title: Effect of fasting on capillary blood flow in sheep.
abstract: Capillary blood flow rate was measured in 29 tissues in two hourly fed and 26 hour fasted Blackface and Clun lambs using the radiolabelled microsphere technique. Blood flow declined with fasting in alimentary tract, skin of the ear and some of the larger skeletal muscles. It was concluded that capillary perfusion in nerve tissue was not affected by fasting whereas tissues principally responsible for energy absorption, expenditure and retention can experience a fall in capillary blood flow during fasting.
