摘要

In the last five decades,attempts have been made to improve rumen fermentation and host animal nutrition through modulation of rumen microbiota.The goals have been decreasing methane production,partially inhibiting protein degradation to avoid excess release of ammonia,and activation of fiber digestion.The main approach has been the use of dietary supplements.Since growth-promoting antibiotics were banned in European countries in 2006,safer alternatives including plant-derived materials have been explored.Plant oils,their component fatty acids,plant secondary metabolites and other compounds have been studied,and many originate or are abundantly available in Asia as agricultural byproducts.In this review,the potency of selected byproducts in inhibition of methane production and protein degradation,and in stimulation of fiber degradation was described in relation to their modes of action.In particular,cashew and ginkgo byproducts containing alkylphenols to mitigate methane emission and bean husks as a source of functional fiber to boost the number of fiber-degrading bacteria were highlighted.Other byproducts influencing rumen microbiota and fermentation profile were also described.Future application of these feed and additive candidates is very dependent on a sufficient,cost-effective supply and optimal usage in feeding practice.
