The effect of Clenbuterol and recombinant porcine Somatotropin (rpST) on the N and energy metabolism was tested by means of the respiration trial technique and compared with a control. In one experiment Clenbuterol was given per os on the nutrition level of three times energy maintenance requirement and in two experiments on the nutrition level 3.2 and 2.4 times energy maintenance requirement, rpST was injected s. c. The live weight gain of the treated animals was 9 % (Clenbuterol), 18 and 24 % (rpST) higher than that of the controls, protein energy deposition was 21 % (Clenbuterol), 45 and 46 % (rpST) higher and fat energy deposition was 14 % (Clenbuterol), 33 and 37 % (rpST) lower than that of the controls.
