Coccidiosis remains a serious concern of great economic impact on domestic animals including rabbits. This study was conducted to determine the prevalence, species diversity, and associated risk factors of rabbit coccidiosis in Ilorin, Kwara State Nigeria. Fecal samples were examined using the floatation technique (positive samples were sporulated for identification of the different Eimeria species). 169 out of 215 (78.6%,) rabbits were found to be infected with Eimeria species. A total of seven Eimeria species (Eimeria coecicola, Eimeria irresidua, Eimeria perforans, Eimeria magna, Eimeria intestinalis, Eimeria stiedai and Eimeria flavescens) were identified. Of these, Eimeria coecicola was the most prevalent (48/215; 22.3%), while E. flavescens (8/215; 3.7%) was the least prevalent. Weaners (80.0%) were more infected than bunnies (79.1%) and adult (77.5%). Females had a higher infection rate (79.4%) than males (77.4%). Californian breed were more infected (84.9%) compared to Chinchila (83.7%), Dutch breed (80.9%), and New Zealand White (63.6%). Rabbits kept in the deep litter housing system had higher prevalence rate (95.2%) compared to those raised in the battery cage system (71.9%). Coccidiosis was more prevalent during the wet season than the dry season. This study concludes that Eimeria infections of rabbit is endemic in Ilorin, Kwara State with breeds and housing type been significant risk factors associated with the infection. This study provides the baseline information as the first report on the different Eimeria species affecting rabbits in Nigeria.
