Samples were collected at time 1, 3, 7 and 10 days after drug administrations. Tylosin was detected using microbiological method. Tylosin concentrations in different tissue were detected. High concentration of 61.78±5.83, 315.97±73.07 and 3956±645.59 µg g-1 were detected in liver, kidney and muscle, respectively at day 1. The highest concentrations of 19185±2966.9 µg g-1 were noted at the site of injection at day 1 and persisted for 10 days. Low concentrations of 1.00, 1.5±0.24 and 5.22±0.20 µg g-1 were noted in the liver, kidney and muscle at day 10, respectively. It is suggested that high tissue levels may create a reservoir of drug from which drug was released slowly into the circulation.} }
