Number of multinucleated cellular units or muscle fibers is fixed at birth. Increasing muscle hypertrophy has been a primary focus of investigators. Beta-adrenergic agonists increase muscle mass by increasing the ratio of protein to deoxyribonucleic acid (DNA), while steroidal implants increase muscle mass by increasing accumulation of DNA in muscle. Beta-adrenergic agonists and steroidal implants have similar physiologic responses of muscle hypertrophy, but have different mechanisms of action to achieve muscle growth. Beta-adrenergic agonists suppress adipose accretion in livestock species. Cattle has more than 99% of beta-2 adrenergic receptor in the skeletal muscle and has more than 90% of beta-2 adrenergic receptor in adipose tissue, whereas pig has 73% of beta-1, 20% of beta-2 and 7% of beta-3 adrenergic receptors.
