Abstract: To grasp the current infection status of rabbit coccidiosis in Henan Province, 465 fecal samples were collected from 11 rabbit farms and examined with McMaster counting and saturated saline flotation methods to determine the prevalence and Eimeria species in rabbits. The results showed that the mean infection rate in rabbits was 74.6%, and mostly concurrent infection with four to six Eimeria species. The mean infection rate (83.0%) and OPG value (oocysts per gram feces, 6.8×104) in the rabbits younger than 3 months (1 to 3 months) were higher than other elder rabbits. 11 Eimeria species were detected in infected rabbits of Henan, and E. magna , E. irrestidua, E. perforans, and E. intestinalis were dominant species. These findings would provided a important reference for further effective control of rabbit coccidiosis and selecting some Eimeria species for development of precocious line vaccine.
