Importance of Johne’s Control

The direct economic impact on farms will vary between farms and depends upon the proportion of cattle infected and the extent to which infection has progressed in infected cattle.  Infection can contribute to reduced milk yield and increased susceptibility to other conditions such as infertility even before the more obvious signs of disease appear. Infected cattle may be culled due to poor productivity before a diagnosis of Johne’s disease. Therefore Johne’s disease can be an unrecognised cause of excessively high cull rates.
