Across decades of research, implants consistently improve growth: suckling calves gain roughly 6% to 15% more ADG and wean about 10.4 kg heavier, while backgrounded cattle commonly realize 14% to 16% greater ADG. Administering a single calf...

Beta-adrenergic agonists (β-AAs) are synthetic compounds structurally related to catecholamines that activate β-adrenergic receptors (β-ARs), thereby stimulating intracellular signaling cascades, most notably the cAMP-PKA pathway. In liv...

Implant effects on growth are typically well understood, while behavioral (ie, riding) carcass-quality (ie, marbling or reduction in dairy-type muscling) are more variable. A newer challenge related to implant use is recent Food and Drug Ad...

Steroidal implants are widely used in global beef production to enhance growth and efficiency. These implants, classified by potency and coating type, release anabolic hormones such as androgens and estrogens over an extended time course of...
