Description

Calcium Oxytetracycline is a calcium complex of the broad-spectrum tetracycline antibiotic, oxytetracycline. This formulation offers enhanced stability and bioavailability, making it a critical active pharmaceutical ingredient (API) for veterinary and agricultural applications. It is primarily used by manufacturers in the animal health, aquaculture, and feed additive industries to formulate products that combat bacterial infections and promote growth.

Application

• Veterinary Pharmaceuticals: A key API in injectable solutions, oral powders, and premixes for treating respiratory, gastrointestinal, and systemic bacterial infections in livestock, poultry, and companion animals.
• Aquaculture Feed Additives: Incorporated into medicated feeds to prevent and control bacterial diseases such as furunculosis in fish and other farmed aquatic species.
• Animal Growth Promoters: Used at sub-therapeutic levels in feed to improve feed efficiency and promote healthy growth in food-producing animals.
• Topical Veterinary Preparations: Used in ointments, creams, and sprays for treating localized bacterial skin infections and wounds in animals.
• Apiculture (Beekeeping): Employed for the control of American and European foulbrood, serious bacterial diseases affecting honeybee colonies.
• Agricultural Bactericides: Formulated for the protection of certain high-value crops against bacterial pathogens, though use is highly regulated.
