Mycotic abortion is an important reproductive problem of cattle all over the world. It is caused by a number of different species of fungi and yeasts. The epizootiology of the disease is not clearly understood but it is assumed that mouldy hay, straw and feeding stuffs are the most probable transmitting agents. Mycotic abortions in cattle have been recorded usually after first 6 months of gestation. Aborted animals usually suffer from retention of placenta. No treatment has yet been evolved for such abortions.
