This study was performed to identify the prevalence of cryptosporidiosis and giardiasis in diarrhea feces of Korean native calves raised in Gimje, Jeollabuk-do, with a rapid diagnostic kit. The prevalence of both diseases were classified according to the age of calf, season of sampling period, and sampled farm where diarrheic calf is commonly observed. In diarrhea feces of 431 calves, cryptosporidiosis had a high incidence rate between 1 and 3 weeks of age, whereas giardiasis showed a high incidence between 4 and 6 weeks of age. It is thought that the incidence of protozoan diseases is markedly influenced by the calf’s postnatal age. Regarding with the sampling season, the prevalence of cryptosporidiosis and giardiasis in calves was significantly higher in spring and summer than in autumn and winter (P<0.05). Among the sampled farms where both diseases are commonly observed, cryptosporidiosis was more frequently detected than giardiasis in calves. Particularly, in farms where cryptosporidiosis is common, it tends to be a disease that is difficult to eradicate as it occurs continuously throughout the year. Hygiene management such as regular cleaning and disinfection of the livestock and the surrounding environments is considered necessary to reduce and prevent damage from these protozoal diseases.
