摘要
随着抗生素应用越来越受到限制,应用植物提取物对反刍动物营养进行调控成为了研究热点。生物碱类、鞣质、皂苷、精油、萜类以及黄酮类等植物提取物具有抑菌、改善瘤胃发酵和预防瘤胃酸中毒等作用,是理想的抗生素替代物。目前在有效植物品种的筛选和植物提取物作用机理、剂量效应等方面的研究取得了较大进展。本文对应用于反刍动物饲料的植物提取物的种类、来源及其在反刍动物营养调控方面的研究进行了综述,提出了当前植物提取物应用中存在的问题,并对其应用前景进行了展望,以期为我国开展植物提取物作为抗生素替代物调控反刍动物瘤胃酸中毒的研究提供参考。
Along with the limitation of using antibi otics,the studies of applying plant extract into ruminant feeding have been paid more attention.Alkaloids,tannins,saponins,essential oils,terpenoids and flavonoids have the functions of antibacterial,improving rumen fermentation and preventing rumen acidosis.They were served as the substitute of antibiotics.At present,the research in screening effective plant species,the mechanism of plant extracts and dose effects have made great progress.This paper summarized the types and sources of plant extract,as well as the research of manipulation in ruminant nutrition.The problems of plant extract in application were put forward and the expectation of application were prospected,in order to provide references for the research of plant extract as the substitute of antibiotics in rumen acidosis.
