The study was carried out on two farms (A and B) involving 60 calves, aged 1—2 months, with the signs of bronchopneumonia. Calves from farm A showed severe bronchopneumonia signs (high temperature) while animals from farm В displayed signs of moderate bronchopneumonia as well as diarrhoea. In each farm the calves were divided into two equal groups. The calves of group I were treated with Bioflumeq, a soluble powder containing flumequine as an active ingredient. The calves of group II were also given antibacterial drugs for 5 days. During clinical examination lasting 7—10 days the following aspects were registered: respiratory rate, nasal discharge, cough, rectal temperature, appetite, general condition and diarrhoea. The results indicated that Bioflumeq reduced clinical signs of severe bronchopneumonia after 7 days. Better effects were observed in calves with moderate signs of bronchopneumonia and diarrhoea. The calves recovered after 5 days and diarrhoea disappeared after 3 days.
