They also are typically good mothers.
We farrow our sows outside in the warm months and many times the sow just goes into the brush and builds a nest.
In the winter we use huts or bring them into the barn and put them into a 12 x 12 stall. Contrary to what you may have heard or read, not all Tamworth swine are great mothers. Most of them are, but we breed for sows that will farrow outside with out assistance.
I've had a few since we started breeding Tamworth's that weren't very good mothers. I like a sow that takes her time laying down and "talks" to her pigs as she does to let them know "get out of the way."
If they hear a pig squeal they move or jump up whichever the situation calls for.
I need low maintenance hogs. The Tamworth sows we have are very capable of having their babies and caring for them just like nature intended!
