A spokesman for Northern Ireland Fire and Rescue Service told the BBC: “We had six appliances at the scene.
“When we arrived we found two of the houses with pigs inside alight. We managed to save five of the houses.
“This is a very serious incident but crews reacted quickly. There is no idea of the cause at this stage.
“It’s unfortunate and you really feel for the farmer this morning. It’s likely we will be there for another few hours.”
