A non-nutritive, ambient temperature-processed floating pellet (ATFP) was used as a medium to deliver apramycin (Eli Lilly and Co., Greenfield, Indiana), 52% active, and oxytetracycline hydrochloride (Pfizer, Inc., Lee's Summit, Missouri) (91% active) to channel catfish, Ictalurus punctatus, experimentally infected with Edwardsiella ictaluri. The drugs were fed at 50 mg of active antibiotic per kilogram of fish per day. Two medicated feeding trials were run for 10 consecutive days in troughs with channel catfish, beginning 24 hours after exposure to E. ictaluri. Mortality in the non-infected control population in Trial 1 was 7.6%, significantly (P < 0.05) lower than the 88.3% of the infected, non-medicated fish. Fish fed diets containing apramycin experienced 62.5% mortality, while fish fed diets containing oxytetracycline hydrochloride had 63.3% mortality. Mortality of the two medicated groups were significantly (P < 0.05) different from either control group. In Trial II, the 23% mortality in the non-infected group was significantly lower than the 48% mortality in the infected, non-medicated group and the 41% mortality in the oxytetricycline hydrochloride-medicated group, but not different than fish fed diets containing apramycin (28%). Mortality of the two medicated groups in Trial II were significantly different from each other. The presence of thc apramycin and oxytetracycline hydrochloride in the ATFP was demonstrated by the antibiotic diffusion method on agar plates swabbed with E. ictaluri. |
