Metabolic modifiers are commonly used in global food animal production to improve the efficiency of meat production and to improve end-product composition. The primary compounds used include steroid hormone implants, widely used in cattle and sheep, and beta-adrenergic agonists, fed to cattle and swine. Use of these compounds can improve production efficiency by as much as 40% and provides improved economic returns for livestock producers and reduced environmental impact for society due to improved efficiency of nutrient utilization. Use of these compounds within label directions is safe for animals and the meat produced is safe for human consumption.
