This research paper describes a cross-sectional study of cattle in Lahore District to determine the prevalence of Eimeria species and risk factors associated with subclinical coccidiosis. A total of 2700 rectal faecal samples were collected from a government dairy farm in Lahore, a military dairy farm in Lahore and a peri-urban farm (Gawala Colony) in Lahore under different management practices and tested for the presence of various Eimeria oocysts. 1473 faecal samples were found positive for oocysts of Eimeria species namely E. bovis (27.05%), E. zuernii (20.14%), E. subspherica (11.72%), E. cylinderica (23.97%), E. ellipsoidalis (19.54%) and the highest (78.66%) monthly prevalence was observed in August while the lowest (35.44%) was in April. The study results showed that overall the highest (66.22%) prevalence of coccidiosis was observed in autumn followed by summer (59.66%), winter (51.77%) and the lowest in spring (38.2%). The highest (45.33%) prevalence of coccidiosis was observed in animals aged 6 to 12 months, followed by 41.35% in animals under 6 months, while the lowest (36.00%) was over 1 year. Female animals were affected more often (41.25%) than males (39.50%). In the present study, the maximum number of OPG observed was 55,000, while the minimum was 2,000.
