Outline of Final Research Achievements |
Methane mitigation potential of alkylphenol-containing plants such as ginkgo fruit (GF) and cashew nut shell liquid (CL) was evaluated by the application as manure and/or feed additive. Considering local availability of each material, GF was supposed to use for Japanese cattle, while CL was for native cattle and swamp buffaloes in Thailand. The evaluations were made by monitoring changes of fermentation products and microbiota in in vitro culture systems and also in feeding studies. Both materials decreased methane production potential by the direct addition to feces with significant alteration of fecal microbial community, based on the selective anti-microbial actions. CL was further evaluated by feeding studies using Thani animals and was found to decrease methane production not only from the rumen fluid but also from feces. This accompanied with apparent changes in fecal microbiota.
