The objectives of the studies was to evaluate a therapeutic efficacy of enrofloxacin in salmonellosis of pigs in field conditions. The experiments were performed on 425 weaners with clinical symptoms of salmonellosis treated with Baytril at a dose of 2.5 mg/kg bw for 5 days. The efficacy of Baytril was compared with that of chloramphenicol which up to now gave the best effects in a chosen farm. Chloramphenicol was used in 185 sick pigs at a dose of 5.0 mg/kg bw for 5 days. The efficacy of Baytril was evaluated on the basis of time of diarrhoea persistance, percentage of cured and died treated weaners. The antibiotic sensitivity tests of S. choleraesuis to enrofloxacin were also included. It was found that out of 425 treated weaners with Baytril only 3.8% of pigs died; in controls (animals treated with chloramphenicol) 13.5% of weaner died. Seventy five percent of S. choleraesuis isolates were highly sensitive and 25% of isolated were mildly sensitive to enrofloxacin. Besides neomycin more than 50% of the isolates were resistant or slightly sensitive to other antibiotics studied.
