The Survey Of Captivity Cranes In The Northeast Region

From April2012in Zhalong; Shenyang Forest Wild Animal Zoo in May; Harbin Northern Forest Zoo xianghai Nature Reserve and Changchun animal and plant Garden in September, in accordance with the requirements of the analysis of parasite.In fecal samples were found six kinds of eggs:hookworm eggs, sharp filaria (Oxyuridea) eggs poultry roundworm (Ascaridiiae), eggs, capillariasis (capillariasis) eggs and Echinostoma eggs (Echinostomatidae), was not found protozoa the spine head insects infections and parasites. Overall infection rate:Shenyang Forest Zoo is23%, Northern Forest Zoo is16%, Zhalong Nature Reserve is12%, Xianghai nature reserve is12.5%, Changchun animals and plant Garden is3.8%.Infected with the parasite species in each region is different, Shenyang Forest zoo and a breeding area of the Northern Forest Zoo cranes animal parasitic infections the poultry roundworms and capillariasis of mixed infection, intensity of infection are poultry roundwormlow capillariasis; also found different types of parasites are mixed infection, including Northern Forest Tree Zoo and Xinghai nature reserve. The study also found dissipate into the atmosphere regional self-infection was significantly higher than the individual region in captivity; Parasite infection of forest area was significantly greater than the infection rate of wetland environments; adult cranes and subadult are higher than childhood cranes.Through the caged areas Crane infection rate is lower than dissipate into the atmosphere region Crane infection; infiltration the waterborne material ground cages crane infection rate is lower than the soil ground cages cranes; rearing environment and feed human-induced factors, the infection rate of adult birds higher than the sub-adults and chicks.Software for statistical analysis, simple and intuitive that a descriptive statistical results and curve fitting model analysis.
