There has been an unusual spike in the number of processed deer showing signs of Johnes' disease in the first half of 2018. We have contacted farms supplying these animals and supported a Deer Health Review focused on Johne's disease. This has helped understand the cause of the spike. Our latest data suggests it may be abating. Still, as the new processing season begins we recommend any farmers seeing a tail end of poor performance in their weaners to immediately contact us or their local veterinarian to establish and treat the cause.
