Coccidiosis is a protozoal, highly infectious, fatal and the most prevalent poultry disease, which is caused by species of Eimeria. It results in massive destruction of intestinal epithelium leading to bloody diarrhea, poor weight gain, low FCR and high mortality. The present research is designed to identify the prevalence of coccidiosis in broiler chickens in district Dera Ismail Khan, Pakistan. The study was conducted from November 2015 to April 2016 and 300 gut samples were examined and overall prevalence found was 44%. One hundred fecal samples from different broiler farms were also investigated during the same period. The prevalence of coccidiosis infection among adult broiler chickens was 41.51% and among young broiler chickens was 65.96%. Four species of Eimeria; E. tenella (24.24%), E. maxima (31.06%), E. mitis (31.82%) and E. necatrix (12.88%) were observed. The prevalence of Eimeria infections was highest in the month of April (71.83%) while lowest during December (25.71%). The prevalence of coccidiosis was higher at the farms where the management practices (sanitation and medication) were not satisfactory particularly litter moisture. A strong correlation was found between the prevalence of coccidiosis and age of the chickens. The differences were attributed to the managerial and environmental conditions especially due to climate change.
