Johne's Disease — Getting a Handle on This Silent Profit Robber

Johne’s disease, a bacterial disease of ruminant animals, can be incredibly difficult to manage, as there is no treatment and production losses can occur even without clinical signs being present. What’s more, few animals actually exhibit the wasting and diarrhea associated with infection, unless under stress. It means that for every visibly sick animal you may have several more infected animals in the herd who are performing sub-par and spreading the disease to the next generation.

In this video, Dr. Karin Orsel, DVM and assistant professor with the University of Calgary, explains why Johne’s disease can spread without farmers fully realizing the extent and how it can be bought into a herd. Dr. Orsel also lays out several strategies for preventing the disease’s spread, an important consideration as it’s estimated as many as 60% of Alberta’s herds carry the bacteria.
