Effects of growth hormone on tissue metabolism in broiler chicks

Abstract
1. The effect of bovine growth hormone (GH) on cartilage, liver, muscle, pancreas and spleen has been investigated. 2. Tissue RNA was elevated in the liver, muscle and spleen of the GH-treated chicks while uptake of radioactive phosphate into RNA was stimulated for both liver and spleen. 3. The GH-treated chicks had an increased cartilage protein content together with a higher rate of incorporation of 14C-methionine pancreatic protein.
