E713 – Tylosi
AntibioticDescription
Mixture of tylosin A, B, C, and D, produced by Streptomyces fradiae; macrolide antibiotic
Notes
Tylosin is part of a group of antibiotics called macrolides, and it's produced by fermenting a soil bacterium called Streptomyces fradiae. The 'mixture' refers to the fact that this additive contains several related compounds that work together, all produced during the same fermentation process - think of it like a family of closely related molecules rather than a single pure compound. This antibiotic mixture is used exclusively in animal feed, particularly for pigs, chickens, and sometimes cattle. It helps prevent respiratory and intestinal infections in farm animals while also promoting growth, making livestock farming more efficient and helping keep animals healthier during the raising process. Tylosin mixture is a synthetic antibiotic created through industrial fermentation. While it doesn't directly affect human dietary restrictions since it's not added to food for human consumption, consumers who prefer to avoid products from animals treated with antibiotics can look for 'antibiotic-free' or 'no antibiotics ever' labels on meat and dairy products. Agricultural authorities carefully regulate its use, requiring specific withdrawal periods before treated animals can enter the food supply.
