I purchased my pigs from the president of the association and when I went to pick them up he was showing me his pigs, he had a pair that were still breeding that were over 10 years old and maybe 15 I forgot but it blew me away how old they were. So that being said I think you did fine with your purchase. We just had our first litters a month ago with a total of 9 piglets and they are doing fine. Good luck
