Nutritional and Physiological Constraints Contributing to Limitations in Small Intestinal Starch Digestion and Glucose Absorption in Ruminants

Increased efficiency of nutrient utilization can potentially be gained with increased starch digestion in the small intestine ruminants. However, ruminants have quantitative limits extent disappearance intestine. The objective is to explore nutritional and physiological constraints that contribute limitations carbohydrate assimilation ruminant Altered digesta composition passage rate intestine, insufficient pancreatic α-amylase and/or intestinal carbohydrase activity, reduced glucose absorption could all limiting factors assimilation. absence sucrase activity may related hydrolysis. Multiple sequence alignment sucrase-isomaltase complex gives insight into potential molecular mechanisms associated capacity for digestion, feed cattle sheep. Future research efforts these areas will aid our understanding optimize feeding strategies meat milk production efficiency.
