Effects of Insulin and Gastro-Intestinal Hormones on Feeding and Plasma Insulin Levels in Sheep

This is the authors' abstract. We don't add key points for this paper.

Infusions of the following hormones were made into the hepatic vein of sheep over periods of three hours: pentagastrin (2.1, 5.0 or 9.9 micrograms/kg), pancreozymin (1.0 units/kg), secretin (2.0 units/kg), insulin (2.1 or 4.3 units/kg). Intake of the concentrate food was depressed by pentagastrin at 9.9 micrograms/kg/3 hr (P < 0.05) and increased by insulin at 4.3 units/kg/3 hr-(P < 0.05) Insulin levels in jugular plasma were unaffected by any of the gut hormone infusions. The liver is suggested as being involved in the control of food intake in sheep.
