| 摘 要： | 以60日龄生长猪为动物模型,考察4种不同杂粮原料中淀粉(总淀粉、直链和支链淀粉、抗性和非抗性淀粉)的含量及其在生长猪回肠末端和粪中的表观消化率。结果表明:以干物质为基础,各种杂粮淀粉的含量因杂粮种属不同而差异较大。芋头淀粉和木薯淀粉的回肠末端消化率均显著高于(P<0.05)土豆和山药淀粉;所有淀粉在粪便中的表观消化率均达99%以上。芋头淀粉和木薯淀粉因回肠末端消化率高而具有较高的葡萄糖供给效率,土豆淀粉和山药淀粉因后肠微生物的发酵而利用率升高。

| Abstract: | Piglets of 60 days old were used as the animal model to evaluate in vivo apparent digestibility of starch of different coarse cereals such as taro,potato,Chinese yam and cassava.Results indicated that starch content varied in different species of coarse cereals.The apparent digestibility of taro and cassava starches in ileal digesta was significantly higher(P<0.05) than that of potato and Chinese yam starches.The apparent digestibility of starches of all the coarse cereal species in faeces reached up to 99%... |
