Biliary response to food in chickens with intact or interrupted enterohepatic circulation.

The biliary secretion in response to food has been studied in chicken. In this species, a well defined biliary postprandial response with a clear vesicular component can be estimated. The bile salt independent fraction increases after feeding. Our results show that gallbladder bile has a lower osmotic power. The biliary response to food when the enterohepatic circulation is blocked, diminishes. The relationship between bile salt independent fraction values, whether the vesicular duct is tied or not, remains constant when the enterohepatic circulation is interrupted.
