract: The present invention concerns the reduction of gastro-intestinal methanogenesis in ruminants with the aid of agents that compete for the hydrogen atoms required by methanogens during normal fermentation of ingested feed. The invention in one aspect resides in the findings that both nitrate reductive pathways as well as sulphate reductive pathways outcompete gastro-intestinal methanogenesis in ruminants and, that the methanogenesis reducing effects of nitrate and sulphate are completely additive. At the same time the combined administration of nitrate and sulphate was found to be fully effective to avoid or mitigate the potential problems of nitrite intoxication normally encountered when using nitrate alone, which effect is further enhanced, where necessary, by the addition of a nitrite reducing probiotic micoroorganism.
