✦ Synopsis

The effects of gonadal steroids and adrenergic agonists in growing poultry are reviewed. Estrogens, used commercially to caponize, improve muscle palatability and weight gain but are hyperlipidemic and adversely affect feed efficiency. Their ability to caponize results from the fact that negative feedback regulation of gonadotropin secretion is mediated by estrogen synthesized within the male's central nervous system. Androgens are strongly anabolic in avian species but are deleterious to growing bone. Thus, androgens depress growth and efficiency when given before epiphyseal closure but stimulate gain and improve efficiency when given afterwards. The beta-adrenergic agonist clenbuterol improves the growth and efficiency of broiler chickens. The effects of beta-agonists on muscle, adipogenic tissue, and the endocrine system are presented as possible mechanisms for these actions.

## Abstract ## Objectives: Inhaled medications prescribed for the hypersensitive airway typically combine corticosteroids and long‐acting Ξ²2 adrenergic agonists (LABAs). The phonatory side effects of these combination treatments are widely recognized. However, there is limited understanding of the
