None:
Beta-adrenergic agonists (β-AA) enhance beef production efficiency, carcass leanness, and emissions intensity, offering consistent economic returns for cattle feeders and beef packers. Numerous research experiments have been published to quantify the effects of ractopamine hydrochloride, zilpaterol hydrochloride, and lubabegron fumarate on live gain and carcass characteristics. β-AA response remains additive with other growth-enhancing technologies and incrementally improves growth performance, carcass merit, sustainability, and profitability late in the feeding period (last 14-91 days).

Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
