Johne’s less prevalent in Western Canada than in the East

A recent paper was published in the journal Frontiers in Veterinary Science by a research team at the University of Saskatchewan’s Western College of Veterinary Medicine led by Dr. Cheryl Waldner and her graduate student, Paisley Johnson. The study was part of the Canadian Cow-Calf Surveillance Network project funded by the Beef Cattle Research Council and Saskatchewan Agriculture.

The prevalence of cows that tested positive for MAP antibodies in the blood (serology test) was still low at 1.3 percent and only 0.9 percent tested positive on the fecal PCR test (pooled testing confirmed by individual testing).
