The present work aims mainly to study the effects of the beta adrenergic agonist clenbuterol (Cl) as a growth promoter on heart weight in avian 48 broiler chicks.

A significant increase was recorded in heart weight, histologically proved to be hypertrophy accompanied with inflammation endocarditis.
