[Therapy trials with enrofloxacin (Baytril) in a laying hen flock with Salmonella pullorum infections]

The course of a disease due to Salmonella pullorum in laying chickens is described. The experimental application of enrofloxacin (Baytril) at a dosage of 100 mg/l drinking water for 10 days resulted in a stop of the mortality rate, increment of egg production and reduction of Salmonella excretion. A recurrence of the disease was observed in the fifth week following the end of treatment with high mortality and decreasing egg laying. The treatment lead to a short-dated success but a permanent elimination of the germ from the flock was not achieved.
