The portal blood flow and the oxygen consumption by <jats:styled-content style=\"fixed-case\">PDV<\/jats:styled-content> linearly increased at increased organic matter (<jats:styled-content style=\"fixed-case\">OM<\/jats:styled-content>) intake. No effect of level of <jats:styled-content style=\"fixed-case\">OM<\/jats:styled-content> intake was obtained for the hepatic artery blood flow and oxygen consumption by liver. As a consequence, the level of <jats:styled-content style=\"fixed-case\">OM<\/jats:styled-content> intake only tended to directly affect hepatic blood flow and oxygen consumption by total <jats:styled-content style=\"fixed-case\">ST<\/jats:styled-content>. Oxygen consumption was linearly and positively related to blood flow across <jats:styled-content style=\"fixed-case\">PDV<\/jats:styled-content>, liver and total <jats:styled-content style=\"fixed-case\">ST<\/jats:styled-content>. The heat production by <jats:styled-content style=\"fixed-case\">PDV<\/jats:styled-content> and total <jats:styled-content style=\"fixed-case\">ST<\/jats:styled-content>, as proportion of metabolizable energy (<jats:styled-content style=\"fixed-case\">ME<\/jats:styled-content>) intake, decreased curvilinearly at increased <jats:styled-content style=\"fixed-case\">ME<\/jats:styled-content> intake. In conclusion, the oxygen consumption by <jats:styled-content style=\"fixed-case\">PDV<\/jats:styled-content>, but not by liver, was directly related to the level of forage intake by sheep.
