Description

Oxytetracycline is a broad-spectrum antibiotic belonging to the tetracycline class, valued for its efficacy against a wide range of Gram-positive and Gram-negative bacteria, as well as other microorganisms. Its primary commercial value lies in its extensive use in veterinary medicine, agriculture, and aquaculture for disease prevention and treatment. This makes it a critical raw material for manufacturers of animal health products, feed additives, and agricultural formulations targeting global markets.

Application

• Veterinary Medicine: A key active pharmaceutical ingredient (API) in injectable solutions, oral powders, and premixes for treating bacterial infections in livestock, poultry, and companion animals.
• Aquaculture: Used in medicated feeds to control and prevent bacterial diseases in farmed fish and shrimp, promoting stock health and yield.
• Animal Feed Additive: Incorporated at sub-therapeutic levels as a growth promoter to improve feed efficiency and weight gain in food-producing animals.
• Agricultural Use: Applied for the control of certain bacterial plant diseases, such as fire blight in fruit trees.
• Pharmaceutical Intermediates: Serves as a starting material or intermediate in the synthesis of other tetracycline-derived pharmaceuticals.
• Research & Development: Utilized in microbiological laboratories as a standard antibiotic in culture media and for antimicrobial susceptibility testing.
