摘　　要：植物提取物(PE)是提取于植物中且具有抗菌、抗氧化和免疫调节等1种或多种生物学功能的天然成分物质,可通过改善饲料适口性,增加动物采食量;促进消化液和消化酶分泌,调节肠道菌群并改善肠道生理形态和功能状态,从而促进营养物质消化吸收;促进生长激素(GH)、胰岛素样生长因子-1(IGF-1)和甲状腺激素(THs)分泌,调节机体生长和代谢;提供维生素D并促进成骨,维持骨组织生长,从而起到促进动物生长的作用。近年来,PE作为天然促生长饲料添加剂已成为国内外研究热点,而目前对PE的研究主要集中在对动物机体某一方面或某一功能的单一影响上。因此,本文针对PE促动物生长作用的机制进行系统综述,为PE的开发利用提供参考。Plant extracts(PE)are natural substances extracted from plants and have one or more biological functions such as antimicrobial,antioxidant and immunomodulation,which can increase animal feed intake by improving feed palatability;promote the secretion of digestive fluid and digestive enzymes,regulate intestinal flora and improve intestinal physiological morphology and functional status,thereby promoting the digestion and absorption of nutrients;promote growth hormone(GH),insulin⁃like growth factor⁃1(IGF⁃1),and thy⁃roid hormone(THs)secretion,regulate body growth and metabolism;provide vitamin D and promote osteo⁃genesis,maintaining bone tissue growth,thus promoting animal growth.In recent years,PE as a natural growth⁃promoting feed additive has become a research focus all over the world,and the current research on PE has largely focused on a single impact on a certain aspect or function of the animal bodies.Therefore,this arti⁃cle systematically reviews the mechanism of PE to promote animal growth,so as to provide reference for the development and utilization of PE and further reveal the molecular mechanism.
