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)的含最及其在生长猪回肠末端和炎中的表观消化率.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.
以60 日齡生長豬為動物模型,攷察4種不同雜糧原料中澱粉(總澱粉、直鏈和支鏈澱粉、抗性和非抗性澱粉)的含最及其在生長豬迴腸末耑和炎中的錶觀消化率.結果錶明:以榦物質為基礎,各種雜糧澱粉的含量因雜糧種屬不同而差異較大.芋頭澱粉和木藷澱粉的迴腸末耑消化率均顯著高于(P<0.05)土豆和山藥澱粉;所有澱粉在糞便中的錶觀消化率均達99%以上.芋頭澱粉和木藷澱粉因迴腸末耑消化率高而具有較高的葡萄糖供給效率,土豆澱粉和山藥澱粉因後腸微生物的髮酵而利用率升高.

Piglets of 60 days old were used as the animal model to evaluate in vivo apparent digestibifity 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%.These investigations suggest that taro and cassava starches could supply piglets more glucose when digested in small intestine due to higher digestibility.Higher digestibility of potato and Chinese yam starches in feces could be resulted from the co-fermentafion of microorganisms in hindgut of piglets.
