A recap of Johne's disease

Johne's disease is a common problem in Southland.

It’s caused by a bacteria that damages the gut lining, leading to two main signs:  

  1. Watery “hose-pipe” diarrhoea.  

  2. Progressive weight loss.  

Infection usually occurs in young calves. The bacteria then lies dormant in the cow for a number of years, with these clinical signs often not apparent until they are at least 3-4 years old. These later-staged diseased cows shed the most bacteria leading to a higher risk of transmission. 

Regular testing for Johne’s through bulk milk testing provides a greater chance of identifying affected cows (who may not have visible symptoms) and removing them from the herd.  

Unfortunately, given the nature of the disease, it can take several years of herd testing and culling before a large improvement in case numbers can be seen.   

Johne’s disease is costly and large numbers of affected cows can lead to huge production losses. Making a plan with your KeyVet about testing for and managing Johne’s can lead to better productivity and animal health in the long-term.
