摘要：
The present invention concerns the reduction of gastro-intestinalmethanogenesis in ruminants with the aid ofagents that compete for the hydrogen atoms required by methanogens duringnormal fermentation of ingested feed. The inventionin one aspect resides in the findings that both nitrate reductive pathways aswell as sulphate reductive pathways outcompete gastro -intestinalmethanogenesis in ruminants and, that the methanogenesis reducing effects ofnitrate and sulphate are completely additive.At the same time the combined administration of nitrate and sulphate was foundto be fully effective to avoid or mitigatethe potential problems of nitrite intoxication normally encountered when usingnitrate alone, which effect is further enhanced,where necessary, by the addition of a nitrite reducing probiotic . Hence,products are provided comprising highamounts of a combination of a nitrate compound and a sulphate compound andoptionally a nitrite reducing probiotic microorganism,as well as methods of reducing gastro-intestinal methanogenesis in ruminantsusing such compositions.
