Plasma Glucagon Concentrations in Sheep: Their Regulation and Relation to Concentrations of Insulin and Growth Hormone

Abstract

A radioimmunoassay for glucagon has been used to study the regulation of the plasma glucagon concentration in sheep. The mean plasma glucagon concentra· tion after an overnight fast was 0·20 ng/ml in crossbred sheep and 0 ·12 ng/ml in Merinos. During a more prolonged fast plasma glucagon concentrations declined.
