Virginiamycin is widely used as a feed additive in livestock production to promote growth and improve feed efficiency. It is particularly effective in poultry, swine, and cattle, where it helps control Gram-positive bacteria that can negatively impact animal health and productivity. By inhibiting bacterial protein synthesis, it reduces the prevalence of infections and enhances overall animal performance. Additionally, it is employed in veterinary medicine to treat specific bacterial infections, contributing to better herd and flock management. Its use in agriculture supports sustainable farming practices by minimizing the need for higher doses of other antibiotics and reducing the risk of disease outbreaks.
