Nosiheptide, also known as Multhiomycin, is primarily used as a feed additive in the agricultural industry to promote growth and improve feed efficiency in livestock, particularly in poultry and swine. Its antibacterial properties help control pathogenic bacteria in the gut, enhancing animal health and productivity. Additionally, it is used in veterinary medicine to treat bacterial infections in animals. Its low absorption rate in the gastrointestinal tract makes it a safe and effective option for long-term use in animal feed. Research is also exploring its potential in human medicine due to its unique mechanism of action against antibiotic-resistant bacteria.
