[Gastro-entero-pancreatic production and hepatic uptake of gastrin and somatostatin in the preruminant calf receiving milk proteins or milk serum].

In preruminant calves total splanchnic production of immunoreactive somatostatin and gastrin did not change when casein was replaced by whey protein in the diet, but gastrin secretion was more rapid for the first 3 postprandial hours. Loss during passage through the liver was equivalent to splanchnic production for somatostatin, but was very low for gastrin.
