Zilpaterol hydrochloride (Cat No.: M025811) is a β-adrenergic agonist used as a feed additive to promote muscle growth and improve feed efficiency in cattle, particularly during the finishing phase before slaughter. It enhances lean meat yield by stimulating β2-adrenergic receptors, leading to increased protein synthesis and reduced fat deposition. Administered under strict veterinary guidance, zilpaterol is typically withdrawn before processing to ensure food safety. Its use is regulated or prohibited in several countries due to concerns about animal welfare and potential residues in meat.
