Description

Coccidiosis is a common parasitic protozoan disease of cattle, particularly weaned calves, in Alberta. Bovine coccidiosis is seen most frequently in calves that are three weeks to six months of age. Calves become infected when placed on pastures or lots contaminated by older cattle or other infected calves. Mature cattle may become infected when they are brought in from pastures and crowded into feedlots or barns. At least nine species of coccidia occur in Alberta cattle, but only two, Eimeria zuernii and Eimeria bovis, cause severe clinical disease. To a lesser extent, Eimeria alabamensis also can cause clinical disease. The prevalence of the different species of coccidia can vary considerably between farms, regions, seasons and age groups.
