Adipose tissue capillary blood flow in relation to fatness in sheep

Abstract

Capillary blood flow rate was measured in eight fat depots in eight Blackface and eight Clun lambs using the radiolabelled microsphere technique. Adipose tissue flow ranged from 3 to 47 ml 100 g-1 min-1 depending upon depot and degree of fatness. Blood flow declined with increasing fatness suggesting that perfusion was not an important constraint on the growth of fat. Blood flow rates were also measured in the fed and 26 hour fasted states but no effect from fasting was observed.
