| Abstract: | Transport of glucose was measured in the intestine of white leghorn layers in vivo using ligated upper small intestinal segment in the presence of Ca2+ and other ions either singly or in combination. Transport of glucose across the intestine was very significantly increased with Ca2+ than Na+, K+ and Po4(3-) individually, but when Ca2+ was combined with Na+, K+ and PO4(3-), the glucose absorption increased significantly over that achieved by Na+ ions alone. These data revealed that Ca2+ ions might be exerting the major influence on glucose transport processes of the chicken intestine. |
