Description

Tylosin is a macrolide antibiotic produced by *Streptomyces fradiae*, widely recognized for its efficacy against Gram-positive bacteria and mycoplasmas. Its primary commercial value lies in its application as a veterinary therapeutic and feed additive to promote growth and prevent disease in livestock. This makes it a critical compound for the animal health, veterinary pharmaceutical, and feed manufacturing industries globally.

Application

• Veterinary medicine for the treatment of respiratory and enteric infections in swine, poultry, and cattle.
• Growth promoter and feed additive in animal nutrition to improve feed efficiency.
• Active Pharmaceutical Ingredient (API) in the formulation of injectable solutions, premixes, and soluble powders.
• Control and prevention of mycoplasmal infections in poultry (e.g., Chronic Respiratory Disease).
• Use in apiculture for the control of American and European foulbrood in honeybees.
• Intermediate in the synthesis of other veterinary antibiotic compounds.
