Abstract
Prevalence and Associated Risk Factors of Eimeria Infections in Dairy Calves in Haramaya University, Haramaya and Harar Towns
Highlights
Eimeria infections are one of the most common and important disease of cattle worldwide
The study was conducted in dairy farms in Haramaya University, Haramaya and Harar towns which are found in Eastern Hararghe Zone, Eastern Ethiopia
The overall prevalence of Eimeria in calves recorded in this study (24.4%) was lower than previous reported in Addis Ababa and Debre Zeit by which was 68.1 % [12]
Summary
Eimeria infections are one of the most common and important disease of cattle worldwide. Bovine coccidiosis has been observed in almost all areas where cattle are raised and is usually most common and important in calves younger than 1 year. All calves managed under conventional systems are exposed and become infected early in life. At least 13 different coccidial species are known to infect cattle, but not all are pathogenic. The two most pathogenic species are E. bovis and E. zurnii [1]. Eimeriosis in cattle is a problem of confined animals kept under intensive husbandry practices. The disease is more common in housed animals than in those on pastures. In associations with other enter pathogens, coccidia have been indicated as an important cause of diarrhea in calves [3]
