That's according to a study from Oregon State University and publicized Thursday. Reinaldo Cooke, an associate professor and animal scientist based in Burns, conducted the research, which appeared in the Journal of Animal Science in late March.
When wolves attack a herd of cattle, Cooke said in an interview Thursday, the surviving animals' life experience is "completely altered" by the event. Animals become jumpier around humans and pets, the cows give birth to smaller calves, and the animals are more likely to get sick.
