We just slearned from our Vet today that UW Vet Diagnostic Lab have completed Johne’s Disease testing on our flock with the most advanced and accurate Direct PCR tests and our entire flock from age 1 on up is negative for Johne’s Disease. They were negative for both Johne’s and OPP a year ago as well. See spring issue of Sheep! magazine for a reader-contributed article I wrote in cooperation with our local vet and one of our state experts on Johne’s Disease Testing recent advances in testing for Johne’s Disease.
