Madura cattle, which are native to Indonesia and mainly kept on Madura Island, East Java, are expected to contribute to improving the regional meat self-sufficiency. Eimeria spp. are the most pathogenic protozoans among gastrointestinal parasites in livestock but no molecular surveys of Eimeria spp. in Madura cattle have been conducted to date. In this study, a total of 183 fecal samples were collected from Madura cattle and 60 (32.8%) were positive for parasites of protozoans and nematodes by the sugar floatation method. Among the samples with parasites, Eimeria spp. oocysts were detected in 50 samples (27.3%) with an average OPG value of 1686.1. Eimeria spp. were successfully identified to the species level in 26 samples with Eimeria bovis being the most prevalent, followed by E. zuernii and E. aubrunensis. A total of 21 samples showed mixed infection of more than two species of Eimeria. E. bovis and E. zuernii have been recognized as having high virulency and, thus, these parasites are potential sources of severe coccidiosis and the cause of infections in other cattle. Although additional studies are warranted, these results can be helpful for improving the management and productivity of Madura cattle.
