Abstract
The current study examined the prevalence of Eimeria infections in domestic rabbits in China A total of 480 faecal samples were collected from 48 farms in 14 provinces of China Each faecal sample was subjected to oocyst counting and oocyst isolation The Eimeria species from samples containing isolated and sporulated oocysts were morphologically identified under microscope The overall prevalence of infections was 419 201/480 Northwest China had the highest prevalence 70 followed closely by Northeast China 65 and Southwest China 625 The prevalences in North China 34 and South China 258 were significantly lower The large and medium farms had lower prevalences 342 and 372 respectively than the small farms 614 Coccidian oocysts were found in 422 76/180 of faecal samples from meat rabbits 40 28/70 from angora rabbits and 447 85/190 from Rex rabbit In total ten species of Eimeria were identified from oocystpositive samples Concurrent infection with two to eight Eimeria species was found E perforans was the most prevalent species 352 followed in order by E media E magna E irresidua and E intestinalis with prevalences of 313 288 194 and 148 respectively Taken together These results reveal the characteristics of the prevelance of rabbit coccidia infection in China including the distribution the scale of farming and the species which are indispensable to the control of rabbits coccidiosis in ChinaWe thank Associate Professor Sufang Fang from Hebei North University for her technical guidance on the morphological verification of oocysts This study was supported by the earmarked fund for Modern Agroindustry Technology Research System CARS44
