Extract

Clenbuterol, a β adrenergic agonist, acts as a repartitioning agent increasing the ratio of protein to fat in the carcass. Recent reports on the action of clenbuterol in the bovine have indentified the repartitioning action but body composition has been estimated from sample joints and regression equations based on untreated cattle. Such data may not be appropriate for use with animals treated with repartitioning agents. A comparative slaughter experiment was designed to study the effects of clenbuterol on body composition and energy content of weight gain in the bovine. Veal calves were chosen as the model since they exhibit rapid weight gain, and in the latter stages of growth, prior to slaughter, a high proportion of the gain is fat; such animals may therefore be sensitive to the effects of a repartitioning agent.
