 Commercial poultry sector is one of the most important segments of global trade and production. Coccidiosis, a worldwide disease of economic importance, significantly influences the production potential of this sector. To decrease the prevalence and consequent economic losses, identification of factors, which influence the frequency and persistence of illness, is pre requisite. A retrospective case control study was conducted for a period of one year in order to identify the risk factors associated with coccidiosis infection. Total of 70 broiler and 15 layer flocks of varying age and population sizes were selected as cases. For each case flock, one apparently healthy flock of similar breed, age and population size was also selected as control. Data of these 85 case control pair flocks regarding disease incidence and associated factors, recorded from January through December 2018, were analyzed for measures of association. Monsoon season, no vaccination, broiler breed, winter season, post monsoon season, spring season, open shed, wet litter, ≤ 4 weeks age, coccidiostat excluded feed and crowding appeared as putative risk factors exhibiting significant (P < 0.05) association with coccidiosis infection by odds ratios of 2.88, 3.35, 3.66, 5.70, 6.77, 7.12, 8.14, 8.50, 9.28, 9.33 and 11.40 respectively. Non-significant (P > 0.05) association of coccidiosis infection was recorded with layer breed and scarce flushing with odds ratios of 0.73 and 0.94 respectively. Incidence and persistence of coccidiosis infection in commercial poultry population is significantly influenced by management and seasonal factors.
