Abstract: The experiment was conducted to determine the effects of different starch constituents (sticky rice, brown rice, corn, RS Hi-Maize1043) on the level of blood glucose and insulin of weaned piglets. The results showed that with the different starch constituents, the variation of blood glucose and inlusin of pigs is discrepant during the postprandial periods as the changing rate and the extent of bood glucose and insulin and the insulin/glucose ratio of sticky rice group is the greatst, while the brown rice group ranks the second, the corn group the third, and the RS group the least. Conclusion: the digestion and absorption of starch of different starch sources are different, in causing the different regulations of blood glucose. The slowly digested starch and RS were beneficial to maintain the steady-state of blood glucose and reduce the secretion of insulin.
