The moisture content of fresh manure was tested by using GB 5576-88, the TN content,. the TP content and the organic matter content in dried fecal samples were tested by using NY 525-2002, the copper content and the zinc content were detected by using GB/T17138-1997 in order to monitor seasonal changes of pollution factors about breeding cattle manure in dairy cow breeding of district. The results showed that the lowest moisture content in fresh manure was in spring, the highest was in winter. The seasonal changing rule of ifve testing indicators and every annual average in dried fecal samples was organic matter>TN>TP>Zn>Cu except reverse order of total nitrogen and total phosphorus in summer. The lowest total nitrogen content of breeding cattle was in summer and the highest was in winter, the lowest total phosphorus was in autumn and the highest was in summer, the lowest organic matter content was in summer and the highest was in autumn, the lowest copper content was in summer and the highest was in spring, the lowest zinc content was in spring and the highest zinc content was in summer.
