The risk of transmitting the livestock virus PPRV, which threatens 80 percent of the world’s sheep and goats, increases with certain husbandry practices but not herd size. A new study, led by researchers at Penn State, investigated how transmission of PPRV might change at different scales and identified specific husbandry practices associated with increased odds of infection—including the introduction of sheep and goats to the herd, sheep or goat attendance at seasonal grazing camps, and the sales or gifting of goats from the herd.
