Investigators believe an electrical issue sparked a blaze that killed more than 4,000 hogs late Wednesday at a farm in Moore County.

The hogs that died, the farm's owner said, weighed anywhere from 14 to 45 pounds and were valued at about $400,000. They were in a nursery building that was worth about $600,000.

Fire officials said one of the biggest challenges in fighting the fire was a lack of water in the rural location – Skill Road off N.C. Highway 705.

Insurance adjusters were expected to arrive on the property Thursday, and the farms' owner said the company plans to rebuild.
