A Comparative Study on Prevalence of Coccidian Parasites in Broiler Chicken (Gallus gallus domesticus), Japanese Quail (Coturnix coturnix japonica) and Wild Pigeon (Columba livia)

Present study was conducted to detect the prevalence of coccidiosis in Broiler chicken (Gallus gallus domesticus), Japanese quail (Coturnix coturnix japonica)and wild pigeon (Columba livia). Three hundred fecal samples of each species were collected and examined from January 2010 to June 2010. Prevalence was detected by using three diagnostic techniques i.e., by direct smear method, sedimentation technique and floatation technique. The mean prevalence of coccidiosis detected during the study period was 17%, 21% and 23% in broiler chicken, Japanese quail and wild pigeon respectively. The prevalence of infection increased with the rise in temperature from January to June indicating a positive relationship, whereas, prevalence of coccidiosis in all three species of birds did not show any direct relationship with the relative humidity.
