植物提取物对高精料饲粮下反刍动物瘤胃功能、微生物区系和炎症反应的调控效果

Regulation Effects of Plant Extracts on Rumen Function,Microflora and Inflammatory Response in Ruminants under High-Concentrate Diet

为提高反刍动物生产性能,满足其营养需求,实际生产中生产者常常使用高精料饲粮饲喂反刍动物。反刍动物长期饲以高精料饲粮会导致瘤胃微生物区系改变,引起瘤胃发酵和代谢紊乱,进而影响动物健康。植物提取物具有调节瘤胃微生物区系、改善瘤胃发酵和代谢的作用。本文综述了植物提取物对高精料饲粮下反刍动物瘤胃功能、微生物区系和炎症反应的影响及作用效果。

In order to improve the performance of ruminants and meet their nutritional needs, producers often use high concentrate diets in practical ruminant production. Long term feeding of high concentrate diets can lead to changes in the rumen microflora and disorders in rumen fermentation and metabolism, which in turn af fects animal health. Plant extracts have the effects of regulating the rumen microflora, improving rumen fer mentation and metabolism. This paper reviewed the effects of plant extracts on rumen function, microflora and inflammatory response in ruminants under high concentrate diets.
