Monensin sodium salt is widely used in the livestock industry as an antibiotic and feed additive. It is particularly effective in controlling coccidiosis, a parasitic disease that affects poultry and cattle. By inhibiting the growth of harmful protozoa, it promotes healthier growth and improves feed efficiency in animals. Additionally, it is used in ruminants to modulate gut microbiota, enhancing the production of propionic acid, which improves energy utilization and reduces methane emissions. In research, it serves as a tool to study ion transport mechanisms due to its ability to selectively bind and transport sodium ions across cell membranes. Its application in biotechnology includes its use as an antibiotic in cell culture media to prevent bacterial contamination.
