Methane has been proven the second most commonly occurring greenhouse gas. Ruminants have been blamed for substantially contributing to methane emissions. Supplementation with tea saponin (TS) effectively decreased methane emissions and nitrogen emissions. It is not only beneficial for environmental protection, but also has potential economic benefits %K methane emissions %K nitrogen balance %K reduction strategy %K rumen fermentation %K microbial flora %K tea saponins %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6356566/
