What the data say about Beta-Agonists

Written by: Jacquelyn Prestegaard

Beef and pork producers are well aware of the increasing global demand for their product. They also know their feed and land resources are exponentially shrinking. For them, modern agricultural technologies are a necessity to keep reasonably priced meat on consumers’ plates.

One of these essential technologies comes in the form of beta-adrenergic agonists, commonly referred to as beta-agonists or BAA’s. Beta-agonists are feed additives given to market hogs and cattle to maximize feed efficiency. They work by more effectively converting feed intake to lean muscle growth.

BAA’s come in two forms: Zilpaterol Hydrochloride (Zilmax), used exclusively in cattle, and Ractopamine Hydrochloride, used in both cattle and swine (Optaflexx and Paylean, respectively). Because they so dramatically improve animal growth, the use of these feed additives raise many questions from consumers and producers alike. Read more
