Background and Objective: Tetracyclines are currently among the most widely used antibiotics for growth promotion in the broiler breeding sector. The current study seeks to evaluate the presence of antimicrobial activity in tissue of broiler chickens that have been fed a classic diet supplemented with the antibiotic oxytetracycline. Materials and Methods: A four-plate test was used to compare antimicrobial activity in tissues of chickens that had and had not been fed an antibiotic. Results: The results of this test showed that antimicrobial activity first appeared in the kidneys, followed by the liver and then adipose tissues. The most intense antimicrobial activity was observed in adipose tissue, whereas no activity was detected in muscle tissues. Conclusion: The inclusion of oxytetracycline in broiler chickens’ diet as an antibiotic growth promoter induced the appearance of antimicrobial activity in the kidneys and adipose tissue with an increasing intensity according to the time of the breeding period.
