Description

Tylosin is a macrolide-class antibiotic produced by *Streptomyces fradiae*, widely recognized for its efficacy against Gram-positive bacteria and mycoplasmas. Its primary commercial value lies in its critical role in veterinary medicine for promoting animal health and growth. This makes it an essential raw material for manufacturers of premixes, feed additives, and pharmaceutical formulations targeting livestock, poultry, and swine industries globally.

Application

• Veterinary Pharmaceutical Formulations: Used as an active pharmaceutical ingredient (API) in injectables, soluble powders, and tablets for treating respiratory and enteric infections in animals.
• Feed Additive and Growth Promoter: Incorporated into animal feed premixes to prevent disease and improve feed efficiency in poultry, swine, and cattle operations.
• Mycoplasma Control: Particularly effective in controlling chronic respiratory disease in poultry and mycoplasmal pneumonia in swine.
• Aquaculture: Employed in the treatment of bacterial infections in farmed fish and shellfish.
• API for Generic Veterinary Drugs: Serves as a key starting material for manufacturers producing generic veterinary antibiotic products.
• Research and Development: Used in microbiological research and as a reference standard in analytical laboratories.

Quality Control

Our Tylosin is produced under strict quality management systems to ensure batch-to-batch consistency and reliability. Quality is verified through comprehensive analytical testing, including HPLC for potency and related substances, microbial limits testing, and residual solvent analysis. A Certificate of Analysis (COA) documenting purity, identity, and other critical parameters is provided with each shipment to support your regulatory and production needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to degradation or caking.
