摘要
植物提取物中的挥发油、皂苷、生物碱、萜类等化学物质具有抗菌、促生长、提高免疫力和抗氧化等功能。近年来研究发现,植物提取物还可以调控反刍动物瘤胃发酵模式,提高氮存留,减少甲烷排放的功能,因此,植物提取物作为调控反刍动物瘤胃发酵的一种重要添加剂得到了广泛的研究与应用。目前国内外的学者已经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。文中就目前植物提取物对反刍动物瘤胃发酵调控的最新研究进展作一综述,为我国开展植物提取物作为反刍动物瘤胃发酵调控添加剂的研究提供参考。
The essencial oil, saponin, alkaloids, terpenoid and other compostion in plant extract have function of growth promotion, improve immunity, anti-oxidiation and so on when feed to unistomach an- imals. Research during recent years also discovered that plant extracts can manipulate rumen fermenta- tion pattern, improve nitrogen reservation, decrease methane release when feed to ruminants. Therefore, plant extracts are widely studied and applied as an important feed additive to regulate rumen fermenta- tion of ruminant animal. Until recently, great progrss has been made in selection of effective plant species, function mechanism revelation, and dose effect of plant extract, in this aticle, research progress of plant extract was reviewed, aimed to supply reference for utiliztion of plant extract to manipulate ru- men metanbosim.
