    Study on Prevalence of Poultry Coccidiosis in and around Ambo, West Shewa Zone, Oromia Regional State, Ethiopia
    (2014-06) Solomon Shiferaw; Waktole Terfa
    A cross sectional study was conducted on poultry coccidiosis of local and Rhode Island breed from October 2013 to February 2014 in and around Ambo town, Ethiopia. The objectives of this study were to determine the prevalence of coccidiosis, to identify species of Eimeria and to assess potential risk factors(breed,age sex and manegment system). The study involved postmortem examination of chickens, mucosal scraping and parasitological examination of oocyst, gross and histopathological examination and identification of Eimeria species. Out of 390 examined chickens 18.7%(73/390) of them were harbor different Eimeria species. Statistically no significant differences p˃0.05 (χ2=0.921, p= 0.337) was noted between young and adult age groups. Additionally there were no significant differences between local and Rhode Island Red breed(χ2= 0.16, P>0.05), management systems (extensive and semi intensive)(χ2= 2.245, P=> 0.05 and sexes(χ2= 3.609, p˃0.05). In the attempt made to identify the prevalent species of coccidian in the study area, five Eimeria species were identified, namely Eimeria. tenella, Eimeria. necatrix, Eimeria. burnette, Eimeria. maxima and Eimeria. acervulina with the prevalence of 60.27%, 15.06%, 9.6%, 1.4% and 1.4% respectively. Eimeria. tenella was the predominant species in the study area. In conclusion, the present study showed that coccidiosis is an important disease of poultry in the study area and further strategy needs to be implemented to reduce the loss due to coccidiosis.
