What made the cows sick in Yellowstone? Life’s never been easy for John Dutton within the Yellowstone timeline. So far, he’s lost his wife, survived cancer, and there was that time someone tried to assassinate him. Still, through hard work and grit, John’s managed to keep his ranch going and even become governor of Montana.

What made the cows sick in Yellowstone?
It’s suspected that the Dutton family’s cows are sick with Brucellosis that they caught from a wild bison. Brucellosis is a real disease caused by a bacterial infection. In humans, Brucellosis causes flu-like symptoms, but in cattle, the effects are much more severe.
The disease can reduce the fertility of cattle and cause pregnant cows to miscarry. There’s no cure or vaccine for Brucellosis, which is why John’s been forced to take his herd south to (literally) greener pastures free from the disease.
