Potency of ginkgo fruit for modulation of rumen microbiota and fermentation

摘要

Enteric methane is produced by methanogenic archaea in gastrointestinal tract of ruminant animals during their feed utilization, which closely related to greenhouse gas emission and loss of energy in feed stuff Therefore, methane reduction has been attempted by the use of rumen modulating agents including antibiotics. Although ionophore antibiotics have exhibited beneficial effect on rumen fermentation and animal performance, use of these additives have been gradually prohibited due to concerns on public health. The use of “natural” sources may not be subject to concerns raised regarding the overuse of chemically- and biologically- synthesized antibiotics including ionophores. Many plant-derived compounds have been paid attention as a safer additive candidate for modulating rumen fermentation. Salicylate, its derivatives，flavonoids and terpenoids have been reported to possess different extents of antimicrobial function.
