The coccidia are the cause of coccidiosis, a disease of considerable importance in domestic animals. The discovery of several species causing extensive pathological damage and mortality in poultry, cattle, sheep, goat, pigs and several other animals have increased their importance. Coccidiosis causes a great economic loss in the poultry industry due to high rate of morbidity and mortality, sub optimal growth and conversion efficiency and loss of egg production. The present study showed that the broiler chicken in Gangapur and Vaijapur Tehsil of Aurangabad District in Maharashtra shows great occurrence of Eimeria in poultry. The Gangapur and Vaijapur talukas are come under low rain fall zone and poverty. So business point of view people are turn towards poultry, so to encouraging them we try to show overall scenario of coccidiosis in this region.The species occurring in broiler chicken in this region are as follows: - Eimeria tenella, Eimeria necatrix, Eimeria brunetti, Eimeria acervulina, Eimeria maxima, Eimeria praecox, Eimeria mitis, Eimeria nikamae, Eimeria tarabaie and Eimeria shivpuri.
During the period of 8 months (Monsoon and Winter Season) i.e. from, June, 2013 – January 2014, total 704 faecal samples from Gangapur and 699samples from Vaijapur were examined for coccidial infections, out of which 254 samples from Gangapur and 251 samples from Vaijapur were positive respectively. The percentage of prevalence being 36.07% and 35.90% respectively. Comparative study shows minor differences in prevalence.
