了解膳食纤维 能够促进动物消化并提高饲喂水平

　　GLOBAL - The addition of fibre-degrading enzymes to feed delivers significant benefits for animal digestion, explains Dr Hadden Graham, Global Technical Director at AB Vista.Dietary fibre is commonly known as the part of the diet which is not broken down by the animal’s digestive enzymes. But in the latest of AB Vista’s Extraordinary Science Brought to Life videos, Dr Graham explains how a greater understanding of dietary fibre can help to optimise feed.“The major carbohydrate in any feed is generally the polysaccharides – this includes starch, as well as cellulose, hemicellulose, pectins and fructans: these last four make up the dietary fibre. For the purposes of analysis, dietary fibre can be defined as the sum of the non-starch polysaccharides and the lignin.”

　　AB Vista公司全球技术总监Hadden Graham称，在饲喂中加入消化纤维的酶，将对动物消化有巨大的益处。众所周知，膳食纤维作为饮食的一部分，不容易被动物体内的消化酶分解。但是，Graham博士在AB Vista公司发布的最新视频“走进生活的特殊科学”中谈到，更全面的理解膳食纤维有助于饲喂最优化。所有饲料中含有的碳水化合物主要是多糖，多糖包括淀粉、以及纤维素、半纤维素、果胶和果聚糖。后四种构成了膳食纤维。为了便于分析，可以把纤维定义成，一种无淀粉的多糖集合与木质素的综合体。
