中文摘要：
动物养殖业目前面临着疾病、应激等各种不良因素的影响,添加抗生素等方法会导致肠道菌群失衡、药物残留和耐药性等多方面负效应,存在着威胁食品安全等诸多问题和潜在风险。因此,开发新型绿色饲料添加剂是畜牧业可持续发展的必然趋势。植物精油是从植物不同组织如果实、叶片、花和根中提取的具有强烈的气味和香味的挥发性液体,是一种＂高效、安全、稳定、可控＂的植物源性药物,具有抗菌、抗病毒、抗寄生虫、抗真菌、增强动物机体免疫机能、提高动物抗应激能力及改善动物生产性能等优点,是目前新型饲料添加剂研发的重点和热点之一。其作为抗生素的替代品运用到畜禽生产上具有很大的潜力。作者综述了植物精油的研究现状,包括其在抗菌、促生长、抗氧化、增强免疫力等方面的作用,旨在为植物精油生理功能的研究与应用提供参考。
英文摘要：
The animal breeding industry is faced with a variety of adverse factors such as disease, stress and the negative effects of using antibiotics,like intestinal flora imbalance,drug residues and resistance.These influences have become a threat to food safety,and cause many other issues and potential risks.Therefore,the development of new green additive is inevitable for the sustain-able development of animal husbandry.Essential oil is a kind of volatile liquid which is extracted from different organizations of plants such as fruit,root,leaf or flower,with strong fragrance and sweet smell.Essential oil is regarded as an “efficient,safe,stable and controllable”plant-derived drug,it has the functions of antibacterial,antiviral,anti-parasite,antifungal,enhancing the animal immune function,anti-stress ability and improving animals production performance,etc.Essential oil is one of the focus and hot spot of current research and development,it can be used as a substi-tute for antibiotics in the production of livestock and poultry.This review summarized the re-search status of essential oils,focused on their functions about antibacterial,growth promoting, anti oxidation and immunity enhancement.It is wished to prove reference for the research and ap-plication of essential oil.
