本文研究了燕麦、小麦、荞麦和红薯4种原料中淀粉(总淀粉、直链和支链淀粉、抗性和非抗性淀粉)含量及其在生长猪回肠末端和全消化道(粪)的消化率,为丰富能量饲料数据库、合理利用能量饲料原料以及人类自身对膳食的选择提供参考.实验选择体重为25±2.72 kg的杜×长×大三元杂交生长阉公猪16头,实施"T"型瘘管手术,随机分为4个处理(燕麦、小麦、荞麦和红薯),每个处理4个重复,每个重复1头猪,分别饲喂燕麦、小麦、荞麦和红薯单一日粮.结果显示,在回肠末端和全消化道内,各日粮总淀粉的消化率分别是:燕麦组:98.86%和99.95%;小麦组:99.48%和99.92%;荞麦组:99.37%和99.97%;红薯组:81.60%和99.51%.三组麦类淀粉在回肠和全消化道中的消化率差异不明显,但均显著高于红薯组(p<0.05).结果表明,麦类饲粮在生长猪体内的消化率及其葡萄糖供给效率高,是较红薯更好的能量饲料来源.

This experiment was conducted to determine the digestibility of starch from oat, wheat, buckwheat and sweet potato for enriching the data bank of energy diets and offering people more references about main foods. 16 crossed-bred (Duroc×Landraee×Yorkshine) growing pigs weighed average of 25 kg, were randomly assigned to four groups and housed individually in pens. And the T-canales fistulae operation was carried on each pig. Every group fed one of four diets containing minerals, vitamins, 0.1% indicator (TiO2) and oat, wheat, buckwheat, and sweet potato starch respectively. The formal experiment lasted 15 days. In last 3 days, the digesta and feces of all pigs were collected for digestibility analyzing. The results showed that the digestibility of starch from oat, wheat, and buckwheat were higher than that from sweet potato (p<0.05). It was indicated that so far as starch digestibility was considered, oat, wheat, and buckwheat were better diet energy sources than sweet potato.
