半纯合日粮法测定几种麦类及红薯淀粉在生长猪体内的消化率
Study on Digestibility of Starch from Oat, Wheat, Buckwheat and Sweet Potato in Intestinal Tract of Growing Pigs by Feeding Semi-single Diet
摘要
Abstract
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.关键词
