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.
