Abstract
Blood flow and its distribution was examined in summer and winter acclimatized normothermic and hyperthermic domestic hens. A clear trend of season on normothermic blood flow distribution was not noted; however, a significant tendency towards increased flow in summer was recorded. In 22 out of 28 organs or tissues examined, blood flow was lower in winter than in summer: pectoral muscle, adrenal and jejunum winter to summer ratios were 36, 64 and 76%, respectively (P less than 0.05). During hyperthermia, blood flow to visceral organ decreased in both groups; in summer this reduction was less severe in parts of the digestive system and more pronounced in parts of the reproductive system.
