植物精油调控反刍动物瘤胃发酵和甲烷排放的研究进展

Research Progress of Essential Oils Regulating Rumen Fermentation and Methane Emission in Ruminants

植物精油是一类从植物中萃取出来的具有芳香气味的油状液体,具有广谱抗菌性,对革兰氏阳性菌和革兰氏阴性菌均有一定的抑制作用。植物精油可减少反刍动物瘤胃中蛋白质的降解,降低其氨排放量,从而调控瘤胃中的氮代谢。植物精油在抑制反刍动物肠道甲烷排放方面表现出积极作用,具有作为饲料添加剂来调控瘤胃发酵的潜质。该文旨在阐述植物精油对瘤胃发酵和甲烷排放的调控作用,探讨其在生产中广泛应用的可行性。

Essential oil is a kind of oily liquid extracted from plants with aromatic odor.It has broad-spectrum antibacterial properties and can inhibit Gram-positive and Gram-negative bacteria.In recent years,studies have found that essential oils can reduce protein degradation in rumen and reduce ammonia emissions,thereby regulating nitrogen metabolism in the rumen.And studies have shown that essential oils play a positive role in suppressing intestinal methane emissions from ruminants,and have the potential to be used as feed additives to regulate rumen fermentation.The purpose of this article is to explain the regulation effect of essential oil on rumen fermentation and methane emission,and to explore the feasibility of its wide application in production.
