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.

选取不同日龄健康鸡18只，实验期新鲜鸡粪，，经检测不含四环素类药物，然后加入金霉素标准液，使得各样品中制得的相应药品的浓度为0.5ug／mL、1.0ug／mL、4.0ug／mL，分为两个实验组，第1组放入培养箱中避光黑暗条件下；第2组置于室外自然光下，定时取样，取样时间为0、0.5、1、2、3、5、7、9、12和15d，鸡粪中药物的浓度用本实验建立的高效液相色谱法测定，根据药物降解动力学原理，对鸡粪中药物的浓度随时间的变化趋势进行曲线拟合，研究金霉素在环境鸡粪中的降解动态规律。
