a: Enrofloxacin (ENR) concentrations in feces, collected during 3 days of treatment (sampling at 0, 10, 24, 34, 48 h and 58 h). With oral bolus administration in group 1 (n = 6): conventional: 2.5 mg/kg BW (1x daily); group 2 (n = 6): half dose: 1.25 mg/kg BW (1x daily); and IM administrations in group 3 (n = 6): conventional: 2.5 mg/kg BW (1x daily); group 4 (n = 6): double dose: 5 mg/kg BW (1x daily). b: ENR concentrations in the different gastro-intestinal segments: duodenum, jejunum, ileum, cecum, colon and feces. Sampling was performed 10 h after the final ENR administration (time point 58 h) in each treatment group. ↓ marking means no SD was presented because of the lack of sufficient data (either insufficient intestinal sample collection or values not quantifiable)
