"You know it's a hurt feeling, and I hurt, too," LMPD Traffic Unit investigator Donney Smith said. "I don't like it."

Louisville Metro police said 150 pigs were on board. The pigs were being transported to the Swift plant in Louisville from BNB Farms in Bryant, Indiana.

Smith said Swift plant officials arrived at the scene and after they euthanized the injured animals, they loaded the surviving pigs onto a different truck and took them to the Swift plant.

Smith said speed was not a factor in the crash, adding that the load shifted and overturned.

The driver of the tractor-trailer was taken to University of Louisville Hospital with minor injuries.

No other vehicles were involved.

Crews from the USDA and Metro Animal Services also assisted police at the scene.
