Johne's could be present in 50 of flocks, study claims

摘要

More than half of UK flocks could have elevated culling rates because of Johne's disease, says a leading sheep researcher reacting to flock survey results. A growing body of University of Liverpool data show ovine Johne's disease (OJD) is present on 59-65 of farms surveyed in academic and industry trials, according to Peers Davies, reader in livestock health and welfare at the university, speaking at the National Sheep Association event.
