Inhibition of Methane Production by Plant Secondary Compounds in Ruminants
摘要
As a by-product of ruminants’ enteric fermentation, methane contributes significantly to greenhouse gas emissions and climate change and also results in a loss of approximately 2–12% of gross energy taken from feed. Secondary compounds found naturally in plants as defense mechanisms have been shown to reduce greenhouse gas emissions from livestock and promote sustainable livestock production. This study looked at the efficacy and practicality of using these compounds without adversely impacting animal performance and health as feed additives or dietary supplements. In this study, secondary compounds from terrestrial and marine plants are investigated in relation to enteric methane and related studies are summarized. To date, studies have shown that secondary plant compounds can reduce methane production. It is necessary to conduct more research on these compounds in order to optimize their efficacy, safety, and effectiveness.
