The fresh chicken feces were obtained from different age 18 healthy chicken, and were not detectedchlortetracycline. The mixture standard solution of CTC and OTC was added in fresh chicken feces at the concentration of 0.5, 1.0 and 4.0ug/ml respectively. The chicken feces were divided to two groups,one were put in the incubator under photophobic condition; another were under the natural illumination.Samples were collected after 0, 0.5, 1, 2, 3, 5, 7, 9, 12 and 15 days, The concentration of chicken feceswas determined by HPLC. According to the theory of degradation kinetics, we fitted the changed trendof concentrations in chicken feces under different time and studied the degradation characteristics ofchlortetracycline in chicken feces.
