I never knew the name of it. It was for 400 hogs. 10 pens total. Faced the south.

It has 20 ft under the north roof with hinged doors(for Summer) on the upper half of the north wall. Had heated floor.

It had 20 ft open to the south which is sloped to the underground manure pit. Had heated floor with a big valve so you only turned it on after bigger snow storms.

The slot for the pit was about 6" at the bottom off the sloped area. You would put in a 1 1/2" diameter pipe for smaller pigs in that slot.

The manure pit roof(mostly unused), was also the sorting alley and load-out area. It was 8 ft x 8 ft x 100 ft long.

It used 5 Smiley high moisture corn hog feeders, between the pens. Filled by 6" auger under the roof attached to Harvestore with pressure switches in each feeder, to tell when they were full enough.

Waters were about 3 ft from the slot to the manure pit. Idea was the pigs would poop down there, instead of inside the building. But, as always, about 1-3 pigs would poop inside on the north wall. We tried to hand scrap manure to the manure slot, twice daily because it helped in the long run.
