Abstract

This study was conducted to determine starch contents and the digestibilities of terminal ileum and total digestive tract for four starch sources from millet, corn, stick rice and long shaped rice in growing pigs. Sixteen crossed bred  (Landrace× Yorkshire × Duroc) barrows with an average body weight (BW) of (25±2.72) kg were randomly allocated to four dietary treatments on the basis of BW and litter origin in a randomized complete block design. The dietary treatments were millet group, corn group, stick rice group and long shaped rice group, respectively. All pigs were surgically fitted with a simple T-cannula at the terminal ileum. The experiment lasted for 7 days. Results showed that the starch digestibilities of the terminal ileum and total digestive tract were 99. 31% and 99.88% in millet group, 100% and 100% in stick rice group, 99.37% and 100% in the long shaped rice group, which were all higher than 98.26% and 99.80% in the corn group ( P<0.05). These results indicated that the four cereal starches could supply pigs with more glucose in the terminal ileum because of their high digestibilities.
