Abstract: The investigation of parasite infection was taken in 22 kind of herbivores，and 88 feces samples were collected in Zhengzhou zoo. The centrifugation and saturation sugar solution floatation were used in survey.The result showed that the gross infection rate was 19.13%，and the rate of coccidian infection，nematode infection and whipworm infection were 7.95%，12.50%，2.27%, respectively. The analysis of data showed that the rates of parasites infection were decreased gradually，and degrade rate was 39.95% compared with 2003，and the extent of infection reduced obviously. It also showed that the protection measure in the zoo had a good effect，all above offered reference and basis for the zoo to make correlative measure on the prevention of parasites disease in the future.
