title: Celiac cyclic blood flow pattern response to feeding and heat exposure.
abstract: Male broilers (3.0 to 3.4 kg) chronically implanted with an electromagnetic blood flow probe on the celiac artery were used to study the effect of feeding and heat exposure on celiac mean blood flow (MBF). Postprandial celiac MBF and a cyclic pattern of MBF, produced in response to feeding, were reduced (P less than .05) by a 60-min exposure to 37 C but returned during a thermoneutral (25 C) recovery period. The exact nature of this cyclic MBF phenomenon is unknown but may be related to intestinal smooth muscle activity alterations and sympathetic vasomotor tone.
