“The pigs are born normal, but what happens is when the virus actually makes it to them, when they nurse on the sow, they can’t absorb nutrients from that. So, they end up dehydrating and dying,” Preisler said.

Preisler said while they had a bad experience with the virus, pork producers are more prepared going into the next month or so.

To ward off the disease, farmers have boosted the animals’ diets, resulting in hogs that weigh about 215 pounds.
