Radiological studies of the alimentary tract in two Greek tortoises (Testudo graeca).

Barium sulphate was administered to two tortoises (Testudo graeca). Gastric emptying was not completed until 23 and 80 hours after barium administration and complete passage of barium through the gastrointestinal tract took 25 and 28 days. The consequences of these findings are discussed with reference to artificial feeding and medication regimes in chelonians.
