植物精油在肉牛生产中的应用及其作用机制

Application and Mechanism of Plant Essential Oil on Beef Cattle Production

植物精油是从植物中提取的芳香油状液体,具有抗菌、抗氧化及消炎等作用。在全面禁抗的形势下,植物精油可以作为一种替代抗生素的天然饲料添加剂。植物精油在单胃动物上应用较多,但在肉牛上的研究比少,并且作用效果并不一致。本文就植物精油对肉牛生长性能、营养代谢、瘤胃发酵、甲烷产量和牛肉品质的影响及其相关作用机制进行综述,进一步挖掘植物精油在肉牛生产中的应用潜力。

Plant essential oil is an aromatic oil-like liquid extracted from plants,which has antibacterial,anti-oxidation and anti-inflammatory functions.Therefore,plant essential oil can be used as a natural antibiotic substitute under the circumstance of antibiotic prohibition in feed.There were many case studies with plant essential oil in monogastric animals,but relatively few studies in beef cattle,whose results suffered wants of uniformity.In this paper,the application and related mechanism of plant essential oil on growth performance,nutrition metabolism,rumen fermentation,methane production and beef quality of beef cattle were reviewed,so as to comprehensively understand the scientific application of plant essential oil in beef cattle production.
