Intravenous infusion of 0.5 mmol/kg B.W. to lambs aged eight to 14, 15 to 21, 22 to 28, and 29 to 35 days led to higher blood plasma levels of insulin and total alpha-amino-N. Rises were stronger and longer lasting after infusion of 1.25 mmol/kg B.W. of arginine. Blood plasma levels of glucose and free fatty acids were temporarily decreased in response to infusion. Infusion to lambs aged between eight and 14 days of 0.5 mmol/kg B.W. of glycin did not change insulin, glucose nor free fatty acids, though total alpha-amino-N was very slightly increased for very short time. Infusion of 1.25 mmol/kg B.W. of glycin proved less effective than that of arginine with regard to higher levels of insulin and total alpha-amino-N.
