Therapeutic efficacy of doxycycline hyclate in experimental Escherichia coli infection in broilers.

Abstract

Treatment of experimentally induced colibacillosis in broilers with doxycycline hyclate through the drinking water was just effective at a dose of 200 mg/kg body weight (1000 ppm). The achieved therapeutic effects were similar to those of tetracycline at the same dose and of flumequine at a dose of 19 mg/kg body weight (100 ppm).
