Congrats on the sow. Here in SW OK it is pretty common to find old sows that have never had a litter. Killed two big old black sows on the 7th of this month.Both were about one month along with their first litter.

This sow was at least three years old and was probably older. She weighed 188 pounds field dressed. The other one weighed just over 175 pounds field dressed.
