ABSTRACT
Four wethers with chronic indwelling catheters in the portal, hepatic and mesenteric veins as well as in the abdominal aorta were housed in temperature-controlled rooms at 20ºC or 35ºC. The sheep consumed a diet at the level of maintenance requirements with both temperatures. Hepatic blood flow tended to be greater at 35ºC than 20ºC. The absorption of acetate and propionate as well as the oxygen uptake by the portal-drained viscera were significantly greater at 35ºC than at 20ºC. The increased oxygen uptake may be one cause of the heat load under hot temperature.
