Internal pressure of the bag was maintained at\n2 mm Hg by use of an electronic barostat, and\nchanges in bag volume were recorded before, during,\nand after horses consumed diets of grain or hay. Each\nhorse was fed 0.5 and 1.0 g of grain\/kg and 0.5 and 1.0\ng of hay\/kg. Changes in bag volume measured by use\nof the barostat were indirectly related to changes in\ntone of the gastric wall.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results<\/jats:bold>\n                    \u2014Food intake caused a distinctly significant\nbiphasic increase in volume. The first phase was during\nactive ingestion, which was followed shortly by a\nsecond, more prolonged postprandial phase. The\ningestion-related phase of the response to intake of a\ndiet of 1 g of hay\/kg was significantly greater than that\nfor the other diets.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusion and Clinical Relevance<\/jats:bold>\n                    \u2014Ingestion of a\nsolid meal induces a biphasic relaxation response in\nthe proximal portion of the stomach of horses.\nMagnitude of the ingestion-related phase may be\ndetermined by size of the meal.
