Abstract

Abstract: Ofloxacin is one of the most widely used antibiotics in the livestock and poultry industry， its residue in the excrement will has the adverse effect to the environment. Ofloxacin’s degeneration in the chicken excrement had been studied in different conditions. The results showed that ofloxacin in chicken excrement was very stable in photophobic condition， the degradation rate of ofloxacin was slow in the chicken excrement of fermentation，but under daylight illumination， the degradation rate of ofloxacin was high in chicken excrement.The degradation process of ofloxacin in chicken excrement could be evaluated on the basis of the first order kinetic equation as Ct=C0e-kt. Calculated by this equation， the half-life of ofloxacin in chicken excrement was (5.77±0.466) d under daylight illumination. The half-life of ofloxacin was (35.66±1.99) d in chicken excrement of fermentation.

Key words: chicken; ofloxacin; excrement; degeneration
