The mid- 2000s saw the rise of ractopamine as a prominent growth promoting agent for the meat industry. Suppliers in this industry are probably familiar with ractopamine, but manufacturers using meat in their products may not know much about its use and effects. We’ve pulled together the top 3 facts to know about ractopamine:
1. Ractopamine promotes lean muscle growth in the weeks prior to slaughter.
Ractopamine belongs to a class of drugs called beta adrenergic receptor agonists. These drugs mimic the effects of adrenaline, resulting in increased protein synthesis in muscle tissue during the administration period, which is typically a few weeks prior to slaughter. Ractopamine also increases feed efficiency, causing the livestock to grow at a more rapid rate while consuming less feed. This results in animals with a higher lean muscle to fat ratio, allowing farmers to be able to produce more lean meat on fewer natural resources.
